ODI Fusion Alloy Throttle Tube – H70FVCB (Cable Type, V-Twin 84+)
Updated June 20, 2026
The ODI Fusion Alloy Throttle Tube (H70FVCB) is a precision-machined replacement throttle tube designed for cable-actuated Harley-Davidson V-Twin motorcycles from 1984 onward. Constructed from 6061 aluminum with a hard-anodized black finish and integrated Teflon-lined nylon sleeves, it delivers a noticeably smoother throttle pull and return compared to stock plastic tubes. This tube is a direct upgrade for riders seeking reduced friction, improved feel, and long-term durability.

Design and Construction
The Fusion throttle tube is CNC-machined from 6061-T6 aluminum, then hard-anodized black for corrosion and wear resistance. Inside, it uses a nylon snap-cam and Teflon-impregnated sleeves that reduce friction between the tube and handlebar, eliminating the stickiness common with stock plastic tubes. The outer diameter is 1.125 inches, designed to fit standard 1-inch O.D. handlebars. The cable cam is machined specifically for dual-cable throttle systems (pull and return cables) found on 1984+ Harley V-Twins.
Vehicle Fitment and Compatibility
This part (MPN H70FVCB) is intended for cable-actuated Harley-Davidson V-Twin models from 1984 onward, including Touring, Softail, Dyna, Sportster, and V-Rod families. Specific compatible models include 2018-2021 Sportster Iron 1200 XLNS, 2018-2019 Sportster Forty-Eight Special XLXS, 2018-2019 Softail Sport Glide FLSB, 2006-2007 V-Rod CVO/SE models, and 1982-1986 Wide Glide FXWG. It is not compatible with ride-by-wire (electronic throttle) systems. Always verify your handlebar diameter (1 inch) and cable configuration before ordering.
Performance and Feel
By replacing the stock plastic throttle tube with this alloy unit, riders experience a more linear and consistent throttle action. The Teflon sleeves reduce static and dynamic friction, which can make low-speed maneuvering and precise throttle modulation easier. The hard-anodized surface also resists galling and wear from cable ends, prolonging the life of both the tube and cables. Many users report a noticeable reduction in wrist fatigue on long rides.
Installation Notes
Installation is a straightforward direct replacement: remove the grip and any existing throttle tube, slide the Fusion tube onto the handlebar, attach the throttle cables to the cam, and reinstall the grip. No special tools or modifications are required. Ensure the cables are properly routed and adjusted for free movement. The tube is sold as a single unit; grips are not included. ODI recommends using their compatible grips for optimal fit, but aftermarket 1-inch grips will also work.
