Better than other aftermarket options

Quality materials, no leaks after install. Looks substantially better in quality than other cheaper aftermarket gaskets. Would recommend and definitely will buy again.

Great design

The plugs look great and fit great. If your about the small details on your bike these plugs are for you. The Allen head replaced my flat bladed plugs, I feel way better about getting them in and out.

Great piston

Great kit.

I needed a new seal and this did the job. The kit fit perfectly in my KTM and was easy to install. You can find the seal alone much cheaper, but it doesn't include the O-ring or other parts that are needed to rebuild the countershaft seal correctly. I have used this kit on two of my bikes and they haven't leaked yet.

1998 cr 250r

This rebuild kit is very easy to install, but it has it's doubts with me. I had it put on my dirt bike for 3 weeks and after 3 weeks of riding it messed up, the gaskets fit perfect, and I had no problems with installation.
