The cylinder is the heart of your bike – it's where all the power you have at your disposal is made. As a rule, modern engines such as Yamaha's YI 4 are very tough and built to last. Even so, a part on your cylinder can fail and you'll need a replacement – the cylinder gasket, for example, goes from time to time. When that happens, get it repaired quickly: a faulty cylinder doesn't just cost you power on the road, in the worst case it can also lead to bigger (and more expensive) damage elsewhere in the engine.
As well as replacement pistons, you'll also find replicas of the original 125cc cylinders here, so you can restore your bike to its "factory spec" at any time.
On top of that, we offer a selection of tuning packs and big bore cylinders in sizes from 125cc up to 183cc – so you can boost the performance of your 125 for the track.
