Hi,

Koyo bearing numbers.

left bearing 83B569 DASH2-9TCS39
middle bearing should be the same as left
right bearing 83B569 AASH2-9TCS39 (snap ring bearing)

You can get the right crankshaft seal from T2 racing and the centre bearing seal also. The left seal is still available from Honda. (91201-km4-003
