Sinister: A Suzuki Katana Restomod by dB Customs

Suzuki Katana restomod by dB Customs
The word ‘iconic’ gets thrown around too easily sometimes, but there’s no disputing the Suzuki Katana’s claim to it. Its radical looks might not have won everyone over when it first hit the scene in 1981, but it went on to build a true cult following. So if you’re going to build a Katana restomod, you’d better do it justice.

Darren Begg sure knows how to treat the Katana right. He runs dB Customs out of Ottawa, Canada, and has a knack for building jaw-dropping 80s restomods and race bikes. Not one to sacrifice function for form, he also has a tendency to drown his bikes in well-judged performance updates.

Built for a client, this sinister Suzuki Katana is positively dripping with style. Darren’s brought it up to date with major changes to the bodywork, engine and chassis—but it hasn’t lost any of its retro charm.

The project started out with a 1982-model Suzuki GSX1100S Katana, but very little of the original bike remains. For starters, the engine’s had a full overhaul. It’s now running 1,216 cc Wiseco pistons, with Ray Mancini at Xtreme Motorsports responsible for reworking the head.

Other upgrades include oversized stainless steel valves, Webcams camshafts, and Hayabusa rods with custom spacer plates. There’s also a new ECU from NWT Electronics, and a Dynatek Dyna 2000 ignition with new coils, all made to work with Accel wires. Take a peek behind the front wheel, and you’ll also spot a new Setrab oil cooler.

The Katana inhales through a row of Yoshimura TMR-MJN carbs, and out through a Racefit titanium exhaust system. (You can get an earful of it here [https://www.youtube.com/watch?v=Oj_nEq0H8pI].)

Darren gave equal attention to the frame. It’s been braced in all the right places, and mated to a reinforced Suzuki Bandit 1200 swingarm. It’s also running a full complement of Öhlins suspension parts; upside-down forks for the front, and burly piggyback shocks for the rear.

For the wheels, Darren settled on a pair of lightweight aluminum hoops from Dymag, with Avon Spirit ST tires. Twin Brembo brake calipers sit up front, with a single Brembo unit sitting on a custom-made bracket at the back. Both sides run with new braided stainless steel hoses.

All of the Katana’s bodywork looks more or less original, but much of it has been swapped out. Darren kept the original fuel tank—but modified it to accommodate a new filler cap from Newton Equipment.

The front fairing and side covers are new-old-stock parts, fitted with a titanium coated windshield from Ohno-Speed in Japan. A pair of carbon fiber fins sit just below the headlight nacelle—those are from Magical Racing, also in Japan. A carbon fiber fender finishes off the front.

Darren sourced the bike’s new tail cowl, plus its headlight and taillight, from Unicorn Japan. The seat is a bolt-on part from Daytona and AC Sanctuary—two of the best names in the classic Japanese sportbike scene. A tail tidy from Ohno-Speed keeps the back end of the bike clean, while offering a discreet place to mount the license plate.

Darren went all-out on the rider cockpit too, starting with a set of custom-machined yokes. The clip-ons are ABM touring bike items, sitting a little higher than the usual race bike fare for added comfort. They’re fitted with a Yoshi throttle, Driven Racing grips, Brembo levers, and switches from NWT Electronics.

A Koso RX-2 gauge cluster sits front and center, while Rizoma bar-end mirrors flank the bike. Darren finished the bike off with slim Koso LED turn signals and Sato Racing rear-sets.

A menacing black paint scheme drives the point home, punctuated only by a handful of red and white accents. Those period correct Suzuki and Katana logos aren’t stickers either—Darren’s go-to paint shop, Sketch’s Ink, laid the entire livery down by hand.

Kitted to the nines with a flawless stance, this icon looks even better than the day it rolled off the factory floor. Long live the Katana!

Two smoking hot BMW K1100RS café racers from Powerbrick

BMW K1100RS café racers by Powerbrick
Powerbrick has the most apt name in the custom motorcycle business. The Dutch workshop specializes in making parts for K-series BMWs, affectionately known as ‘flying bricks.’ And every part or custom bike they make has an edgy performance vibe to it.

For their latest project, Powerbrick has upped the ante in K-series customization, with a pair of striking BMW K1100RS café racers. Featuring a staggering number of one-off parts, the bikes are nearly identical—save for their inverted color schemes, obviously.

