These bearing were installed into a '17 KTM when the stockers failed. They lasted a total of 12 hours before they failed. Upon removal of the bearing and it's dust cover revealing zero grease inside the bearing. These might be great if when their new you remove the dust cover and grease them. So I'll pass on these and just pay a little more to get factory KTM bearings.

I bought these bearings from Motosport because they met the specifications for my motorcycle. Needed ABEC 3 accuracy and C0 fit, not C3 motor bearing fit which is industry standard. I tried some local bearing houses but they couldn't provide the correct fit and tolerance per spec. BMW wanted 6 times the price. It was a no brainer for me. Bearings are a commodity very familiar to me, sold them for 35 years and know what I'm looking for.
Only time will tell how the kit does.
I have these bearing installed in my 400ex hubs, but haven't ridden them yet. The bearings were a tight fit, which is desirable, putting them in the freezer overnight prior to installation make it go a little easier.
Got these for my 2000 ktm 25sx easy to install so far they are working great I'd for sure put a little extra grease in them they don't have very much from the factory
I put these in replacing the original OEM bearings after 33k miles . These went in with out any complications seemed to work great rode about 30 miles in the rain, hard rain a few puddles . Bearings were destroyed within 500 miles or, less than two weeks after rain storm ride, very disappointing . I cant see how they would fair in a motocross situation if thisi s how they last in a street bike with out any high performance situation just putting around town no wheelies ....
They look great and work excellent.
Bearings were easy to install and this includes only one side so make sure you get 2 of these kits for either side of the quad!!
Fast shipping and real quality bearings, especially for the price.
Great replacement, perfect fit, does what it's supposed to, would recommend.
This kit had everything I needed at a great price
Great kit i would say i wont use any thing else this product is worth it everytime.
good bearing for a good price.
bearings slid right in with ease didn't even have to use a torch to install had them for about a week can't really comment on the durability
Bought these for my son's race quad , out if the package they just didn't seem to move as smooth as other brands . After install done a few runs and the quad lost on average 3 mph due to them not being as smooth as advertised. Will be pulling them out after only one week of use and replacing with another brand .
Seem to be as good as the oem bearings.
Just replaced the bearings on my fourwheeler and these are so much better with better seals and the bearing is more sealed. Hope I get more than 800 miles unlike I did with the factory bearings!
A nice sealed bearing but no grease inside of the sealed area.
I will have to run the bearings a while before review.
But I love the MotoSport decals :)
One option would be to get OEM bearings/seals, we have most everything in stock except 91053-MAZ-003 which is available from Honda.
