    A very good quality bearing, but for Simson cases should use one with a clearance of c3. I recommend.

    I own a 2006 Kawasaki KX 85. The newly ordered bearings give the impression of being solid and sturdy, they do not have the slightest play and also their dimensions are in line with their expected parameters. The installation went without any problem after freezing them in the freezer before installation without much force I was able to shove them into the wheel hub. Currently everything works properly and I do not see any possible defects, the wheel does not have any play. So in good conscience I can recommend this product to others. Regards :)

    This bearing does not fit the front wheel to the motorcycle even after the raceway is knocked out . It is better to use a garland .

    Great accuracy of fit. I would buy again and again. Fits my Bashan 250s-11b perfectly. Bearings run smoothly and are still in top condition. (Installed approx. 1 year ago)

    The product is well made with no defects, it has eliminated the backlash I had on the hub. The bearings rotate freely and are already lubricated. I recommend
