Millennium Technologies has just made it easier to do your top end. Based on the huge success of our cylinder exchange program we are offering top-end parts in a kit form. It doesn’t matter if you need a kit for a dirt bike, ATV/UTV, street bike, snowmobile, watercraft—we handle all powersports. Not only are they matched to the cylinder they are a significant savings over buying them separately! We offer many brands of pistons, such as Wiseco, Vertex, Wössner, JE and CP, either cast or forged. The cast pistons are direct OEM replacements where the forged pistons will be directed towards the more performance minded. Top end gaskets are also available and add to the savings. Let us do the leg work and get the parts you need.
