Other Norton crankshafts

Typical lightweight flywheel offset Norton crankshaft after balancing. This image shows optional sludge traps plugs which are recommended for high-mileage machines. An in-line oil filter is recommended for all cranks when sludge trap plugs are installed.

Note size of counterweight and amount of steel around big-end journal. In combination with the large oil cavity in the flywheel this means both the total crankshaft weight, and the interial weight, are significantly less then a stock crank. Total weight is about 4.5 to 5 pounds (2.3kg) lighter then a stock crank depending on connecting rods and piston weight used. This crankshaft was balanced for 325gram pistons and R&R alloy connecting rods.
