Moose Offroad MR-1 Black Aluminum Chain Guide — Beta RR RS RX Xtrainer 2010-2025

Moose Offroad MR-1 — 6061-T6 Aluminum Strength, Impact-Resistant TPU, and Mud-Shedding 3D Design

Protect your drivetrain and prevent costly DNFs with the Moose Offroad MR-1 Colored AL Chain Guide. Engineered specifically for the Beta motorcycle range, this guide is a significant upgrade over the stock plastic unit. In the technical and rocky terrain where Beta machines excel, a solid impact can easily bend a standard guide, leading to chain derailment or sprocket damage. The MR-1 guide provides a rigid 6061-T6 aluminum skeleton to maintain perfect chain alignment even after heavy hits.

The interior of the guide features a replaceable chain block manufactured from high-density TPU (Thermoplastic Polyurethane). This material is chosen for its incredible abrasion resistance and ability to absorb impacts without transferring all the energy to your swingarm tabs. Furthermore, the specialized 3D design of the aluminum shell is shaped to prevent mud and trail debris from packing inside the guide, which is a leading cause of chain derailment in deep woods or technical off-road conditions. Finished in a high-quality black anodization, it offers a "Works" look that resists UV fading over time.

• 6061-T6 Aluminum Body: Provides the structural rigidity needed to prevent bending and ensure consistent chain tracking.
• High-Density TPU Block: Guaranteed high wear resistance and impact absorption for extended drivetrain life.
• 3D Mud-Shedding Design: Specifically shaped to evacuate mud and debris, reducing the risk of chain derailment.
• UV-Resistant Anodizing: High-quality black finish that won't fade or discolor when exposed to sun and chemicals.
• Complete Kit: Includes all necessary mounting hardware for a direct, hassle-free installation on your Beta.

Moto-House MX Pro Tip:

Your chain guide is a wear item that often goes overlooked until it's too late. When installing the Moose Offroad MR-1 guide, check your chain tension and sprocket wear—a loose chain or a hooked sprocket will accelerate wear on the TPU block. We recommend periodically inspecting the internal slider; if you see the chain starting to wear into the aluminum shell, it’s time to replace the TPU insert. When mounting, use the provided hardware and a small amount of medium-strength thread locker on the bolts to ensure they stay secure through high-frequency vibrations.