BMW K1100RS café racer by Powerbrick
Powerbrick started with two 1994-model BMW K1100RS donors, then proceeded to rebuild them from the inside out. Dubbed ‘Vengeance’ [above] and ‘Lenience’ [below], both BMWs have had their engines overhauled. Notable mods include ported heads, enhanced timing with an NGK ignition system, and a hydraulic clutch conversion.

It’s not just about outright power. According to shop boss Tim Somers, the idea is to create a punchier connection between your right hand and the rear wheel.

BMW K1100RS café racer by Powerbrick
Also present are new RC Racing aluminum radiators, with SamcoSport silicon hoses for extra performance and style. Perched on each flying brick’s inline-four motor is a row of DNA filters; less visible are the new Bosch EV14 injectors. On the exhaust side, each K wears a pie-cut stainless steel four-into-one system from MAD Exhausts, fitting with a Powerbrick muffler.

Going deeper, Powerbrick rewired each K with a Bluetooth-enable Motogadget brain. A NOCO Lithium battery powers each system, with a Ctek charging point wired in.

BMW K1100RS café racers by Powerbrick
These K1100s also sport a slew of chassis mods. Powerbrick fitted them with new yokes from their own catalog, each with an integrated housing for a tiny Motogadget speedo. A set of BMW S1000RR forks does duty on both bikes; one with Bitubo cartridges inside, and the other with BMW M1000RR internals.

An adjustable shock from TFX Suspension sits at the back of each K. Their wheels are billet aluminum items from AC Schnitzer. They’re actually designed for the BMW R nineT, but Powerbrick made them work with custom-made adaptors. The braking systems use Brembo components throughout, with new brake lines from Venhill.

Rather than fight against the deeply scalloped, and slightly gawky, lines of the K1100RS’ fuel tank, Powerbrick opted to customize the rest of the bike’s bodywork to complement it. Most notable are the new subframes, each machined from a mammoth aluminum billet. It’s a seven-part design that accommodates not only the custom seat, but also the electronics, a small rear cowl and an integrated taillight.

The design is super sano, right down to the seat mounting mechanism. The tail end of the seat slides into place under the rear cowl, with two bolts hidden under the tank securing the front.

BMW K1100RS café racer by Powerbrick
It’s one of many well-judged details on these builds that help them look as slick as they do. “I aimed for better-than-factory quality,” says Tim. “By machining the entire rear of the bikes from computer models, I managed to make it look like they are production bikes.”

“I opted for a lot more laser and computer-guided production parts than I did before, eliminating any human errors or inconsistencies. The right side of the bikes has completely been opened up, with just the battery being suspended above the engine. I managed to do this because we threw away the entire loom and redid all the wiring in a more efficient way.”

BMW K1100RS café racer by Powerbrick
All of that consideration goes right down to the smaller details too. The cockpits are fitted with Powerbrick clip-ons, Brembo controls, and Motogadget push buttons and bar-end turn signals. Powebrick rear-set foot controls sit lower down.

Other bolt-on parts from Powerbrick’s catalog include the headlight cowls, each wrapped around a Koso LED headlight, plus the gas caps and tank roundels.

Top marks to Powerbrick for the matching Marlboro liveries too. Executed in a traditional red and white, and in contrasting black tones, each is offset with a number of color-matched details. Royal Kustom Works was responsible for the paint work, while Europe’s favorite motorcycle upholsterer, Silvermachine, did the seats.

Building two bikes at once is no small task, and Tim is quick to give credit to Powerbrick’s newest team members. “These are the first bikes that I’ve built since the team was expanded with some amazing guys: Sasza Tuahatu and Sam Clercx. They are industrial designer students and have been of amazing help!”

Once again, Powerbrick has established that they know how to squeeze the most out of the often-underappreciated K. And if these tickle your fancy, get in touch with the crew and take your pick—they’re both for sale.

Speed Read: Sideburn x Cheetah’s custom Indian FTR and more

Custom Indian FTR by Sideburn and Cheetah and other custom motorcycles
Unveiled this week: a custom Indian FTR, designed by Sideburn and Cheetah. Plus a Triumph Bonneville from Indonesia, a Triumph Bobber from France, and an impossibly slick Ducati Monster 600 café racer from Italy.

Custom Indian FTR by Sideburn and Cheetah
Indian FTR by Sideburn and Cheetah One of the biggest custom bike shows on the calendar, the Bike Shed Show, wraps up today in London. It’s a flurry of visual treats, with builders often rushing to finish their projects in time to wheel them into the show. This shiny Indian FTR broke cover at the Bike Shed this weekend—which is impressive, when you hear how far apart the collaborators that worked on it are.

