Part 56-2945.CRANK1 is the earlier 17-tooth crankshaft, designed for engines using the 25H-type cam chain.

This part cross-references to Yamaha OEM number:

5VL-W1140-00-KD

Please note that there is no fully reliable year-only fitment for these crankshafts, as Yamaha used both earlier and later engine configurations across overlapping years in some markets.

The safest way to identify the correct crankshaft is by checking the cam chain type and crankshaft sprocket tooth count, rather than relying only on the registration year.
