Bullet Proof Designs' name says it all when it comes to protection. They have been making guards and braces for many years that have been tried and trued by countless professional racers for numerous platforms in the worlds toughest conditions. This rear disc guard is comprised of solid 6061 Billet Aluminum for extreme strength. The surface that protects the disc is also much thicker than the previous models made for dirt bikes, which comes in at around 1/2" thick! A big complement to this disc guard is that they have incorporated a brake caliper guard which comes included and secures to carrier, so no extra bracketry to keep the installation simple. Not only will you now have a billet brake caliper carrier, you have protection for both the caliper and brake rotor which is key for any off-road excursion, especially those in remote areas where brakes are very important. Backed by Bullet Proof Designs' lifetime warranty, you will not need to worry about a thing when it comes to this guard. Simply grip the throttle and twist it!
