It is designed for 883-to-1200 conversions, where the cylinders must be bored to the new dimensions before installation. Riders choose this kit for a big-bore upgrade that pairs forged construction with a moderate compression increase for a noticeable performance gain.\u003c\/p\u003e\n\u003cp style=\"line-height:1.65;\"\u003eThe forged piston crown provides strength to handle the added demands of a larger displacement. ArmorGlide skirt coating reduces friction and improves scuff resistance. Force-fed pin oiling delivers lubrication to the piston pin, supporting reliable operation over time. The 9.5:1 compression ratio is described as a moderate step up that works with stock heads and many bolt-on performance parts.\u003c\/p\u003e\n\u003cp style=\"line-height:1.65;\"\u003eAlways ensure the cylinders are bored and honed to the specifications for these pistons to achieve optimal performance and longevity.
