This week’s version of Velocity Learn lives as much as its identify. It begins with an endurance racing-prepped Suzuki GSX-R1000, and ends with a duplicate of an early 1900s land velocity bike. Sitting within the center are a 890 cc KTM filth bike, and a very bonkers Kawasaki Z1 restomod.
Suzuki GSX-R1000 by Group Basic Suzuki Should you’d wish to really feel previous, take into account this: the Suzuki GSX-R1000 K1 was launched over twenty years in the past. Lighter and sooner than its predecessor, it’s thought of by many to be a future traditional. It’s additionally now formally sufficiently old to race within the European Endurance Cup—which is why Group Basic Suzuki has simply prepped one for racing.
Group Basic Suzuki is a staple of the European endurance racing scene, the place they’ve been fielding a highly-tuned Suzuki Katana since 2017. However the guidelines have modified, and the GSX-R1000 is significantly faster. So the Katana is out, and the Gixxer is in.
Group Basic Suzuki’s GSX-R1000 wears a laundry checklist of hop-up components. Beneath the hood lies a freshly-built GSX-R1000 engine, with Yoshimura cams and a full titanium Yoshi exhaust system. A manufacturing facility Suzuki GSX-R750 endurance racer lent the mission its swingarm, and the wheels are from OZ Racing.
The entrance forks are Group Basic Suzuki’s personal design, upgraded with Ok-Tech internals. A Ok-Tech shock props up the rear, whereas Brembo brakes deal with stopping duties.
Among the components used come straight from Suzuki’s Race Elements Programme. It’s an initiative that provides assist and reductions on race-spec components for membership racers within the UK—so weekend warriors can take notes from Group Basic Suzuki to mod their very own contenders. And there’s loads to take notes on.
Wearing Group Basic Suzuki’s signature livery, this GSX-R1000 makes a robust case for the mannequin’s future traditional standing. We are able to’t wait to see it ridden in anger. [More]
KTM ‘890 SX-F’ by JZ Handmade Even should you don’t know Jan Žuži’s identify, you’ve seen his work. He’s the fabricator liable for the jaw-dropping Praga ZS 800 prototype (a indisputable fact that he was solely capable of reveal lately).
Should you want extra proof that the person has expertise, we current this buck wild KTM. Constructed for the 67-year-old Czech off-road racer, Jiří Heiník, this Franken-dirt-bike contains a KTM 890 Duke R engine in a KTM 250 SX-F chassis. And it’s not only for present, both; Jiří plans to race it within the legendary Erzberg Rodeo.
What’s nuts is that the ‘890 SX-F’ appears to be like loads like a inventory KTM enduro bike from a distance… nevertheless it’s actually not. As you’d think about, dropping a twin-cylinder engine right into a slim motocrosser body isn’t precisely a stroll within the park. Jan began by liberating the SX-F’s steering tube from its body, then welded up a brand new body utilizing cut-up items of the unique.
Jan additionally widened the OEM swingarm to accommodate the broader engine. Subsequent, he constructed an aluminum gas tank that ‘hides’ contained in the subframe, a brand new airbox, and a pair of {custom} radiators.
The bike additionally sports activities new wheels and yokes, a {custom} engine guard and shift lever, and new wiring. The titanium exhaust headers are handmade, and terminate in a titanium Akrapovič muffler.
The result’s a very bonkers off-road race bike that makes 120 hp and weighs simply 290 lbs. “It’s gnarly and insane,” says Jan, “however it may well additionally trip surprisingly clean and calm similar to an everyday 250 filth bike. I may think about that with a road-legal plate and supermoto wheels, it might be the bike of the millennium!” [Via]
Kawasaki Z1 by Bull Dock On this planet of iconic Japanese superbike restomods, a handful of retailers function on an entire different stage—and Japan’s Bull Dock is one in every of them. It takes only one have a look at this eye-popping Kawasaki Z1 to know that they’re in a league of their very own.
Constructed with assist from the British suspension model Nitron, the ‘GT-003’ is stacked with top-shelf components, and a few fairly wild mods.
For starters, the engine’s been bumped as much as 1,230 cc, with flowed heads, solid pistons, new valves and Yoshimura cams. Different upgrades embody a set of Yoshimura flat slide carbs, a hydraulically-actuated dry clutch and a bunch of components from Bull Dock’s personal Win McCoy vary.
Given how a lot work went on in and across the engine, the Kawasaki Z1 wanted an exhaust to match. It wears a full titanium system, hand-welded and capped off with a Win McCoy silencer.
Transferring to the chassis, Bull Dock ditched the dual rear shocks for a {custom} mono-shock association. It’s hooked as much as a Win McCoy swingarm, with a custom-specced piggyback shock from Nitron.
The rear suspension setup was designed digitally and examined utilizing software program simulations, to optimize dealing with. Not solely is the rear suspension completely different from inventory, however the body’s been straightened and braced in quite a few locations too.
The entrance finish wears billet yokes and a set of adjustable Nitron right-side-up forks, with a Bitubo steering damper. Between the tweaked entrance finish, and the rigorously designed rear finish, the Z1 now handles miles higher than it did within the 70s.
Cast Lavorante wheels carry down the rotational mass, whereas Pirelli tires supply modern-day grip. The brake system makes use of Brembo calipers with Sunstar discs, and a one-off rear grasp cylinder. A set of Win McCoy rotor fasteners are color-matched to the inexperienced wheels.
After which there’s the bodywork. Utilizing a mixture of OEM-style and {custom} components, inbuilt all the pieces from carbon fiber to strengthened fiberglass, it’s oozing retro superbike steeze—particularly whenever you issue within the audacious livery. [Via]
1909 North London Storage 2.7 Liter J.A.P. The North London Storage was a boutique bike producer that existed in London within the early 1900s. In 1909, they constructed a bike for the racer Will Cook dinner, with a view to setting a brand new land velocity document.
Their components was fairly easy; the present record-holding bike had a 2.5 liter engine, so their bike would use a 2.7 liter J.A.P. V-twin. The constructed a bespoke race bike across the 20 hp J.A.P. motor, able to round 90 km/h [56 mph]. Will Cook dinner took it to Brooklands to make historical past, however the timing gear failed throughout his run and he by no means formally recorded a time; the document stood.
This isn’t that bike, even when it appears to be like precisely prefer it. It’s a trustworthy recreation, constructed by Pavel Malanik—a machinist and engineer in Czechoslovakia with a ardour for bikes made between 1900 and 1910. He’s constructed a handful of replicas now, even going as far as to construct their engines from scratch.
The mission was conceived when Pavel found photographs and historic details about the North London Storage J.A.P., and determined that it was value replicating. Particulars in regards to the bike had been scarce, so he used images to work out the bike’s dimensions, then created drawings to behave as a blueprint.
After a yr of analysis, Pavel started constructing the J.A.P. engine from the bottom up. Every cylinder was machined from a strong block of metal, the cylinders had been bored out, the crankcase’s two halves had been milled out, and the crank- and camshafts had been turned on a lathe. Working one half at a time, Pavel ultimately had a working motor.
Subsequent, he fabricated a body from metal tubing. This was a mammoth activity by itself, because the bike’s authentic design included loads of bracing to compensate for the monstrous engine.
Each single a part of this intriguing bike was made by hand—apart from the Avon tires. When the bike was prepared, Pavel began studying how you can trip it (it’s fairly a handful, as you’d think about), then took it to the observe. You may hit ‘play’ beneath to see how that went. [Via]
