Hi all, I have a Daytona 955i centennial edition (2002) and the crank has sheared off at the starter clutch end flush with the casing. I can't find a replacement crank (so far anyway) and was wondering if it might just be easier to get a donor engine. My bike has forged crank, con rods, pistons and liners to create and cope with 147hp compared to earlier 955i engines ranging from 108 to 128hp so I need a 2002 or newer engine. Could I fit a Daytona 06 engine into the frame? Would it be compatible with everything else? I dont fancy putting a Sprint or Speed Triple engine in because of the power loss. If I have to swap out the crank could i use any crank from a 955i 2002 or later as I think the power increase was due to the piston size and compression ratio? Any help/advice/tips etc are greatly appreciated.

Welcome. The increase in power did not come from an increase in piston bore. All 955 Daytonas have the same bore and stroke. The 1050 engine also has the same bore, longer stroke.
