Key Features
- CNC Machined 6061 Billet Aluminum Construction — The hub is precision-engineered from premium 6061 billet aluminum, which is renowned in the RC industry for its exceptional strength-to-weight ratio and durability. This material choice means the hub can withstand extreme forces during high-speed runs and technical manoeuvres without cracking or failing, making it far superior to plastic alternatives often found on stock components.
- Anodised Finish for Superior Protection — The professional anodising process creates a protective oxide layer on the aluminum surface, significantly improving corrosion resistance and extending the lifespan of the component. This coating is particularly important for RC motorcycles that may encounter wet conditions or be exposed to the elements during outdoor riding sessions, ensuring your investment remains in pristine condition for years to come.
- True-to-Scale Motocross-Inspired Appearance — The design of this rear hub captures the authentic look of full-scale motocross machinery, giving your Promoto-MX a stunning visual upgrade that reflects the genuine engineering quality underneath. This attention to detail in appearance is important to RC enthusiasts who want their machines to look as impressive as they perform, and the blue anodised finish provides an eye-catching colour option that stands out on the track or at RC events.
- Perfect Compatibility with Pro-Spec Aluminum Rear Rim with Spokes — This hub is specifically engineered to work seamlessly with Pro-Spec Aluminum Rear Rim with Spokes, ensuring perfect fitment and optimal performance. When paired together, these components create a complete rear wheel assembly that delivers unmatched durability and performance characteristics, allowing you to build a fully upgraded drivetrain that works in perfect harmony.
- Replacement Component for Promoto-MX — Whether you're replacing a damaged hub, upgrading from stock components, or building a complete Pro-Spec aluminum setup, this hub is the ideal replacement part. As a genuine Losi component, it maintains the exact specifications and tolerances required for your Promoto-MX, ensuring no fitment issues or compatibility problems.
Technical Performance
The PRO 1/4 Pro-Spec Aluminum Rear Hub Blue represents a significant technical advancement over stock plastic hubs commonly found on entry-level RC motorcycles. Manufactured from 6061 billet aluminum through precision CNC machining, this component offers superior strength, rigidity, and heat dissipation compared to alternative materials. The anodising process adds a protective surface layer that resists corrosion and impacts, extending the component's service life even in demanding riding conditions. For riders in the UK who regularly take their Promoto-MX to outdoor locations, exposure to moisture, dirt, and variable weather conditions, this level of engineering becomes genuinely valuable. The hub's geometry and tolerances are designed specifically to work with the Promoto-MX drivetrain, ensuring perfect fitment and eliminating any play or slop that could affect handling or precision. When combined with Pro-Spec Aluminum Rear Rim with Spokes and quality tyres, this hub contributes to a dramatically improved ride experience with better acceleration response, improved handling through corners, and enhanced reliability during extended racing sessions. The 1/4 scale of the Promoto-MX platform means this hub handles substantial forces during operation, and the aluminum construction is specifically chosen to manage these demands without fatigue failure or deformation. RC enthusiasts building competition-grade setups or simply wanting the best-in-class components for their machine will find this hub delivers the engineering quality and performance characteristics they seek.

Frequently Asked Questions
- Is the Pro-Spec Aluminum Rear Hub compatible with all Promoto-MX models? — This hub is specifically designed for the Losi Promoto-MX and fits perfectly with the Pro-Spec Aluminum Rear Rim with Spokes. It is a genuine Losi component manufactured to exacting tolerances, so compatibility is guaranteed when used with genuine Promoto-MX platforms and matching Pro-Spec components. If you have a Promoto-MX and want to upgrade to Pro-Spec aluminum components, this hub is the correct choice for the rear wheel position.
- What are the advantages of upgrading to an aluminum hub over stock plastic components? — Aluminum hubs offer several significant advantages: they provide superior strength and rigidity, which translates to better handling precision and more responsive steering feedback; they dissipate heat more effectively during high-speed running; they resist impact damage far better than plastic; and they maintain their tolerances longer, reducing play and slop in the drivetrain. For riders who push their Promoto-MX hard, these advantages accumulate to create a noticeably better ride experience and longer component lifespan.
- Does the anodising finish affect performance or just appearance? — The anodising serves both aesthetic and functional purposes. Whilst the blue colour provides the stunning visual upgrade, the anodised coating also provides genuine functional benefits by creating a protective layer that resists corrosion, reduces friction, and protects the underlying aluminum from oxidation. This means the anodising is not just cosmetic—it actively extends the life and reliability of the component, particularly important for RC vehicles that may encounter wet conditions or be stored for periods between use.
- Can I use this hub with non-Pro-Spec wheels? — This hub is specifically engineered to work with the Pro-Spec Aluminum Rear Rim with Spokes to form a complete assembly. Whilst the hub itself is a universal fitment on the Promoto-MX rear axle, optimal performance and intended functionality is achieved when paired with the matching Pro-Spec rim. Using this hub with other wheel designs may result in fitment issues or suboptimal performance characteristics.
- What scale is the Promoto-MX and what does this mean? — The Promoto-MX is a 1/4 scale RC motorcycle, meaning it is one-quarter the size of a full-scale motocross motorcycle. This 1/4 scale represents the size category that Losi has chosen for this platform, providing a good balance between detail, handling characteristics, and power delivery. The hub's dimensions and specifications are optimised for this 1/4 scale format.
- How do I know this is a genuine Losi component? — This part carries the genuine model number G-PRO283702 and is supplied through authorised Losi retailers like RC Model Shop. Genuine Losi components are manufactured to exacting standards and come with the assurance that they will fit and function perfectly with your Promoto-MX. When purchasing from an authorised retailer, you can be confident you're receiving an authentic component backed by the Losi warranty and quality guarantee.
