The Motorcycle Rear Disc Guard by Luckyway Metal is a high-performance protective accessory designed to shield the rear brake disc of motorcycles from rocks, debris, and impacts, ensuring reliable braking performance and extended disc lifespan in off-road and street conditions. Crafted by a leading China-based manufacturer with over a decade of CNC-machining expertise, it’s made from 6061 T6 aluminum or high-density polyethylene (HDPE), mounts to the brake carrier or frame with M6/M8 bolts, and fits models from KTM, Husqvarna, GasGas, Honda, Yamaha, Kawasaki, Suzuki, Beta, and Sherco (e.g., KTM 450 SX-F, Husqvarna FC 450, Yamaha YZ250F, Honda CRF450R) for 2020-2025 models. Ideal for motocross racers, trail riders, and street enthusiasts, it builds on your interest in protective components like radiator guards, linkage guards, and handlebars (April 17-21, 2025), reflecting Luckyway’s reputation for lightweight, precision-crafted parts with global shipping (March 23, April 14, 2025). Whether you’re navigating rocky trails or riding urban roads, this rear disc guard offers robust protection, easy installation, and enhanced braking reliability.
What Is a Motorcycle Rear Disc Guard?
A Motorcycle Rear Disc Guard is a protective shield that covers the rear brake disc, preventing damage from debris, rocks, or crashes that could bend or gouge the rotor, compromising braking performance. Made from CNC-machined aluminum or durable plastics like HDPE, it mounts to the brake carrier, caliper bracket, or frame, often replacing the stock carrier for added strength, as seen in Bullet Proof Designs’ guards for KTM and Enduro Engineering’s kits (Web ID: 7, 4). This guard ensures braking efficiency, aligning with your focus on protective components like radiator guards and linkage guards (April 21, 2025). Unlike front disc guards, which prioritize visibility, rear disc guards focus on shielding the low, exposed rotor, critical for off-road durability, per NiceCNC’s insights (Web ID: 24).
Why Use a Motorcycle Rear Disc Guard?
Rear disc guards prevent costly rotor damage, which can reduce braking power or require replacements costing $100-$300, particularly in off-road conditions where rocks and logs are common, per Bullet Proof Designs (Web ID: 7). They protect the disc without blocking it, unlike bent aluminum guards, and maintain braking performance, per AXP Racing’s HDPE designs (Web ID: 5). Luckyway’s guards, made from aluminum or HDPE, offer 800-1,200 hours of corrosion resistance and withstand impacts, ideal for models like Kawasaki KX450 or Husqvarna TE 300, complementing your interest in durable parts like exhaust end caps and foot pegs (April 21, 2025). Their sleek designs also enhance bike aesthetics, appealing to custom builders, per Rocky Mountain ATV/MC reviews (Web ID: 5).
