125cc YX Engine Classic Start for Dirt Bike, Pit Bike
The 125cc YX engine is built to withstand the rigors of off-road competition. Its durability is essential to ensure consistent performance during long racing sessions and intensive training.
Easy maintenance: Another advantage of this engine is its ease of maintenance. With a simple and well-thought-out design, regular maintenance is easy to perform, allowing riders to spend less time in the garage and more time on the track.
Versatility: Although this engine is mainly used in off-road racing, its versatility also allows it to adapt to other applications such as pit bikes and recreational motorcycles.
Power: 10hp
Bore: 54mm
Speed: 4-speed manual N1234
Cast iron cylinder
Attention: Arrival without kick starter, without shifter, and without intake pipe
(Many replicas exist for this engine, we guarantee the official origin from the YX factory and warn against copies present on the market)
Compatible with all brands of dirt bike, pit bike (YCF / GUNSHOT / CRZ / PISTERPRO / ORION...)
Starting advice: We recommend an engine oil change at startup as well as a break-in of 3 full tanks at half throttle. All settings are done at the factory but a valve adjustment may be necessary during the break-in if you observe kickback/compression returns or at the exhaust valve (Timing: 0.05 Intake / 0.08 Exhaust)
