Belt Drives Ltd 11mm Belt Drive Kit for 1948-1954 Harley-Davidson FL 47-31TK-1

If you're running a classic Harley-Davidson FL from the pre-1955 era, a belt drive conversion eliminates the maintenance headaches of chain lubrication while delivering smoother power delivery to the rear wheel. Belt Drives Ltd's 11mm kit replaces messy, noisy chain systems with precision-engineered components that reduce friction and vibration—critical upgrades for riders who demand reliability on long rides. This is a bolt-on solution that modernizes your vintage machine without compromising its authentic character.

The hard anodized aluminum pulley and clutch basket resist corrosion and wear, essential for machines that see regular use. The lightweight construction keeps your motorcycle's rotating mass minimal, preserving the handling characteristics purists expect from mid-century Harleys. Front pulley threads allow quick removal when maintenance is needed, saving you time in the garage.
