All 2st Top-End Rebuild Kits

Getting ready to do a top-end rebuild and was wanting opinions on the different brands. I've always used Wiesco but have been thinking about trying an Athena kit. Your opinion counts!

go with wiseco or wossner.i prefer wossner (like the name better).

Thanks Joe, never heard of Wosser. Are they in your hemisphere?

I think that Athena and Wossner are the same company. I bought an Athena kit for a KX I had and it contained a Wossner piston.

we have had better luck with Wossner pistons than Wiesco for that application.they are priced well also.dan

David - My WR250 had a Woosner piston in it when I bought the bike, with a lot of hours and it still held up. - They're forged, coated and have two rings. They cost about 120€ for the WR250 where as the Athena kit is 165€. Both available on-line or through most bike dealers. Woosner rings are 22€/set. - I'll be using the Woosner kit when I next reubild the top end.

Wossner makes pistons for Athena and l swear by a wossner piston....96 WR360 and have had 120+hrs out of a wossner piston.

You pay a bit more but the quality and strength IMO, is superior to a Wiseco (although their forged units are very good).
