Moose Offroad 28-1219 Swingarm Bearing Rebuild Kit — Beta EVO Trials 2009-2024

Moose Offroad — Premium Steel Rebuild Components, OEM-Quality Fit, and Restored Chassis Rigidity

Eliminate rear-end "slop" and restore the precise handling your trials machine demands with the Moose Offroad 28-1219 Swingarm Bearing Kit. Specifically engineered for the Beta EVO range, this kit provides a comprehensive solution for refreshing the most critical pivot point on your chassis. In the world of trials, where balance and technical precision are everything, even a tiny amount of play in the swingarm can negatively impact your suspension's performance and your ability to find traction.

This repair kit is constructed from high-grade steel components designed to meet or exceed OEM specifications while offering a much more affordable path to a total rebuild. It includes every bearing, seal, shaft, and spacer required to overhaul the swingarm pivot. By replacing your worn, rusted, or dry factory bearings with this kit, you’ll ensure a friction-free range of motion, allowing your rear shock to respond instantly to the terrain.

• Complete Pivot Overhaul: Includes all necessary bearings, seals, shafts, and spacers for a full swingarm rebuild.

• Restore Technical Precision: Eliminates lateral play in the swingarm to improve balance and suspension compliance.
• Comprehensive Fitment: Tailored for the Beta EVO lineup, including 125, 200, 250, 290, and 300 models (2-stroke and 4-stroke).
• Cost-Effective Solution: Offers factory-level performance and fitment at a fraction of the price of individual OEM parts.

Moto-House MX Pro Tip:

Trials bikes are frequently subjected to slow-speed water crossings and high-pressure cleaning, which can easily push moisture past swingarm seals. When installing the Moose Offroad 28-1219 kit, we recommend using a high-quality waterproof grease and packing the needle bearings thoroughly. To ensure a long service life, avoid aiming pressure washers directly at the pivot points. A properly maintained swingarm pivot not only improves the feel of your Beta EVO but also prevents the pivot bolt from seizing in the engine cases—a common and expensive issue to fix.
