It’s works great if you know how to put it back

Well the kits worked great! The third time I did it because I had the piston in back words with the spring down. Now i disassembled it with piston backwards mind you this is the first time replacing it. I wish there was atleast a diagram to go with it because I couldn’t pull up instructions or anything but thankfully I had a faint idea of what to do. Brakes actually work now and would totally recommend this product.

Fit right and good value.

It’s hard to find parts for older bikes. This kit fit right and was priced right. 4 stars for now, we’ll see how it holds up.

Incorrect fitment

I purchased a complete rebuild kit for the front brakes on my KTM. Along with poorly fitting all balls caliper o rings, the plunger for the master cylinder was several MM too long. It would not allow fluid to move past the master cylinder.

Quality Parts

I purchased this kit for an older RM85. The kit did not include an actual new piston, but all seals, washers, etc were present and of high quality.
Turned out I did not actually need to rebuild my master cylinder (there was a tiny bit of dirt in the fluid return port in the reservoir that I missed) but the price is such that I wasn't too put out over it, and I won't be worrying about the brakes for a long time!

Easy to work with gets the job done

If I die due to front brake failure it was these guy's fault, but that hasn't happened. Will update if it does

2014 KTM 250xc - easy to install, works great. Be sure to clean cylinder and flush brake line for optimum performance.

Good quality. Delivered Early!

My 2007 Grizz had been sitting for quite some time and brake fluid was NASTY! Changed fluid and rebuilt rear caliper and master cylinder. Parts for both were bought from Motosport. The reason for only 4 stars is that the master cylinder kit did not contain the 2 screws for the reservoir cap. Really could have used the replacements. Other than that the parts were excellent! The early delivery was a pleasant surprise!
