throttle response is much improved on rmz 450 2009 with this piston together with a Hot rod crank, the finish of the piston is also very nice.
the ring enclosed in wiseco packet was the wrong size! way too small. we had to purchase correct ring locally. maybe wiseco's fault,all else was up to your usual excellent standard.

First time doing 2 stroke topend. It was easier than I thought it would be .The kit had all parts needed, and all fit perfectly. Have used Wiseco pistons in past and lasted very well.

WOW! look here folks this wiseco piston and ring is amazing. It made a fast MX raceing bike even faster.And Trevor (salesman) at bto sports makes this product even better. So look here if you need this part are any other parts ask to speak to TREVOR and he will make your purchase the best purchase you will ever experience . Thank you Trevor for you help for getting the job done and getting back in the show./
