Turning a classic inline-four Japanese motorcycle into a modern custom doesn’t sound like the easiest task, but the results can be truly satisfying. Just take a look at this 1976 Kawasaki Z900 that Spanish custom builder La Perra Bikes recently finished.
At its base, the bike remains the same, so the low bars and black wire wheels, Ohlins inverted forks, Brembo radial brake calipers as well as the wavy Galfer brake rotors help bring it back through the living. Once there, the chopped exhaust should make sure everyone hears it roar.
All in all, this looks like a short way from classic to custom, but it is the black and gold combination that really makes a striking difference.
A simple look at this street tracker is enough for one to think this is a rather expensive project bike and, considering the work and dedication that went into it, there’s nothing wrong with thinking that. But the truth is that Ken Fontenot and the crew at Cycle Sports in Houston, Texas started from a 1975 XS650 rolling chassis that was rusting outside their shop for the past decade and a half. They’ve restored it and used other parts from around the shop to turn it into a fully-functional motorcycle worthy of the checker flag. In the end, the project took six months and under $1800 worth of parts to complete, so it is a winner from the start. Just click past the break for the official description.
Turning the BMW S1000RR into an 8.49-second, 158.46mph quarter mile drag bike can sound like an immense task at first, but considering the German superbike’s incredible tuning potential and the ambition of Brock’s Performance, we are actually talking facts here.
This Beemer sends 203hp and 80lb/ft of torque to the rear wheel – a new stock bikes record – and we’re not forgetting anything when saying that the only changes made to this incredibly fast drag bike consist in external bolt-ons in the form of a full exhaust system and Dynojet ECU, BST carbon wheels, MacIntosh extended swingarm and lowered suspension.
The bike will compete in the AMA Dragbike Supersport class, but only after receiving nitrous injection. Hit the jump to see it in action.
There are custom bikes and then there are amazing custom bikes. This one fits in the second category from obvious reasons. It is a Harley-Davidson customized by Horst Dzhangmen in a unique way during three long years. Long story short, all parts were cut in the form of hexagon, apart from the Shovelhead 1340 cc engine, transmission and modified frame, which are all original H-D parts.
Looking for a reason to why would someone spend that amount of time handcrafting parts for such a bike? No special reason. This is just another way to stand out.
This eye-catching bobber is a personal project of Richard Dunn and it actually started from a 1975 Harley-Davidson Sportster. When he bought the bike, it had all of its original parts on (apart from a weld-on hardtail), so it was just a matter of restoring, reshaping or upgrading the different components that now turn it into a bobber.
Featuring 3-inch lower suspension supporting the original 7-spoke mag wheels as well as a new generation Sportster fuel tank and a custom oil tank, this bike turns from old school into modern. The bars, which are bolted on H-D risers, were supplied by Biltwell Keystone, while Front Street Cycle sent in the rear fender and Baas Metal Craft the thin seat. This last piece is actually described as being “wrapped with foam and some saddle cowhide with a tight stitch around the perimeter,” just so you’ll see the attention to details that this thing required.
Apart from the main parts mentioned above, Dunn’s blood, sweat and tears helped at making the old H-D Sportster look and perform like a one-of-a-kind bobber that is best represented by these gorgeous pictures.
The Z2/750RS was one of Kawasaki’s highly appreciated inline-four nakeds and made the subject of many customization projects over the years and, as we have recently come to find, it can still work its magic. Modified by the Kouga branch of the Sanctuary workshop, this precise exemplar apparently retains most of its original features, but it is brought up to date especially in what the chassis is concerned.
Now built around a powdercoated and reinforced frame and featuring Yamaha XJR1200 suspension as well as Brembo brakes, the upgraded Kawi Z2 should handle much better and come to a hault almost instantaneously. Also, thanks to the Yoshimura-tuned Mikuni TMR-MJN38 carburetion and Nitro Racing exhaust with titanium silencers, the blueprinted and balanced engine that originally developed 69bhp at 9000rpm now responds better to acceleration and sounds racy.
