This kit will fit all Kawasaki 1200cc ULTRA 150/ STXR 1200 engines. WSM and Pro-X Pistons are a full cast and come with Rik Japanese high performance rings. Wiseco pistons are forged and use Wiseco high performance rings only. Order Std size pistons if you are only honing your cylinders. If you have more damage to the bore and the cylinder will not clean up at STD. Please order the correct over size piston kit. Be sure to inspect your sleeves carefully for heavy scoring chipping and cracks. Remember 1.00mm is .040", this means you will only be able to cut up to .020 into your cylinder wall for it to clean up for finish honing. If you have damages deeper then this you will need the cylinder sleeve replaced and bored to finish size. We also offer top end rebuild kits with cylinder already machined ready to install on a core exchange basis.
