You’ll NEVER need to buy another throttle tube or set of handlebars again!
The Zero Resistance Throttle is a revolutionary new Patent Pending frictionless and responsive throttle tube for motocross, dirt bikes, and sport bikes. How does it work? Simply put, the ZR Throttle has two radial ball bearings on each end of the throttle tube, with one bearing inside the throttle housing and one on the end of the handlebars. This gives the throttle assembly ultra-smooth quick turn action for more snap and quick response, with the benefit of life long longevity.

The frictionless motocross and motorcycle ZR Throttle tube difference.
ZR Throttle tubes will give you that “freshy” new bike feeling – forever. Unlike traditional plastic throttle tubes, the weight of the rider either pushing or pulling on the throttle will create “friction”. Over time the throttle and handlebars deteriorate and need replacement. With ZR Throttle bearings, the friction is eliminated, making your no-stick throttle assembly ultra-smooth and tough. The ZR Throttle is virtually a maintenance free throttle tube – and it’s made in the USA.

ZR Throttle’s Pro MX quality and durability.
The ZR Throttle is tough – tough as nails! This racing throttle tube has been tested by the best that the North East Off Road scene has to offer. These pro riders race with roost guards, leaving their throttle end exposed. The ZR Throttle is a reliable throttle that will not break if they crash.