Overall, this is a clean looking bike which, despite having a few good years on its back, only needed a quick upgrade in order to keep up with its modern siblings from most points of view. That’s why we love Japanese bikes so much.
Although it looks like a whole new British bike, this is actually LSL’s Triumph Bonneville ‘Tridays’ Limited edition café racer that the German accessories and customizing specialists have built for the three-day Triumph motorcycle reunion held in Neukirchen, Austria this year from 25-27th of June.
Starting from a 2010 Bonneville , the LSL team has painted the alloy wheels in black and brought in a Remus exhaust, YSS shocks, new instrumentation, ace bars, racer-style seat and polished alloy mudguards, just to name a few of the bike’s distinctive features.
LSL will only build twenty such units and plans on selling them for $16,445 (€12,950). The price also includes a package trip to the Tridays festival. Visit the Tridays website for more information.
When former NASA engineer Casey Stevenson was in the market for a light, economical and enjoyable motorcycle to cruise the LA streets on, he came to find that there are no such bikes being currently made. So he considered turning a Suzuki S40 into a café racer and ended up creating the Ryca CS-1, a 650cc, air-cooled, single cylinder cafe racer prototype. Later, he thought at a way of turning his idea into money, so he founded Ryca Motors, the shop where they turn any Suzuki S40 or Savage model into veritable café racers.
The production version of the Ryca CS-1 features the middleweight single-cylinder engine and a five-speed tranny and returns 60 mpg. Café racer goodies such as the custom low profile tank with integrated keyswitch / indicator panel, fiberglass seat and side covers as well as rearsets with custom mounting bracket and hardware and aluminum clip-ons give the bike its unique look.
Because the original bike’s engine and chassis don’t require significant changes, Ryca Motors also offers a custom parts and accessories kit that owners can buy and install themselves. Click past the break to read about the four different possibilities of getting yourself on one of these and also what the kit includes.
The Triumph Bonneville was the subject of infinite customization projects during the past decades and it seems that there’s always found a new way of turning GB’s iconic motorcycle into a better ride. Madame Bonnie represents such a project, but it comes from Italy, where Triumph specialists Pettinari have tricked it out.
No bike can be called a Bonnie unless the parallel-twin engine is present, so the Milan-based tuners retained the stock engine, but fitted it with 39mm Keihin CR racing carbs, a high performance air filter and a free-flow exhaust. These parts allow the motor to spin easier and sound much more aggressive.
Still, the main focus was on handling, so Madame Bonnie loses its stock suspension for Showa forks and Öhlins rear shocks. Also at the rear, a boxed aluminum swingarm was added. In the end, braking performance was significantly increased by adding Street Triple twin 310 mm front discs and Nissin calipers.
Surely, this custom retains its classy look, but technically it is a step further than anything going off the production line in Hinckley, England.
Take a look at this bike and you’ll most likely have troubles recognizing it as being a Triumph Speed Triple (at least we did), much less uncover the special features that made the transformation into custom possible. The bike was customized by Austrian Triumph specialist Julian Schneider for his own use on the twisties of the Austrian Alps.
Schneider, who is actually a fan of New Zealand motorcycle racer and land speed record holder Burt Munro, has actually called his bike the Burt Munro Edition. Although it won’t set any records as it is powered by the original engine, which only got some intake modifications and a Supertrapp exhaust, this Triumph should now handle and feel much sweeter considering the great number of aftermarket parts. It features full Ohlins suspensions and a steering damper, Marchesini magnesium wheels and a Beringer brake system. Also, the LSL bars, footrests and headlight as well as the Magura brake and clutch controls together with the several other Rizoma parts contribute at turning this into a completely different ride.
Overall, the bike looks like a modern café racer and the red/black with gold stripes and rims looks just striking.
