They guys at Motorsport provided the best customer service in the world. I will always going to shop from their website. This kind of customer service is what we need in America. The owner of this company is very smart how he/she runs this business. Keep up a good job guys.

Now let me move on to the piston. I love the quality of the product. It looks really well built but I have not taken my bike for a ride yet. It is too hot here in California, where we can ride. In 2 months or so then I can tell if it holds up to it name.

Great product

the whole top end only took a few hours and was up and running. Thing sounds great and the powerband is awesome!! I haven't had it in for long so the durability has yet to be determined but so far so good.

Feel the power

Put a fresh top end on my sons kx100. Stock bore. Real easy to install. He felt the difference in power immediately. Front wheel easily comes up with no clutch pop. Highly recommended.

Nothing but the best.

Best way to go if you prefer to run a forged piston in your 2 stroke. Great fit, finish and quality.

Pro lite piston 2 stroke

Put one in my kids yz85. With polishing the exhaust port
and roughing up intake ports.and tunnel,it made a big
difference on bottom end power.

Just what you expect from Wiseco

Just installed the Wiseco standard bore piston kit in my 2004 RM125. It was fairly easy to install, and the quality of the product is evident as soon as you take it out of the box. My bike is back to its old snappy, revy self again! Thanks Wiseco, and thanks MotoSport!

Good Piston

I just installed this piston in my 04 CR250. It is alive and fast as ever. Everything went together well and was easy to install. The only complaint is you get a little piston slap every once and a while, but that is it. The bike is fast and runs great. As always customer service at motosport.com is awesome.

I put this in my bike and rode it for 3 seasons. I then sold the bike to a friend and he still hasn't touched the top end. (we don't race) but the bike is still running strong. Great product

Q: What size piston do I need?

My piston says 5845a on it and is not the stock bore size what size do I need? .40 over?

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.

Q: Just got this for my stock cr85, do i need to drill lubrication holes like it says or is it ready to be put in as is?

A: If the cylinder has an exhaust port bridge going across the center of port, then yes you will need the holes. If it just has a full size hole for the exhaust port with no bridge in between, then you do not need to drill holes.
