This Bike Function Initially ran on Bike EXIF October 28, 2016. What do you suppose, does it nonetheless maintain up?
We preserve questioning why our inbox is flooded with basic BMWs. Now WalzWerk have offered a clue: you possibly can flip an airhead into absolutely anything.
“We name our BMW collection Schizzo,” says proprietor Marcus Walz, “as a result of it’s schizophrenic what number of potentialities there are to construct up a motorcycle on the identical easy base.”
WaltzWerk know higher than most: they’ve racked up a formidable eleven Schizzo scramblers this 12 months alone. Now they’ve modified path with their first Schizzo cafe racer—primarily based on a 1984 BMW R80 RT Monolever.
At a look, it seems to be a easy machine. However Marcus and his workforce aren’t identified for doing issues in half measures. “Like at all times, we took the bike completely aside and constructed it from the bottom up with about 90% new elements,” he explains.
“We solely re-used the principle body, the engine and transmission case, the wheels and the gasoline tank. The remaining is just about model new. So you possibly can say it’s a model new bike with an outdated title!”
Many of the funds went into the engine. Beginning with a R100 RS mill, WalzWerk put in a 1070cc package from Siebenrock with lighter pistons and cylinders. In addition they added their very own digital ignition, new cylinder heads with greater valves and upgraded valve guides, a racing cam and rods, and a balanced, solid crank shaft. Oh, they usually fettled the carbs too.
A stable spherical of dyno testing and tuning returned a wholesome 82 horses on the rear wheel. That is loads of heft for an outdated airhead—so WalzWerk strengthened the body within the neck and engine mount areas, to assist it cope.
The remainder of the body’s been de-tabbed, and handled to neater rearset and exhaust mounts. There is a new subframe out again—a bolt-on unit designed to look prefer it’s floating, with an LED embedded within the tail.
The fairing and tail piece are one-off models. To create them, the workforce formed unfavourable varieties out of sheet steel, earlier than making optimistic varieties with fiber glass. The ultimate elements had been then shaped with carbon fiber. “That was very difficult,” says Marcus, “however the end result paid off.”
There’s a brand new custom-made bracket to connect the brand new fairing to the prevailing mounting factors on the body. Behind it are a set of Gilles clip-ons, adjustable LSL levers, and a speedo and bar-end flip alerts from Motogadget.
The entrance suspension is from a BMW K100—rebuilt with NOS fork tubes and legs, and lowered 70mm with progressive springs from Wilbers. The triple tree is NOS too, however WalzWerk cleaned it up on their mill, and closed the outdated handlebar mount holes with aluminum plugs.
Braking upgrades embody a Brembo grasp cylinder from a Ducati Monster, together with two-piston calipers and drilled chrome steel rotors. To maintain issues uber-clean, the brake line runs down by the steering neck.
There’s an adjustable YSS shock preserving the again in verify, and a set of Tarozzi rear-sets. A brilliant-light Lithium-ion battery is tucked away in a custom-made field underneath the transmission.
Given the variety of BMWs they construct, it’s made financial sense for WalzWerk to develop a proprietary wiring harness—full with fashionable relays and connectors. “It was loads of work to do that,” says Marcus, “however in the long run it saves a lot time, as an alternative of reducing and lowering the inventory harness and nonetheless having the outdated wires and relay sorts.”
To get the exhaust system excellent, WalzWerk teamed up with fellow Germans KessTech. They’re identified for making Harley exhausts with adjustable quantity—a function that Marcus wished on the Schizzo.
“The brand new proprietor of the bike lives in Bavaria,” he explains, “and the Bavarian cops are very unusual when the bike is to loud—even whether it is an outdated bike. However now you possibly can shut the flaps within the muffler: No issues in Bavaria!”
The exhaust system’s been ceramic coated in satin black, together with the ultimate drive. Every part from the engine to the wheels and body, has been powder-coated, painted or cleaned up.
And despite the fact that the gas tank seems to be outdated, it has been given some love. WalzWerk welded in a bit close to the seat junction to ‘shut’ the tunnel, and added a Monza-style gasoline cap. The worn out paint job is all-new, executed by Chikos Pinstriping in Pforzheim.
We simply had one query for Marcus: why Firestone Champion Deluxe tires on a 82HP boxer?
“Many of the bikes I’ve constructed I promote with two units of wheels,” he explains. “For the basic trip within the metropolis or within the city space you possibly can select the wheel set with the Firestones—and for prolonged excursions or lengthy distance rides, you possibly can throw on the opposite wheel set with the Continental Highway Assault tires.”
Honest sufficient.
Judging by how a lot WalzWerk have poured into this construct, we would guesstimate the value in the identical ballpark as BMW’s upcoming R nineT Racer. We all know which one we would decide although… how about you?
