Nitrided, forged 86mm stroke, 1.625" "S" big end journal for non-S 1275/1300 block with stronger keyway for timing gears fitted.

Forged EN40B steel nitrided cranks are considered the ultimate in specification, even over the "billet" type. This is mainly because the grain pattern of a forging follows the shape of the webs and bearings whereas the billet type is machined across the grain. We stock all the forged types.heat treated for maximum durability. All are machined to fit 1275/1300 non-S center main except C-AEG479 which is "S".

All cranks have been re drawn to benefit from latest technology by having the much larger crank webs designed to reduce whip and resistance at high revs giving smoother running and easier balancing, plus being mass centre balanced which all help to provide great counter balancing features.

this is good as cranks can get.The bored holes for the big ends reduces weight of the crank and does not require drilling through the largecounterr balance C shape webs
