Frequently Asked Questions
- What Losi motorcycles is this sprocket compatible with? — This hub chain sprocket fits the Losi 1/4 Promoto-MX and Promoto-SM motorcycle RTR models, including the Promoto-MX FXR, Promoto-MX Club MX, Promoto-MX Pro Circuit models, and the Promoto-SM FXR Supermoto variants. If you own any of these quarter-scale Losi motorcycles, this is the correct replacement sprocket.
- Why would I need to replace my sprocket? — Sprockets experience natural wear over time as the chain continuously engages with the teeth during riding. If you notice reduced power delivery, noise from the drivetrain, or visible damage to the teeth, replacement is necessary. Regular riders and competitive racers should keep spare sprockets on hand for quick maintenance between sessions.
- Is this a genuine Losi part? — Yes, this is an original equipment manufacturer part produced by Losi specifically for their Promoto-MX and Promoto-SM motorcycles. Using genuine OEM parts ensures perfect compatibility and maintains your machine at factory performance standards.
- How do I install this sprocket? — Installation requires removing the rear wheel and chain, then replacing the old sprocket with this new one on the hub. Detailed installation instructions are typically found in your motorcycle's manual, or you can contact RC Model Shop for guidance. The straightforward design means most RC enthusiasts can handle this replacement themselves.
- What is the difference between this clear sprocket and other colour options? — The clear finish is purely aesthetic and allows visibility of the internal hub structure. Functionally, this sprocket performs identically to other colour variants, so your choice can be based on your preference for appearance and the transparency effect you want on your motorcycle.
- Can beginners replace their own sprocket? — Absolutely. Sprocket replacement is one of the most straightforward drivetrain maintenance tasks in RC motorcycling. If you're comfortable working with basic tools and following instructions, you can easily replace a worn sprocket yourself without specialist knowledge.
