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
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.
For aircooled motors a
capacity of 111cc is allowed.
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
