Arlen Ness Polyurethane Riser Bushing Kit for 1973-Up Harley-Davidson
Handlebar flex and engine vibration translate directly to fatigue and imprecise feel, the Arlen Ness Polyurethane Riser Bushing Kit addresses both without visible modification. Proprietary polyurethane absorbs vibration at the riser tree while keeping handlebar inputs positive and direct, turning a vague stock feel into something noticeably more confident.
Key Features
- Proprietary polyurethane formulation absorbs engine vibration at the handlebar riser tree
- Eliminates handlebar flex without permanent modification to the frame or steering neck
- Heavy-duty cup washers resist bending and distortion unlike factory pressed-steel units
- Inner steel sleeves distribute clamp load correctly across the polyurethane bushings
- Two fitment groups with different tree hole sizes, verify your model before ordering
- Made in Taiwan
