1989 Yamaha:FZR750R OW01
This is a brand new, never started World Superbike.
Yamaha introduced its FZR750R OW01 to the motorcycling public in time for the 1989 season. The OW01 was ahead of its time, the frame was developed from the FZ750R but the aluminium was of much higher quality, so much so it wasn't even anodised. It got an Öhlins rear shock with remote hydraulic preload adjuster, a six-speed gearbox, loads of magnesium and titanium parts, and a proper race motor. The OW01 has an inline-four engine with a five-valve head (that's three intake and two exhaust, 20 valves in total), but with a difference - it was built for the race track. The pistons only had two rings, the con-rods were made of titanium, it had a close ratio gearbox, a four-butterfly EXUP valve and flat-slide carbs. This was no road bike engine: indeed the OW01 was one of the first racers you could buy off the shelf for road use.
