ProX pistons are forged and precision machined on the latest, state of the art CNC equipment. The same low-expansion, low-friction piston alloy is used as is used for all major Japanese engine manufacturers. ProX Piston Kits are a first class solution to replace the original piston in your Beta!
Coated for ultimate performance
Most of the ProX pistons come with a coating. Our OEM style Tin coated pistons assist the wear in process when you just started the bike. We have developed a new skirt coating that not only assists the wear in process, but also helps reducing friction after the wear in. The black coating is made from a delicate mix of materials and will increase performance.
ProX pistons for Nicasil/plated cylinders
The latest cylinders are plated by a Nicasil plating. Therefore we offer a wide range of ProX pistons in A, B, C sizes.
Please check which size kit you need by removing the power valve cover on the left side of the cylinder, you'll find the size designation on the cylinder inside that chamber.
Note: This piston is not coated as pictured, and as it is forged it does weigh a little more than the stocker and will therefore cause a bit more vibration at the bars.
