This is the factory Yamaha YZR 0WE0 ridden by Kevin Magee to second place in the 1992 500cc All Japan Championship, where Magee finished behind fellow Aussie Daryl Beattie on an NSR Honda. Peter Goddard had won the Championship for Yamaha on the 0WD3 the previous year, so it was a good time for Aussie riders!

The owner has bodywork in both the 0088 AJC colours (seen in the two images of Kevin demoing the bike), as well as in 1989 Team Roberts Lucky Strike colours.

The bike is fairly unusual for the period in retaining the factory frame. Most factory YZRs, even the GP teams, were using the ROC chassis.

Yamaha experimented with various firing orders during the year (180º was the normal) with a 0-90º “big bang” motor being used from half way through the GP season. Kevin preferred a 90-270º firing order however – but this wasn’t used in GPs. The output of 160 hp was 5 hp up on the 1991 0WD3.

This is the 500cc Suzuki RGV/XR88 that Nobuatsu (Nobby) Aoki raced in the final three races of the 1998 season. His best finish was a fourth in the Madrid GP, with an overall ninth position in the 1998 Grand Prix Motorcycle Road Race Championship.

Suzuki tried several different chassis during the year, this being the final version. Compared to the previous year’s bike, the main motor change was the use of Keihin carburettors rather than Mikunis.

The V4 used twin crankshafts at an 80º angle with both reed and exhaust valves. Output was 180 hp with a wet weight of 135 kg, while top speed was 320 km/h.

Suzuki’s RGV500 saw success in the hands of a number of riders, including Kevin Schwantz who claimed the 1993 World Championship, and raced an RGV500 from 1987 through to 1995, with other notable placings including three fourths, a third and a second in the championship during this period.

Daryl Beattie also campaigned an RGV500 to second in the championship in 1995. Beattie was on course to win the 500cc Grand Prix World Championship in 1995, but a crash at Assen proved costly with Mick Doohan going on to claim the crown for Honda.
