TC Bros. 1" Motorcycle Throttle

Looking to eliminate the bulky throttle and switch housings on your Harley-Davidson-based custom motorcycle? Try a TC Bros. throttle.

Minimalist design
Investment-cast housing
CNC-machined billet tube
Accepts many aftermarket integrated grip tubes
Available in two finishes and single- or dual- cable configuration
Chrome-plated cable ferrule kit included to accept nearly any factory Harley-style pull-type throttle cable
Ferrule kit is also available separately
Tube accepts barrel-type cable ends; replacement ends for round cable ends are available separately

This minimalist throttle features an investment-cast aluminum housing with classic styling. The billet aluminum grip tube is CNC-machined and knurled to accept a huge variety of aftermarket rubber grips and resist the dreaded "slippy grip."

Got a set of one-piece grips (with a built-in throttle tube) that you love? No problem. The housing accommodates most stock or aftermarket Harley one-piece style grip tubes—just swap out the included throttle tube.

Each throttle includes an assortment of chrome-plated ferrules that accept threaded and snap-lock style housing ends, making fitment of nearly any Harley-Davidson factory-type pull-style cable possible, regardless of carburetor configuration. The included tube is set up for later barrel-style cable ends—if you're using an earlier carburetor and cable or you've lost your factory ends, replacement ends are available separately.

These throttles are available in single-or dual-cable configurations in either a black anodized or hand polished finish. Select a dual-cable throttle if you're planning on retaining a factory-type double cable layout; builders designing a custom controls arrangement generally choose a single cable setup.
