Moose Offroad 150-08001S Solid Rear Brake Rotor — Beta RR RS X-Pro 2013-2025

Moose Offroad — High-Content Stainless Steel, Mud-Specific Solid Design, and Superior Friction Grip

Master the most abrasive trail conditions with the Moose Offroad 150-08001S Solid Rear Brake Rotor. Specifically engineered for the 2013-2025 Beta RR, RS, and X-Pro lineup, this solid-surface rotor is the ultimate solution for extreme mud and sand racing. Standard vented rotors are designed for cooling, but in sloppy conditions, those vents act like a cheese grater, trapping grit and rapidly wearing down your brake pads. The solid design of the 150-08001S eliminates these entry points for mud, providing a consistent braking surface that dramatically extends the life of your pads and the rotor itself.

Manufactured from premium high-content stainless steel, this rotor offers a higher coefficient of friction than typical OEM offerings, resulting in better modularity and stopping power. The one-piece fixed design bolts directly to the hub, ensuring maximum rigidity and a consistent lever feel. Whether you are navigating a technical enduro section or a high-speed dual-sport route, this 240mm rotor is built to withstand the thermal stress of heavy braking while maintaining its structural integrity and resisting warping.

• Solid Surface Design: Engineered specifically for mud and sandy conditions to prevent abrasive material from trapping between the pad and rotor.
• High-Content Stainless Steel: Provides superior friction and bite compared to standard factory rotors for improved stopping performance.
• Enhanced Durability: Solid construction offers more surface area for wear resistance, significantly extending brake pad life in harsh environments.
• Precision Fitment: A direct bolt-on replacement for the 2013-2025 Beta range, compatible with all OEM standard brake calipers.
• Off-Road & Street Rated: Versatile enough for aggressive technical off-road racing and high-mileage dual-sport use.

Moto-House MX Pro Tip:

In the world of GNCC and Hard Enduro, a solid rear rotor is a "secret weapon" for survival. If you've ever finished a muddy race with zero brake pads left, this is the fix. When installing the Moose 150-08001S, we highly recommend installing a fresh set of sintered metal brake pads to get the most out of the high-friction stainless steel. Always use new rotor bolts and apply a medium-strength thread locker to ensure they stay secure through the intense vibrations of off-road riding. This 240mm rotor is the perfect match for the new 2025 Beta X-Pro and Race Edition models.

FAQ Questions

Q) Does this rotor fit the 2025 Beta 300 RR X-Pro?
A) Yes, this rotor is verified for the latest 2025 Beta X-Pro models and Race Edition models.

Q) Will this rotor make my brakes run hotter?
A) Because it lacks venting, it can retain more heat during extremely aggressive, constant braking. However, in muddy conditions, the trade-off for significantly longer pad life makes it the preferred choice for most off-road racers.
