Rippin' through the track or trails does not have to rip up your dirt bike brakes, thanks to the Fastway Sharkfin rear disc guard. To keep the debris from destroying your rear brake disc Fastway constructed the Sharkfin out of 6061 billet aluminum, which offers superior protection with minimal weight gain. An open design allows mass amounts of air to pass through the Fastway Sharkfin, keeping your rotor cool and performing better. Fastway anodized the Sharkfin rear disc guard in black to create a tough surface that will last. Note: Some models will include Fastway spacers or mounting tabs.
