Chief creator Rolf Andersson used a Rover V8 engine in one of his creations and several other such custom built bikes are also ready for you. Although these bikes looks much smaller than the Boss Hoss bikes, something like the DRYSDALE, in power transmission, they are at par. Rolf has a preferance for GM / Rover engine for the reason that is has variable size, weight and comes in many engine sizes ranging from 3500-5200cc. He uses a lot of aluminum as he says its easily weldable. You can get both longitudinal and transverse engine set-ups.
The bikes are all single speed and use an electric/hydraulic clutch setup. He also offers a primary drive for Rover V8s in the transverse configuration.
The PROTOTYPE project started in March 2001 with the goal to construct and build a motorcycle in the size of a regular motorcycle but with a v8 car engine. The frame is a split frame made from 2391C quality tubing and it is shaped in a cnc Herber bender with internal clamp and the front end came from a Suzuki GSX 1100 F. Everything is TIG welded for high quality. In this particular model, the clutch was the biggest challenge and afetra lot of experimenting, he settled for a electric-hydraulic system which has a one speed transmission. Amazingly this mammoth cruises at 110 kph @3200 rpm and has a top speed of 200 kph @5700 rpm. This moster do gulp a lot as expected and it gives you 10 km for a liter, not really bad then! With a 15 liter tank, you can only go for 150km, so think well before you take the expedition. He has already tested this prototype for 21000 km, all trouble free during the past 2 seasons. It's construction time was 3 years.
