autoevolution

Segment: Trial

Without losing that Gas Gas trial and off-road character, the new Trial School is adapted to a level less demanding than that of the professionals by offering only one size of engine: a 125 cc two-stroke.

An engine size that helps a rider get on well with the bike without unpleasant surprises for any riders regardless of ability.
