Exceeded my expectations

First top end since I’ve owned my bike. Showed up on time, straightforward install. Feels like a brand new bike. Haven’t had the time to really ride on it yet, so I can’t comment on durability. Seems fine.

Great Power!

I bought this piston when I had my cylinder re-nikasiled for my 2004 KX 125. It has a noticeable power difference and is running strong. I recommend this piston for anybody rebuilding a two stroke

A: If you are just replacing the piston, then you need to first know the bore of the cylinder. This can be done by using a bore gauge to find the diameter or by reading the owner’s manual to find the bore specifications. Ultimately, the bore should be measured for the best possible results. After the diameter is known, then you can pick which size piston will work best in your cylinder. Remember to maintain about a 0.05mm (0.002”) piston to cylinder clearance, depending on application. If you are having a cylinder re-plated, then you will want to choose a piston of the OE bore size (an A or B size is probably best). When you send the piston and cylinder away to get re-plated, the plating facility will match the cylinder bore to piston diameter. If you have a cast iron bore cylinder and you are sending the piston and cylinder off to a machinist to be bored out, then you will want a piston that is oversized from the current diameter. For example: If your current bore is 64.00mm, then you will want to choose a 64.50mm or similar oversized piston. The machinist boring the cylinder will bore and hone the cylinder to match the piston size. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.
