Top Performances SKF C3 crankshaft bearings (6204/6303) with Teflon handlebars. The bearings only fit the Top Performances 85 / 86ccm crankshaft (T9920410), which is used for Top Performances Maxikit 85 and 86ccm. NOTE: If you buy this set for Yamaha FS1 50 2T, do not use the simmerings, only the bearings.
Note: The bearings are open on both sides and therefore can not be turned incorrectly on the crank.
