Key Features
- 6061 Billet Aluminium Construction — Machined from premium 6061 billet aluminium, this rim offers exceptional strength-to-weight ratio and superior durability compared to standard plastic wheels, meaning it will withstand the rigours of serious RC racing and bashing without cracking or warping.
- Anodised Finish — The professional anodising process creates a hard, corrosion-resistant surface that protects the aluminium from oxidation, salt spray, moisture and general wear, ensuring your rims maintain their appearance and integrity through countless sessions at the track or bash spot.
- CNC Machined Precision — Every rim is precisely CNC machined to exacting tolerances, ensuring perfect balance, consistent fit and optimal performance with your Promoto-MX's drivetrain components, eliminating run-out issues that can compromise handling and tyre wear.
- True-to-Scale Motocross-Inspired Appearance — The design authentically replicates the look of real motocross machine wheels, giving your 1/4 scale Promoto-MX a genuinely realistic appearance that stands out from standard RC models and appeals to scale model purists and serious enthusiasts.
- V2 Bead Mounting Sleeve Compatible — This rear rim is fully compatible with the V2 Bead mounting sleeve system used on modern Promoto-MX models, ensuring hassle-free installation without requiring any modifications or adapters.
- Replacement Pro-Spec Aluminium Wheel Rim — Designed as a drop-in replacement component, this rim fits directly into your existing Pro-Spec Aluminium Rear Wheel assembly, making upgrades or repairs straightforward and allowing you to maintain peak performance without complete wheel replacement.
Technical Performance
The Pro-Spec Aluminium Rear Rim represents the pinnacle of RC wheel engineering for 1/4 scale models. Manufactured from 6061 billet aluminium, this material choice is crucial — 6061 aluminium offers the optimal balance between lightweight construction and exceptional structural rigidity, a combination that professional RC engineers have relied upon for decades. The billet construction means the entire rim is machined from a solid aluminium block, eliminating weak points and stress concentrations that plague welded or cast alternatives. The anodising process doesn't merely provide cosmetic appeal; it fundamentally strengthens the aluminium surface through electrochemical hardening, creating a wear-resistant layer that protects against corrosion in all weather conditions, an essential consideration for UK RC enthusiasts who may encounter damp conditions or salty coastal environments. Every rim undergoes CNC machining to precision tolerances, ensuring that wheel run-out remains minimal — this is critical because even tiny variations in wheel geometry can cause vibration, uneven tyre wear, and handling inconsistencies at speed. The V2 Bead mounting sleeve compatibility ensures this rear rim integrates seamlessly into the modern Promoto-MX platform, delivering improved handling response and traction through reduced unsprung weight and increased rigidity compared to standard plastic wheels. This component is positioned as a replacement wheel rim that fits the Pro-Spec Aluminium Rear Wheel, meaning you're upgrading a complete wheel assembly with a component that's been tested and proven to deliver measurable performance improvements in competitive and recreational settings.

Frequently Asked Questions
- Is the Pro-Spec Aluminium Rear Rim compatible with my Losi Promoto-MX? — Yes, this rear rim is specifically engineered for the Losi Promoto-MX and features compatibility with the V2 Bead mounting sleeve system used on current Promoto-MX models. It functions as a replacement rim for the Pro-Spec Aluminium Rear Wheel assembly, meaning it will integrate directly into your existing setup without requiring modifications or additional adapters.
- What makes aluminium rims better than plastic wheels for RC cars? — Aluminium rims offer several performance advantages over plastic alternatives: they provide superior rigidity which improves handling precision, they maintain consistent geometry under load without flex or distortion, they offer better heat dissipation which prevents brake fade, and they're significantly more durable when subjected to impacts or lateral loads during aggressive driving. For serious RC enthusiasts in the UK who demand peak performance from their models, aluminium is the professional choice.
- How does the anodising process benefit the rim? — Anodising creates a hard, corrosion-resistant oxide layer on the aluminium surface that's considerably tougher than bare metal. This process is essential for RC components that may be exposed to moisture, humidity, salt spray (particularly important for UK coastal areas), and general environmental wear. The anodised finish also provides enhanced aesthetic appeal with a professional appearance that resists discolouration and oxidation over time.
- Is this a complete wheel or just the rim? — This is a replacement rim component that fits into the Pro-Spec Aluminium Rear Wheel assembly. It's the outer wheel part with the tyre-mounting bead, designed to be used as a replacement or upgrade component rather than a complete ready-to-install wheel package.
- What is the difference between this Pro-Spec rim and standard Promoto-MX wheels? — Pro-Spec rims are manufactured from premium 6061 billet aluminium with CNC precision machining and professional anodising, whereas standard wheels are typically plastic or lower-grade materials. The Pro-Spec construction offers superior durability, better handling performance due to reduced flex, improved aesthetic authenticity with true-to-scale motocross styling, and longer lifespan even under competitive racing conditions.
- Can I use this rim with different tyres? — This rear rim is designed with a V2 Bead mounting system that's compatible with Promoto-MX-specific tyres. Always ensure any tyres you choose are rated for 1/4 scale Promoto-MX models to guarantee proper fit, balance and performance characteristics.
- How do I install this rim on my Promoto-MX? — The rim is designed as a straightforward replacement component that fits into your existing Pro-Spec Aluminium Rear Wheel assembly. Installation simply involves removing your old rim and mounting this new one onto the V2 Bead mounting sleeve — no tools or special equipment are required for the swap, making it an easy upgrade for any RC enthusiast.
