Hello guys. I'm currently shopping for pre 95 DR650 pistons here is Australia. I'm wondering if anyone has used Wossner Pistons ? They are cheaper than the Wiseco options and come in high comp and other types.
I'll probably just stick with the Wiseco but just curious if anyone has experience with other brands.

Ok thanks Lancer.

All looks OK to me.  

At a total weight of 491 grams, it won't be a shaker. The compression height will not pose a problem.  I assume it is a pop-top with a dome volume of 6.1 cc so the compression ratio will be under 10:1. It shouldn't be a problem finding fuel with sufficient octane.

You still should do clay checks to verify adequate valve-to-piston clearance.  Given the compression height I suspect that you will have plenty of room but it's always better to be safe than sorry.

Once you get that piston, howzabout posting some pics.  If it comes with any instructions, would also be nice if you could post those too.  I'm particularly interested in the ring set and recommended running clearance.  Appreciate any info you can share with us.
