If you are performing a complete engine rebuild and your drive side roller bearing is in need of replacement I highly suggest installing a BSA and Triumph roller bearing manufactured by a reputable company such as the bearings we have to offer you today.
Roller bearings fitted to Triumph 650 and 750 unit twins as well as BSA 500 and 650 unit twins came equipped with a MRJA 1 1/8 roller bearing. Original bearings where made by RHP, R&M and Hoffmann. Finding those original roller bearings are almost impossible to find today. Luckily the MRJA 1 1/8 roller bearings we offering today are just as good, affordable and available.
We are aware that there are many sources online and the popular forums that are talking about the roller bearing clearance rating on each bearing that they should have. I will address this below so you can select the proper roller bearing for your application and also have confidence while doing so.
