Wow. New cranks for all Ossa motors. Not sure why, but my motors run quieter with these, compared to rebuilt cranks with the rod conversion. Excellent.

New cranks makes rebuilds faster.

Correct size crank for a faster rebuild. No more machining for the HD rod kit.

Perfect fit

This crank dropped right into my 1971 Stiletto TT engine cases perfectly and finished the balance of the 2019 AHRMA race season (totaling 7 nationals) with no issues.

Amazing Turn around

While I have not gotten into the project I will say that yje Crank arrived faster than the engine stand needed and bought from another source. Thew 4th of July discount program was great as well. I have bought from Vintco beforee and it only gets better. THANKS SO MUCH. I currently have 10 different Ossa's from a 1967 Pioneer 230 to the newest which is this 1973 SDR Pioneers and a couple of Stilettos. 1973 About ended my Ossa time in my youth so I have focused on things I have owned and enjoyed. my 4 Stroke world is filled with HD's and Tube frame Buells

Nice quality replacement crankshaft. Nice fitment. Would be great if you offered crankshaft shims to aid in setting endplay. Thanks!
