We’ve taken the hassle of converting your late model belt driven H-D® to chain drive. Whether you’re interested in a different final drive ratio, added driveline strength or more clearance for a wider tire, these kits will make your life easier. Kits are available with durable, high wearing RK Pro O-Ring chains (best for street use) or RK’s brutally strong, non-o-ring DR (Drag Race) chain.

SPORTSTER Choose between 19-26 teeth on the transmission sprocket; on the rear 46-65 (aluminum), 46-49 & 51 (chrome steel) and 49 & 51 (zinc steel). Suggested ranges: (’91-’03) 21/23 front, 46-51 rear sizes fit best; 2004-up models require larger diameter sprockets [25/26 front, 52-55 rear] to clear the passenger peg mounts on the frame). Sizes outside of these ranges may require modifications for proper clearance.

Street O-Ring Kits – Front sprockets are steel, rear are made from your choice of lightweight, extremely tough 7075-T6 aircraft quality aluminum, or steel in black, silver or chrome finish.
Due to available sprocket sizes, not all applications are available with steel rear sprockets.
New! Optional chain finishes! We now offer our O-Ring Street Chains in standard metallic finish or with the link plates finished in black or gold for a true finishing touch. Please select the desired finish when ordering.

Drag Race Kits – Front sprockets are steel, rear are made from lightweight, extremely tough 7075-T6 aircraft quality aluminum. RK Drag Race chain included in standard metallic finish.

Simply identify your motorcycle type and year group, what style of chain you wish to run, and what sprockets you’ve chosen and we’ll supply you with everything you’ll need for the conversion. Contact us to recommend what final drive ratio will work best for you, or choose your own (note: extremely small or large sprockets may require swing arm or frame modifications for clearance). 120 link chains are supplied, which must be shortened to fit.