The brains behind this build are Gary Inman, the UK-based founder of Sideburn magazine, and Toshiyuki ‘Cheetah’ Osawa, one of Japan’s leading custom motorcycle builders. The concept was to build a bike that would play on the FTR’s flat track heritage, while sprinkling in nods to the blossoming grassroots flat track scenes in Japan and the UK. Appropriately dubbed ‘Tokyo Connection,’ it radically reimagines the 1,203 cc roadster’s silhouette, with a one-piece tank and tail unit.

Custom Indian FTR by Sideburn and Cheetah
“Cheetah is a complete pro,” Gary tells us. “He explained his workload was huge and the only way he could hit our deadline was to finish the bike very close to the planned Bike Shed Moto show debut by flying over with the bodywork.”

Yes, you read that right. Since Cheetah couldn’t get to everything in time, he put all of his focus into fabricating a monocoque body for the FTR. The bike would also need a new subframe and a custom aluminum fuel cell to go under the seat, so those were outsourced to Toshihiro Watanabe at Garage Ducktail.

Custom Indian FTR by Sideburn and Cheetah
“In terms of design, I deliberately ignored the definition of custom bikes or racing bikes, which call for small petrol tanks,” says Cheetah. “Instead, for the FTR, I created a larger petrol tank cover and crafted a line that narrows from the cover to the tail cowl. A simple, yet beautiful body line that can be appreciated not only from a side silhouette but also from directly behind or at a diagonal angle”

While Cheetah sculpted the FTR’s new body, Toshihiro sent the fuel reservoir and subframe to Gary to fit it in the meantime. Gary also flipped through the Sideburn Rolodex, gathering together bolt-on parts from companies that he’s collaborated with before. On went an S&S Cycle exhaust, along with rear-sets, levers, a radiator cap and an oil tank cap from the Indian Motorcycle x Gilles Tooling collection.

Custom Indian FTR by Sideburn and Cheetah
The front wheel was swapped out for a 19” unit from an Indian FTR Rally, and the original rear hub was re-laced to another 19” rim, courtesy of Hagon wheels. The parts spec also includes Dunlop DT4 tires, Neken flat track handlebars and Rizoma turn signals.

With bike nearing completion, Cheetah put the finishing touches on the monocoque body by adding a spun texture to the aluminum. Atelier Tee upholstered the seat, S Paint works handled the paint, and Tomomi ‘Shakin’ Shimizu laid down the lettering.

Custom Triumph Bonneville by Thrive
Triumph Bonneville by Thrive Motorcycle It’s been a minute since we’ve heard from Thrive Motorcycle, but the Jakarta-based shop hasn’t been dormant. They’ve just unveiled their latest build—a 2015-model Triumph Bonneville Newchurch with a number of interesting details.

The commission came from a family member of a friend, who wanted to spruce up his Bonneville. Thrive kept some of the Bonneville’s original character, but mixed in a number of touches that cover myriad styles; from street trackers to classic UJMs.

Custom Triumph Bonneville by Thrive
Thrive kept the Bonneville’s fuel tank, but dressed the bike with new front and rear pieces. The headlight nacelle and high-mounted front fender were both hand-shaped from aluminum, following a neo-retro enduro aesthetic. The tiny LED light that pokes out the front only acts as a daytime running light, with a PIAA spot, mounted to the left side of the bike, lending a hand.

Out back is a swooping tail section that gives us strong classic Kawasaki vibes. It’s also made from aluminum, as are the ‘side panels,’ one of which is actually the bike’s new electronics box. A solo seat sits up top, with an LED taillight tucked away under the rear cowl.

Custom Triumph Bonneville by Thrive
The seven-spoke wheels actually are from a classic Kawasaki. Measuring 19” at both ends, they were adapted to the Triumph via custom spacers, painted white and wrapped in Pirelli Scorpion Rally tires, chosen for their ride-anywhere appeal. Öhlins rear shocks sit sneakily at the back end of the bike too.

The control area features a new bracket for the OEM speedo, and Brembo brake and clutch controls. The foot pegs and turn signals come from Thrive’s own parts catalog, as do the twin mufflers, which are mounted on custom headers. A custom aluminum sump guard adds a little off-road protection.

