Wossner Pistons?
« on: January 02, 2015, 05:03:35 PM »
I'm preparing to build the motor on my current project, '74 Kaw H1 500, and the Triples forum is highly recommending Wossner pistons.

They're a forged piston made in Germany, and piston skirts come with a Moly coating to reduce friction and help during break in.

Do you guys have any experiences with them to share?   Thanks

Looks like not too popular with our SOHC crowd, guess that's why I haven't heard of them.  Just one with my RD350 buddy, he is also recommending them.  Need to measure the cylinders and determine what size to order, most likely +.5mm.

Thanks for the comments.
