Wossner - HC piston Complete Piston (92mm) with 20mm gudgeon pin
Piston is 0.4mm higher, still flat, adds only a littleto the compression but has a far larger impact because it creates a proper squish. Only 0.4mm more piston but think BIGGER!!!
Suitable for the 400cc model 1996-2003 and available in size A B or C.
**Danger. You must fit a 20mm little end bush. GO TO 100123 for the bush. The advert warns against this item for the 400 because that is not the normal bush of course!
