All Triumph crankshafts are welded, ground, nitrided and balanced to your requirements. Customer must supply donor crank (flywheel not required) and weight of one piston, rings, wrist pin, circlips, connecting rod. Bearing shells are supplied. Standard Triumph offsets include 90 degree & 76 degree. Other offsets available upon request. All Triumph crankshafts include lightweight welded flywheel that makes an offset crank 650 beat a stock 750 with ease! Drive side journal is offset behind the timing side journal in the direction of crank rotation to assist users in finding custom camshafts. Triumph cams cannot be modified so a special cam from a motorcycle cam vendor is recommended. Cam modification diagrams are available at no additional charge. An oil filter must be used with all offset crankshafts as sludge trap is removed. All cranks balanced to 50% unless other balance factor specified by customer.
