1989 Honda RC250M
1989 250 World Champion
Jean Michel Bayle's 1989 250 world championship Honda
A special HRC frame, works Showa suspension components, HRC engine, HRC magnesium wheels , works Nissin brakes, HRC triple clamps and titanium fasteners are just some of the components that seperate this HRC factory special from the standard 1989 CR250.
Right behind that little blue cover at the front of the engine, powervalve springs could be inter-changed to engage at different rpm's.
According to former team manager Dave Arnold this engine design was the best 250 that Honda ever built. Even the standard looking carb is a special "NT7" model.
The HRC cylinders look like jewelry. There were different configurations to choose from depending what type of power the rider wanted.
Hard to believe that each HRC chankshaft was about $10,000.00. Those crank wheels are not billet, they are made from several pieces specially weighted.
Bayle's mechanic engraved each cylinder for each GP it was used in. CS = Czechoslovakia, N = Netherlands, F = France. The U after CS and N signify a win for those particular GP's. We also have the spare engine with Venezuala, US and German GP's engraved in the cylinder. Pretty cool.
Crankcases are matched and numbered.
Special linkage providing a much different leverage ratio than stock. Linkage bolts were HRC steel items. Notice the beefed up frame and welded on skid plate.
To control the bike, Bayle would often ride the rear brake. He would get the brakes so hot that the fluid would actually start to boil. The air duct was an HRC effort to cool down the rear brake. Not many photos show Bayle using this. Instead he normally ran the rear rotor open.
Jean Michel Bayle's 250 world championship bike sits today unrestored as he last rode it.
