Kuryakyn Kinetic Throttle Boss Chrome - 6354

The Kuryakyn Kinetic Throttle Boss Chrome (Part #6354) is a small, adjustable palm-support paddle designed specifically for use with Kuryakyn Kinetic Grips on Harley-Davidson motorcycles. If long-distance highway riding leaves your throttle hand fatigued, this chrome throttle boss positions itself under your palm to help you slightly relax your grip and maintain a constant speed — making it a simple, affordable upgrade that can genuinely change the feel of a long ride.

Key Features & Benefits

• Palm pressure relief: The adjustable paddle positions under the palm of your throttle hand, allowing you to ease your grip without losing control of the throttle — a real benefit on extended highway stretches where hand fatigue sets in.
• Adjustable design: The paddle is adjustable, so you can dial in the exact position that works best for your hand size and riding style, rather than being locked into a one-size-fits-all setup.
• Chrome finish with black inlay: The chrome finish coordinates with Kuryakyn's Kinetic accessories line, keeping your handlebars looking cohesive and polished.
• Coordinates with the full Kinetic line: Designed to pair with Kuryakyn Kinetic Grips and the broader Kinetic accessories family, so it integrates seamlessly with existing Kuryakyn hardware.
• Sold individually: Lets you purchase exactly what you need — one throttle-side boss — without paying for parts you don't want.

Fitment

The Kuryakyn 6354 Kinetic Throttle Boss is designed for use with Kuryakyn Kinetic Grips on Harley-Davidson motorcycles. It is built to coordinate with the entire Kuryakyn Kinetic accessories line. Because this throttle boss mounts to the Kinetic Grip itself rather than directly to the handlebar, compatibility depends on having the correct Kuryakyn Kinetic Grips installed. If you are unsure whether this part is compatible with your specific bike and grip setup, use the fitment help contact below before ordering.

Not confirmed for use with non-Kinetic grip styles or non-Harley-Davidson applications based on available product information.
