DSC BIKE SHOP has your 1/4" off set sprocket for a 240 tire kit. You need this sprocket to off set the chain to keep your extended chain in line to the rear sprocket attached to the new 240 wheel on your motorcycle. Our 530 ffront sprockets (AKA) countershaft sprockets, are made of heat treated and case hardened chromoly steel. Off-set sprockets are available in either 16 or 17 teeth.
You can choose from a front 530 16 tooth sprocket and a 530 17 tooth sprocket. And choose the off set in a 7mm=1/4, 10mm=3/8, or 13mm=1/2
