MCS Sprockets Motor

15 products — part of all Sprockets Motor

MCS engine output sprockets give Harley-Davidson owners direct-fit replacements for the motor sprocket that transfers drive from the gearbox output shaft to the rear belt or chain. The motor sprocket is a wear item that requires periodic inspection and replacement — worn teeth cause the belt or chain to ride unevenly, accelerating wear on the drive component and potentially causing premature failure mid-ride. MCS produce motor sprockets to the tooth count and spline specifications of the main Harley-Davidson transmission families, with options for both belt-drive and chain-drive final drive configurations depending on the model. Correct tooth count selection is important as changing sprocket size alters the overall drive ratio and affects road speed relative to engine RPM. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks MCS motor sprockets alongside a full drivetrain and belt drive accessory range.
