PISTONS- Dont let anyone tell you the 85mm 860 piston is not reliable and cracks or breaks off the skirts. Thats a lie. We use the best Japanese pistons availible in the world. With proper silicone content and proper piston clearance it will last 5000 miles no problem. We had some put on 3300 miles in one season. Some shops are using a different 85mm piston or a off shore made piston with improper silicone ratings and have the piston clearance set up wrong. So then any piston would crack. Just a gimmick to make you buy there kits. Would you rather have a 872 kit with an off shore piston? not me.

No hp gain with .5mm bigger piston, changes port shapes lose power, weaker cylinder skirts, an offshore piston and little porting.
