This is genuine performance engineering applied to RC components, and it shows in every detail.
Key Features
- 6061 Billet Aluminium Construction — The rim is machined from aerospace-grade 6061 billet aluminium, which provides exceptional durability and impact resistance whilst maintaining a lightweight profile that doesn't compromise your Promoto-SM's performance characteristics or handling balance.
- Anodised Finish — The professional anodising process creates a protective oxide layer that resists corrosion, weathering, and the wear from repeated use, ensuring the rim maintains its structural integrity and appearance through extended use in all UK weather conditions.
- CNC Machined Precision — Every rim is precision-machined using CNC technology, ensuring consistent quality, perfect fitment, and reliable compatibility with your Promoto-SM platform without requiring modification or adjustment.
- True-to-Scale Supermoto-Inspired Appearance — The design authentically replicates genuine supermoto wheel styling, delivering impressive visual realism that enhances the overall aesthetic of your 1/4 scale RC motorcycle and satisfies the demands of scale-conscious builders.
- Compatible with V2 Bead SM Mounting Sleeve — The rim works seamlessly with the V2 Bead SM mounting sleeve system, ensuring reliable fitment and eliminating compatibility concerns when installing or replacing your front wheel assembly.
- Replacement Pro-Spec Aluminum SM Wheel Rim — This component is specifically engineered as a replacement option for existing Promoto-SM setups, making it simple to upgrade your current wheels or repair damaged rims without requiring additional modifications to your RC motorcycle.
- Designed for Extreme Environments — The Pro-Spec range is engineered to perform in demanding conditions and take a beating, making it the ideal choice for aggressive riding, jumping, bashing, and competitive use where standard components might fail.
- 3D Printable Lacing Fixture Tool Available — Pro-Line provides access to downloadable STL files for a 3D-printed lacing fixture tool, enabling enthusiasts to perform spoke replacements themselves and maintain their wheels without relying on external service providers.
Technical Performance
This Pro-Spec front rim represents the application of serious engineering principles to RC component design. The 6061 billet aluminium material is selected specifically for its ability to withstand repeated impacts whilst resisting permanent deformation, a critical characteristic for any component that will experience regular contact with track surfaces, jumps, and obstacles. The CNC machining process ensures that every rim meets identical tolerances and specifications, eliminating the variability that can plague cast or stamped alternatives. The anodised finish serves multiple purposes: it provides aesthetic enhancement with a professional appearance, creates a protective barrier against corrosion and oxidation, and improves the rim's resistance to weathering and UV degradation. For RC enthusiasts in the UK who use their machines in varied weather conditions, this corrosion protection is genuinely valuable. The V2 Bead SM mounting sleeve compatibility ensures that installation is straightforward and that the rim seats properly on your Promoto-SM platform, maintaining consistent geometry and handling characteristics. The weight distribution and structural properties of this rim have been engineered to complement the dynamics of the Promoto-SM motorcycle, ensuring that performance isn't compromised by component upgrades. Whether you're running aggressive track sessions, bashing in the garden, or competing in organised events, this rim provides the durability and consistency that serious RC enthusiasts expect from Pro-Line components.

Frequently Asked Questions
- Is the Pro-Line Pro-Spec Black Aluminium Front Rim compatible with my Losi Promoto-SM? — Yes, this rim is specifically engineered for the Losi Promoto-SM platform and works with the V2 Bead SM mounting sleeve system. The Promoto-SM FXR Supermoto models (both standard RTR and versions with battery and charger included) are fully compatible with this component. If you're uncertain about your specific Promoto-SM variant, contact our RC specialists at RC Model Shop for confirmation.
- What makes the 6061 billet aluminium construction special compared to other wheel rims? — 6061 billet aluminium is aerospace-grade material selected for its exceptional strength-to-weight ratio and impact resistance. Unlike cast wheels that can crack or stamped steel wheels that can dent and bend, this billet construction resists permanent deformation whilst remaining lightweight. The material also responds well to CNC machining, allowing for the precise tolerances required for consistent performance.
- Can I repair the spokes on this rim myself? — Yes. Pro-Line provides downloadable STL files for a 3D-printed lacing fixture tool that enables you to replace spokes without external service providers. This is an excellent feature for enthusiasts who prefer to maintain their own equipment and want to extend the lifespan of their wheels through self-service spoke replacement.
- How does the anodised finish protect my rim? — The anodising process creates a protective oxide layer on the aluminium surface that prevents corrosion, resists weathering, and protects against UV degradation. For RC enthusiasts in the UK using their machines in variable weather conditions, this corrosion protection means your investment maintains its appearance and structural integrity through extended use and exposure to moisture.
- Is this suitable for competitive use, or is it just for casual bashing? — The Pro-Spec range is specifically engineered for extreme environments and demanding use, making it suitable for competitive events, aggressive bashing, jumping, and high-performance riding. Whether you're competing seriously or just enjoying weekend sessions, the durability and precision of this component make it an excellent investment.
- What is the difference between Pro-Spec rims and standard replacement wheels? — Pro-Spec components are built using premium materials (6061 billet aluminium rather than cast or stamped alternatives), precision CNC machining rather than standard production methods, and professional anodising for protection and aesthetics. The engineering focus is on durability in extreme conditions and long-term reliability, making them superior to budget alternatives.
- Will this rim fit other Losi models? — This rim is specifically designed for the Promoto-SM platform. If you own a different Losi model, please check compatibility or contact RC Model Shop to confirm fitment before purchasing.
