I'm asking about the All Balls kit because I don't want to buy the All Balls kit unless I know the bearings are made by a reputable manufacturer. All Balls does not make bearings, they just repackage and sell bearings made by someone else - same for Yamaha or any other vehicle manufacturer. SKF, KYK, NSK, Timken, and Koyo are a few of the reputable bearing manufacturers - there are lots of Chinese bearings being repackaged and sold as OEM replacements, and they tend to be crap. With the numbers/codes from a bearing or seal a bearing supply house can usually cross-reference one manufacturer to another.
If the All Balls kit uses good bearings, the price looks great, and I will order. However, the price is what makes me worry that they are using bearings from China... BTW - if there is no manufacturer name on the bearings, it is usually because the manufacturer would prefer to remain unknown.
Cheers,
Curtis
