Just like replacing with parts that come from japan,the chinese stuff scares me...
Im pretty sure the Pro X crank bearings are actually OEM. They are Koyo brand bearings and are the same as the ones that came out. Same bearing ss OEM for less than half the price.
crank bearing was the right and perfect fit for my 2002 yamaha yz250
The only issue I have with this is the pic makes it look like its a set not just a single bearing. I ordered it along with some other parts assuming it was a set. It is not. Its just one bearing. Yes I should have looked closer to see it says Bearing (singular) not Bearings. Aside from me paying closer attention they could also avoid this by not showing two bearings in the picture.
I've been using this bearing for many engine builds and haven't had any problems with them. They're the exact same ones Honda sells, for my '01 CR250, but not at the inflated Honda price.
used many bearings...I recomend these.
i have put these bearings in everything i work on, from a kx65 to a crf450 i'm very happy with the pro-x line of bearings and seal. you get a better than OEM item for a fraction of the cost.
these are a great deal because they are cheaper then most and just because they are cheaper doesnt mean they are worse. I have used my bike every weekend and more. Plus they were easy to install. Where could you go wrong? because im about 180 and it runs great. I have even had me and another on there so about 300 - 350 and it had no problem. so it isan awsome deal! i recommed u buy these.
The 1987 YZ250 had the O.D. - 62mm - I.D. - 30mm - Width - 16mm 23.6206C3 Crankshaft Bearing.
* Crankshaft requires 2 bearings (left & right)
