AMAZING!

Comments On Apr 25, 2015:I blew a piston in my bike and was skeptical of buying a low priced piston but it performs so much better than a $150 piston. I highly recommend it!

Wiseco Piston Kit

Comments On Feb 03, 2015:Wiseco makes a very durable and reliable piston and ring kits, we have used them in a lot of our customers rebuilds all with great results.All the clearances are always perfect, and rings only need minimal filling. Just wish wiseco would drill the holes in the pistons for some of the 2-strokes.

Good piston

Comments On Feb 03, 2015:This is a very good quality piston. But if you have a stock bore size this will not fit your application. I ride a ktm so I can only speak for that app. You will have to find a piston with a 96.94-96.96mm piston and this is a 97.00mm.
