The new generation of 50cc engine from the YX factory. We had a selection of horizontal 4-stroke 50cc engines arrive in our warehouse, they were all installed into several identical motorcycles and tested for acceleration and top speed, The YX 50cc came out leaps and bounds above the competitors, easily beating the Lifan, Zongshen and the GN, we do jot have the exact bhp but do know this is a great and powerful engine given the low displacement of a 50cc engine.
The YX 50 engine is one of the most reliable learner legal horizontal lay flat engines on the market.
Fitted as standard with a wider ratio gearbox for increased top speed and long term reliability also complimented with easy starting – coming with both kick and electric start.
Why are our engines different to other sellers engines?
Other seller engines:
Engines are sold boxed, un-opened and unchecked and with no adjustments carried out which if left unchecked could cause potential problems and furthermore serious damage.
We carry out a full inspection to ensure all components are present and make all adjustments “Which are always required” to timing and valve clearance settings. We drain the transport oil which is not suitable to use for running your engine.
What does this mean for me?
This means your engine can be fitted straight into your bike with the peace of mind that a professional technician has set it up to run perfectly for its breaking in period, which is the most important point of the engines life……. just add good quality 10w/40 semi synthetic motorcycle oil and away you go.
