• Axle-Based Mounting: Both guards attach directly to the axle — the strongest point on the wheel — so impacts transfer to solid metal, not weak brackets or caliper bolts.
• Triple-Lock Front Guard: The front guard uses three engagement points: two M6 fasteners plus axle mounting, so it stays secure even after hard rock strikes.
• Full Coverage Where It Counts: Front guard covers the leading edge, front face, and bottom of the rotor — the exact areas that take hits from rocks and debris.
• Replaces Weak OEM Hanger: The rear guard completely replaces the stock brake hanger with a purpose-built unit that protects the rotor and functions as a proper brake hanger at the same time.
• Bearing Seal Protected: The front hub mount is designed to keep the wheel bearing seal intact, preventing a failure that would be far more costly than a bent rotor.
• Low Unsprung Weight: Front guard weighs 13 oz and rear guard weighs 6 oz — minimal added weight so suspension action stays sharp in technical terrain.
• Quick Install: Designed to go on easily with included Loctite and first class manual
• Front Hub Mount Thickness: 8.5 mm
• Front Guard Weight: 13 oz
• Rear Guard Weight: 6 oz
• Total Weight: 1.7 lbs
• Front Fasteners: Two M6 fasteners plus axle mount
• Front Axle Compatibility: 22 mm
• Rear Axle Compatibility: 20 mm, 22 mm, or 25 mm
• Caliper Compatibility: OEM and Braketec
• Manufacturing Method: CNC machined
• Dimensions: 3.5 × 7 × 10.25 in
Bent rotors end rides. These guards are built to stop that from happening on KTM, Husqvarna, and GASGAS dirt bikes.
AltRider has direct roots in dirt riding. That experience shaped both guards. The front guard mounts to the 22mm axle using a thick hub mount — not to caliper bolts or aluminum axle screws, which are not built to absorb impacts. Coverage focuses on the leading edge, front face, and bottom of the rotor, where rocks actually strike. The hub mount design also keeps the wheel bearing seal intact.
The rear guard replaces the stock brake hanger entirely. The OEM hanger was not designed for trail impacts. This one is. It anchors directly to the rear axle and fits OEM and Braketec calipers precisely.
Both guards are CNC machined. Combined weight is 1.7 lbs. A single replacement rotor costs more than this set.

Install Rear Rotor Guard Instructions:
• Rock-Ready Coverage: Guard covers the leading edge, front, and bottom of the rotor — the exact zones that take direct hits from rocks and debris.
• Three-Point Mount: Two M6 fasteners plus axle mounting create three solid engagement points, so the guard stays in place under hard impacts instead of flexing or shifting.
• Thick Hub Mount: The 8.5 mm hub mount connects only to strong structural points on the axle — not to weak aluminum axle screws or caliper bolts that can fail on impact.
• Bearing Protection: The hub mount design keeps the wheel bearing seal intact, preventing dirt and water intrusion that would destroy the bearing after a hit.
• Low Unsprung Weight: At only 13 oz, the guard adds minimal unsprung weight, so handling and suspension performance stay sharp in technical terrain.
• Quick Install: Designed to go on easily with included Loctite and first class manual
• Material: CNC-machined aluminum
• Hub Mount Thickness: 8.5 mm
• Axle Size: 22 mm
• Fasteners: 2× M6 plus axle mount (triple-point system)
• Weight: 13 oz (0.36 kg) / 0.85 lbs
• Dimensions: 1.5 × 10 × 7 in
A bent rotor ends your ride. On rocky terrain, it's not a question of if your front disc takes a hit — it's when. This guard is built around that reality.
AltRider comes from dirt riding. The design here reflects that. Coverage is focused where rocks actually strike: the leading edge, the front face, and the bottom of the rotor. The hub mount connects only to strong structural points — not to aluminum axle screws or caliper bolts that can deform under impact.
Trail-side rotor straightening doesn't work. This guard does.

Install Front Rotor Guard Instructions:
• Replaces Weak OEM Part: The stock brake hanger was never designed to take impacts — this guard completely replaces it with a purpose-built CNC aluminum unit.
• Axle-Mounted Strength: Mounts directly to your rear axle (20mm, 22mm, or 25mm) so impact force goes into the strongest part of your bike, not a flimsy bracket.
• Rotor Protection: Shields your rear disc from rocks and trail debris — a single hard hit to an unprotected rotor can bend it and end your ride.
• Precise Caliper Fit: CNC machined for exact clearance with OEM and Braketec calipers — no rubbing, no shimming, no modifications needed.
• Lightweight Design: At just 6oz, it adds real protection without increasing unsprung weight that would hurt your suspension performance.
• Quick Install: Designed to go on easily with included Loctite and first class manual
• Material: CNC-machined aluminum
• Weight: 6 oz (0.17 kg)
• Compatible Axle Sizes: 20mm, 22mm, 25mm
• Package Weight: 0.85 lbs
• Package Dimensions: 2 × 5.25 × 10.25 in
One rock hit to an unprotected rear disc can bend it and end your ride. AltRider built this guard after seeing too many bent rotors and destroyed brake hangers on the trail. The stock KTM, Husqvarna, and GASGAS brake hanger was never designed to absorb impacts. This one is.
The rear guard replaces the OEM brake hanger entirely. It anchors directly to your rear axle, so impact force transfers into the strongest part of the bike. That direct connection is what makes it work. No weak brackets. No flimsy mounts.
CNC precision means the fit is exact with your caliper setup. No rubbing, no shimming, no modifications. At 6oz, it adds real protection without the unsprung weight penalty that hurts suspension performance in rough terrain.
