Dave's Favorite Bearing: The Main Bearing on the Drive Side on Vintage BSA and Triumph Twins 

CN, C2 and C3 bearings are all under the same part number (70-2879 for Triumph and 68-0625 for the BSA CN bearing). Dave talks us through the different bearings, their history and how to distinguish them. (With special appearances from our old friends Stacy and Jürgen!) Check it out for some vintage Brit bike info.
