Winning Motolite Details.

Jason Dunns all conquering two stroke Motolite Race Bike

Late 80s Honda RS125 GP bike running gear. Honda CR85 prepared by Col Dunn. Ultra reliable, terrific finishing record. Multi championship winning machine.

Anantomy of a Motolite racer






Motolite with no fairing.
Honda CR85 motor fits snugly in frame. The kick start mechanism casing hump has to be removed (cut off and cover plates welded on) to seal the hole made by removal. Engine plates to accommodate the smaller engine are available as is the expansion box.





Shows how snug the motor is in the frame. Radiator, rear sets and all running gear is standard RS125.

Modifications to Honda CR85 motor to fit in Honda RS125 chassis

Above: Picture of an RS125 motor which shows what's required. Modified CR85 cases will never look that neat though. Being oil tight is all that's required.

If contemplating building a similar Motolite obtaining a rolling chassis is usually not too difficult and CR85 motors are the most plentiful, although a complete bike may need to be purchased to get a motor.
Other two stroke motor options for this versatile chassis would be Yamaha YZ85 (Don't tell club President Ken Lindsay though as he would consider this the ultimate sacrilege!) or the newer KTM 85 engine, it is a lively performer out of the box.
The Motolite class with it's open rules (only capacity rules) is an ideal class for a competitor that want to play with the many variables that open rules allow.

Before embarking on the build ring any of the engineers / tuners that advertise on this website or any Committee member for advice. You can also contact us through the contact form on the website.