Custom Triumph Bonneville by Thrive
The Bonneville Newchurch is a special edition that came out with a very fetching red and white paint scheme. Not wanting to ruin it, Thrive instead painted the new parts in a matching cherry red scheme with black and white details.

It’s a style that we haven’t seen for the venerable Bonneville before—but then again, we’ve learned to expect the unexpected from Thrive. [Thrive Motorcycle | Images by Iqbal Mughniy]

Custom Triumph Bobber by FCR Original
Triumph Bobber by FCR Original One Triumph that’s a little harder to customize than a Bonneville, is the Triumph Bobber. It’s a really good-looking bike out the box, with very little that needs to be removed or tweaked. Your best move is to make a lot of small, clever changes—which is exactly what France’s FCR Original has done here.

Custom Triumph Bobber by FCR Original
FCR Original is known for manufacturing and stocking a wide range of bolt-on parts for various bikes, so they tapped into their own stash for a lot of this Bobber’s upgrades. It features a pair of blacked-out FCR original exhausts and an FCR gas cap, plus LSL handlebars and risers, Behringer controls and a smattering of Motogadget items. The front fender’s another FCR item, while the stock rear fender’s been bobbed as much as possible.

One obvious change is the seat. FCR reshaped it, upholstered it in stylish nubuck leather, and then modified the seat pan with a custom-made cowl. It’s a small detail that makes a big difference.

Custom Triumph Bobber by FCR Original
More subtle are FCR’s changes to the rolling chassis. Take another look, and you’ll spot a set of fully adjustable upside-down forks up front, fitted via custom triple clamps. FCR had the uppers anodized black, while the lowers were treated to a black diamond-like coating.

The team also re-laced the stock hubs to new 17” rims, then spooned on Michelin Road 6 tires. An adjustable shock from 2Win sits under the seat, where you’ll also spot a pair of pod filters and a distinct lack of visible wiring. Lower down, the Triumph’s chain has been swapped out for a belt drive.

Custom Triumph Bobber by FCR Original
FCR cites streetwear and skate culture as the inspiration behind the build, which probably explains the lemon yellow paint job. It’s a refreshing change from the muted tones we often see on bobbers, and hints at how fun this Triumph must be to ride. [Via]

Ducati Monster 600 café racer by Officine GP Design
Ducati Monster 600 by Officine GP Design There are certain Ducati Monster models that either notable, desirable or downright iconic. And the Ducati Monster 600 isn’t one of them. Released in the late 90s as a more affordable entry point into Monster ownership, the only Monster 600’s biggest claim to fame is that it was (and still is) cheap.

That said, there’s nothing cheap about this surprisingly stunning custom Monster 600 from Officine GP Design in Turn, Italy. Run by Luca Pozzato, the shop prides itself on building what it refers to as “only for you” bikes. They’ve built over 100 one-off customs to date, and each one testifies to just how sharp Luca’s eye is.

Ducati Monster 600 café racer by Officine GP Design
The brief for this Monster came from Roberto Passaro, who runs DucatiSpecial’s social media channels. Roberto wanted “a black motorbike that would catch the eye,” and Luca and his crew delivered.

Nicknamed ‘Lucenera,’ the Monster’s transformation started with a custom fairing, fuel tank and tail section, designed to take it from entry-level naked to classy café racer. LED lights are embedded at both ends, with FG Racing clip-ons sit behind the fairing, fitted with a handful of Rizoma parts.

Ducati Monster 600 café racer by Officine GP Design
The Monster 600’s push buttons and clutch housing came from STM, the foot pegs and sprocket cover are Ducabike parts, and the clutch actuator and frame caps are from AEM Factory. The Ducati also wears HP Corse mufflers, Jonich wheels and a full set of Pro-Bolt fasteners.

But it’s the little 600’s livery that truly punches above its weight. It’s finished in a mix of gloss and matte black tones, with a sort of olive-gold hue for the frame and pin-striping.

As an added bonus, Officine GP Design even painted Roberto’s helmet to match—and the bike comes with a matching cover, display carpet, riding suit and watch. Bellissima! [Officine GP Design]

Look the part: The DMD Rivale retro full face helmet

DMD Rivale retro full face motorcycle helmet
Given the rise in popularity of modern classic motorcycles in recent years, it’s only natural that motorcycle gear and apparel would follow suit. Just like most major OEMs have at least a couple of retro-styled bikes in their catalogs, most major gear and helmet companies have at least a couple of retro-styled items to match those bikes. But the Italian company DMD does it differently.

