The Thruster Grips from Biltwell are made of Krayton rubber and feature a diamond pattern reminiscent of a custom upholstered seat. 
The larger flange hints at vintage motocross styling.
Subtle Biltwell branding on the end cap completes the look.

These grips are sold per pair and are available in 1" (the size needed for all Harley-Davidsons and other 'cruiser' style motorcycles) & 7/8" (common on many vintage British, European and Japanese motorcycles such as Triumph, Honda and Yamaha).

SPECS

Motorcycle grips have two different inside diameters. The grip for the left side of the handlebar has a smaller diameter, and the right side grip has a larger inside diameter to fit over your throttle tube. Grips are manufactured to have a tight fit, you don't want one sliding off while taking a corner or twisting the throttle!
We recommend using WD-40 to help get them into place and suggest letting them dry overnight.

Alternatively, you can use compressed air as seen in the Basic Motorcycle Grip Info & Install video ;

Note: Using Biltwell rubber grips on H-Ds will often require that your motorcycle is equipped with an aftermarket throttle tube (the Biltwell Whiskey throttle tube, for instance). The grips do not have a built in plastic throttle tube, they are meant to slide over a higher-quality aluminum tube.

Please note there is a lead time of approximately 2-3 weeks if we do not have the style in stock.
