Racing utgaven

RR Racing 125 cc 2-stroke
The RR Racing 125 cc 2-stroke is a stunning achievement: in addition to all the above it boasts a suspension system expressly calibrated for this engine displacement and a new engine configuration.
Same front and rear suspension as the larger Racing models.
New cylinder, with modified exhaust port and timing charts.
New exhaust flange.
New exhaust valve system and new boosters.
New clutch cover with air bleed system to give the clutch improved feel, a modified oil filler cap position.
New clutch basket.
New expansion chamber.

Improved low-rev power delivery combined with greater high-rev acceleration, resulting in better performance across the rev range and more linear, manageable power output. The outcome is a considerably broader riding range, a crucial feature on a small-displacement engine.