DMD doesn’t just dabble in café racer gear… they live and breathe it. Case in point: the DMD Rivale retro full-face helmet.

DMD Rivale retro full face motorcycle helmet
Based in Bergamo, an impossibly picturesque city in Italy’s alpine Lombardy region, DMD specializes in helmets and apparel. Specifically, helmets and apparel that combine modern materials and manufacturing processes, with all the style and panache of yesteryear.

This family-owned enterprise traces its roots back to 1975 California. While traveling to the US, the patriarch of the family, Amilcare, decided to start a motorcycle gear import and distribution company.

DMD Rivale retro full face motorcycle helmet
Many years later, he and his son, Davide, found themselves in a warehouse filled with archived motorcycle products from the 70s—and an idea was sparked.

Amilcare and Davide reasoned that the market was ripe for a modern remake of one of the helmets that they’d seen there. The neo-retro and new wave custom scenes were only just starting to blossom, and the market for vintage-inspired gear was largely untapped. So, in 2007, DMD was launched, named after Amilcare’s kids; Davide, Michela and Danila.

DMD Rivale retro full face motorcycle helmet
Since then, the company has produced a slew of vintage style helmets—including both open and full face designs, with and without visors. The graphics range from timeless solid colors, to occasional special editions that feature bespoke illustrations from collaborators. Supplementing the brand’s helmets is a full apparel catalog, with jackets, pants, gloves, bandanas and more.

DMD might have been born in the 70s, but the full face Rivale borrows its design from the motorcycle and auto race helmets of the 80s and early 90s. Available in an assortment of solid colors and tasteful graphics, it sports a minimalist aesthetic that’ll look right at home on anything from a classic Ducati Pantah to a modern Triumph Bonneville. Slap a Marlboro or Elf decal on it, and you could easily mistake it for an old racing helmet.

Its shell is sleek and compact, punctuated only by a pair of slim chin vents and very discreet branding. The outer shell uses a fiberglass and carbon kevlar composite, with two shell sizes across the five-size range [XS to XL]. Inside, you’ll find a cushy anti-bacterial lining, with synthetic leather trim to add a touch of class. The liner is removable, washable and even replaceable, plus it’s hella comfortable against your head.

The Rivale ships with a clear visor, but you can order a smoked shield for it too. The visor retainer bolts and guides look and feel solid, requiring an Allen key to remove, while a simple tab at the bottom left of the visor snaps it into place while riding. Although the visor doesn’t have any stops on the way up or down, it’s easy to snap in and out of place with gloves on.

The Rivale also features a padded chin strap with a D-ring closure, and a removable chin curtain. And despite its retro appeal, it meets with the ECE 22.05 standard.

DMD Rivale retro full face motorcycle helmet
If you’re considering getting one, it’s worth noting that the Rivale has a very close-fitting chin bar, and that its ventilation is limited. But those tradeoffs are what make the Rivale look as good as it does (and besides, the chin vents are just sufficient enough to stop the helmet from being stuffy). And it does look good; the off-white paint job is as tasteful as it gets, and every last piece of trim is tidily finished.

It also runs true to size, and won’t tire out your neck, showing a respectable 1,428 grams [3.15 lbs] on our scale. Out on the road, it isn’t quite as quiet as some high-end touring helmets, but it’s aerodynamic enough to adequately mitigate excessive wind noise.

DMD Rivale retro full face motorcycle helmet
DMD used the same process to design and develop the Rivale that they do with all of their helmets, under the guidance of Davide, who acts as the company’s CEO and lead designer. It started out as a sketch, before moving to digital design and simulations. From there, DMD built a prototype and started testing it—including putting it in a wind tunnel.

As a family business, the DMD team is extremely hands-on when it comes to not only helmet design, but testing too. The siblings share a love for motorcycles and travel, which informs and inspires every decision they make.

DMD Rivale retro full face motorcycle helmet
When a new helmet is in prototype mode, they often airbrush or hand-paint it to figure out precisely which direction to go in. And if you’re buying a DMD helmet, you can be sure that it’s been worn and critiqued by the hands that designed it.

Add that experience up, and the Rivale hits the mark for a simple, café racer-appropriate lid. It’s available now directly from DMD, starting at €469 for solid colorways.

Produced in partnership with DMD
