A large number of late-model Harley owners who prefer tall handlebars convinced us to develop the Thunder risers. This riser’s one-piece design increases riser stiffness and clamping power on rubber-mounted top trees, and is a boon to performance and style on practically any motorcycle. Investment-cast and CNC-machined stainless steel. 5/16” x 18 t.p.i. Stainless steel bar clamp hardware.

The black finish on Biltwell handlebars and risers is called Black Electrostatic Discharge or BED, and is applied the same way chrome plate is applied to raw materials. Like chrome plating, powdercoating and standard paint finishes, BED requires periodic care to maintain its luster. Soapy water and a soft cloth will remove surface dirt from BED, and common automotive waxes and polishes work great to protect the finish.

• Investment-cast stainless steel construction
• Fit bars with 1" diameter in clamping area
• 43/8​​" wide with 2" rise
• 31/2​​" on-center mounting holes accept 1/2​​" x 13 mounting hardware
• Include stainless top clamp hardware

Fitment: 

This one-piece riser fits rigid- and rubber-mounted top trees with 3.5” (89mm) center-to-center mounting holes only (Wide Glide, Narrow Glide, H-D aftermarket trees, etc.) If your top tree has different mounting holes, Thunder risers will not fit your motorcycle. Also, the holes on your trees must accept 1/2” O.D. hardware. The lower clamp is threaded to accept 1/2-13 mounting hardware (not included).
