Some people were interested to see how much the Yamaham weighs and I have now had the suspension professionally set up and the corner-weights adjusted by RH Racing.
Brief spec is: live-axle chassis, ital axle (drums, LSD), CX-R one-piece wheels (6" front and 7" rear), CR500 tyres, carbed R1 engine (no dry-sump, foam filter), R1 ali radiator/fan, electronic & manual gearchange mechs, 2-piece prop with centre-bearing and TRT, no reverse, home-made loom, no weather gear, CC half-doors, carbon aeroscreen & dash, digidash instead of clocks, GRP front & rear wings, GRP Tilletts with box section ali runners, FIA bar, stainless 4-2-1 manifold with baffled bike can, alloy front hubs, alloy dampers, alloy big-brakes, ali boot floor........
The numbers:
*arrowright*With 75kg ballast in the driver's seat and 25 litres of fuel and all other fluids = 480kg
*arrowright*Remove driver = 405kg
*arrowright*Remove fuel = 385kg
Front:Rear weight distribution = 42%:58% (with 25l fuel in tank and driver).
Approx. 100kg on each of the fronts (with driver), with the rear taking the imbalance.
Extremely pleased with the final weight - should make for power:weight of around 415 BHP/tonne (based on estimated 160BHP and the sans fuel weight). Yet to test out the new setup on road/track......
