RFX Pro F8 Tapered Handlebars

Competition-level strength, controlled flex, and a reinforced crossbar design for motocross and off-road riders who prefer a firmer handlebar feel.

The RFX Pro F8 Handlebars combine lightweight 7075-T6 aluminum construction with an oversized tapered profile and incorporated cross-brace. The result is a strong, responsive motocross handlebar designed to provide accurate front-end feedback while helping manage vibration and harsh impacts.

Compared with the crossbar-free RFX F7, the F8 offers a slightly firmer and more connected feel. It is an excellent choice for racers and aggressive off-road riders who want controlled flex without sacrificing the familiar support of a traditional crossbar design.

Competition-Level Strength

Heat-treated 7075-T6 aluminum, extended oversized sections, and a reinforced crossbrace help support demanding motocross use.

Controlled Rider Feedback

Engineered wall thickness provides carefully controlled flex while maintaining a precise and connected front-end feel.

Reduced Vibration

Progressive Damping Control is designed to help manage vibration through the grip area and reduce rider fatigue.

Choosing the Correct Handlebar Bend

Motorcycle names and competing handlebar numbers are provided as comparison references rather than guaranteed vehicle-specific fitment. Compare the width, height, rise, clamp area, and sweep with your current handlebar before ordering. Confirm that the motorcycle has compatible 28.6 mm / 1-1/8-inch oversized bar mounts. Motorcycles equipped with standard 22.2 mm / 7/8-inch mounts require compatible oversized mounts or adapters.

Installation Note

Confirm adequate clearance for the throttle, cables, brake hose, controls, number plate, and fuel tank through the full steering range. Tighten the handlebar mounts and controls according to the motorcycle manufacturer's recommended torque specifications.
