Product Name
ProX Beta 300RR Piston Kit
[19-7393?]
price$184.99
Product Description
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 about 20 grams more than the stocker and will therefore cause a bit more vibration at the bars. Also, ProX does not list anything for the XTrainer but Beta uses the same piston kit in both machines so this kit should work for it as well.

Produced by ProX of the Netherlands
