Our pistons are very good quality and come complete with rings, gudgeon pins and cir-clips. We have been using these pistons in our own bikes, engine builds, restorations and sold countless sets all around the world for the last 10 years.

We use the low 7:1 pistons in all of our engine builds and restorations as today’s low octane fuels are not what they used to be. Also, being low compression, this stops the issues of pinking and makes the bike a lot easier to start with lower compression. When using these pistons it makes no different to the power of the bike in fact we are using a set of these pistons in one of our T110 race bikes.

When selecting the pistons please ensure you select the correct Piston Ratio. PLEASE SELECT BELOW:
