Key Features
- True to Scale Supermoto-Inspired Appearance — The wheel design accurately replicates full-size supermoto motorcycle wheels, giving your 1/4 scale RC motorcycle an authentic, competitive look that turns heads at the track or club.
- Pre-Assembled and Ready to Run — This wheel arrives completely pre-assembled with the rim, spokes and hub already fitted together, meaning you can mount it straight onto your motorcycle without any assembly work or additional tuning required.
- Factory Laced and Precisely Trued — The spokes are professionally factory-laced and trued during manufacturing, ensuring perfect balance and concentricity from day one, which translates directly to smoother handling and more stable performance compared to wheels that require manual assembly.
- CNC Machined 6061 Billet Aluminium Hub and Rim — The use of aerospace-grade 6061 billet aluminium, machine-cut using precision CNC equipment, creates a wheel that is significantly stronger and lighter than plastic alternatives, whilst maintaining perfect tolerances for reliable performance.
- Anodised Finish for Durability — The anodised surface treatment provides corrosion resistance and scratch protection, keeping the wheel looking fresh and maintaining its structural integrity even after repeated exposure to dirt, water and challenging riding conditions.
- Zinc-Plated Steel Spokes — The spokes are zinc-plated for enhanced corrosion resistance and durability, with a maximum torque specification of 4 kg/cm (358 oz/in), ensuring they can handle the demands of serious RC motorcycle racing without failure or spoke loosening.
- Precisely Engineered Spoke Angle Geometry — Every aspect of the spoke angle and geometry has been precisely engineered to optimise structural integrity, load distribution and visual authenticity, delivering professional-grade engineering in a 1/4 scale component.
- V2 Bead Nylon Tire Mounting Sleeve — The wheel includes a nylon V2 Bead tire mounting sleeve that provides a robust and reliable glue-bond for pre-mounting Pro-Line V2 Bead MX tyres, enabling quick and convenient tire changes without damaging the wheel or rim.
- Convenient Glueless Tire Changing — The mounting sleeve system allows you to pre-mount your tyres and simply swap them onto the wheel as needed, eliminating the need for repeated gluing and reducing downtime when changing tyre compounds or conditions.
- Replacement Parts Availability — Pro-Line offers replacement hub, rim and spoke components available separately, allowing you to repair damage, customise colours or build wheels in different colour combinations without replacing the entire wheel assembly.
- Designed for Losi Promoto-SM Compatibility — This wheel is specifically engineered and tested for compatibility with the Losi Promoto-SM 1/4 scale supermoto motorcycle, ensuring perfect fit and optimal performance with your motorcycle.
Technical Performance
The Pro-Spec Aluminium V2 Bead Rear Wheel represents a significant step forward in 1/4 scale RC motorcycle wheel technology. The construction uses anodised 6061 billet aluminium for both the hub and rim, a material choice that delivers exceptional strength-to-weight ratio compared to plastic or cast alternatives. The wheel is manufactured using precision CNC machinery, ensuring that every component maintains exact tolerances and concentricity specifications. The zinc-plated steel spokes are factory-laced and precisely trued during the manufacturing process, meaning the wheel arrives in perfect condition without any run-out or wobble. This precision engineering translates directly into superior handling characteristics and more predictable performance on track or at the field. The spoke angle geometry has been precisely engineered to optimise load distribution and structural integrity, preventing spoke failure under the stresses of aggressive riding. The maximum torque specification of 4 kg/cm (358 oz/in) provides a clear benchmark for spoke tightness, ensuring even tension and preventing loose spokes that could cause vibration or handling issues. The anodised finish provides enhanced durability and corrosion resistance compared to bare aluminium, protecting the wheel from the elements and maintaining its appearance through multiple riding seasons. The V2 Bead nylon mounting sleeve enables use with Pro-Line V2 Bead SM tyres exclusively, creating a complete system optimised for Promoto-SM performance. The wheel is compatible with both the Losi 1/4 Promoto-SM FXR Supermoto Motorcycle RTR (Battery and Charger Included) and the Losi 1/4 Promoto-SM FXR Supermoto Motorcycle RTR Basic, making it a universal rear wheel upgrade for Promoto-SM owners across the UK RC motorcycle community.

Frequently Asked Questions
- Will this Pro-Spec wheel work with my Promoto-SM motorcycle? — Yes, the Pro-Line Pro-Spec Aluminium V2 Bead Rear Wheel is specifically engineered for the Losi Promoto-SM 1/4 scale supermoto motorcycle. It is compatible with both the Losi Promoto-SM FXR RTR and Losi Promoto-SM FXR RTR Basic models, making it a direct fit upgrade for your existing motorcycle.
- What tyres do I need to use with this wheel? — This wheel is compatible exclusively with Pro-Line V2 Bead SM tyres. The wheel features a V2 Bead nylon mounting sleeve that bonds reliably with Pro-Line V2 Bead SM tyres. Using tyres from other manufacturers or different bead styles may result in poor tyre fitment or performance issues.
- How do I mount a tyre to this wheel? — The wheel includes a nylon V2 Bead mounting sleeve that provides a glue-bond interface for your tyre. When inserting the wheel into the mounting sleeve, you should first mock the tyre direction to ensure correct orientation. Align the groove pins on the rim to the same side as the mounting sleeve groove—if the rim pin is on the right, the mounting sleeve groove should also be on the right. Once aligned correctly, apply adhesive to bond the tyre to the mounting sleeve. The system enables convenient glueless tyre changing once the initial bond is set.
- Do I need to assemble this wheel, or does it arrive ready to use? — The Pro-Spec Aluminium V2 Bead Rear Wheel arrives completely pre-assembled and ready to mount onto your motorcycle. The rim, spokes and hub are already fitted together, factory-laced and precisely trued. There is no assembly work required—you simply need to mount your tyre and install the wheel onto your motorcycle.
- What makes this wheel better than the plastic wheels on my stock Promoto-SM? — The Pro-Spec Aluminium wheel delivers superior durability, authenticity and performance compared to basic plastic wheels. The anodised 6061 billet aluminium construction is significantly stronger and lighter than plastic, whilst the CNC machining and factory lacing ensure precision tolerances that plastic wheels cannot match. The zinc-plated steel spokes resist corrosion and can be precisely trued, and the anodised finish provides enhanced protection against the elements. Most importantly, the precision engineering translates into noticeably smoother handling, more stable performance and a genuinely authentic supermoto appearance.
- Can I replace just the spokes if I damage one? — Yes, Pro-Line offers replacement hub, rim and spoke components available separately. If you damage a spoke, you can purchase a replacement spoke rather than replacing the entire wheel assembly, making repairs more cost-effective and enabling customisation if desired.
- What is the maximum torque for the spokes? — The zinc-plated steel spokes are rated for a maximum torque of 4 kg/cm or 358 oz/in. This specification ensures that you can tension the spokes appropriately without over-tightening and damaging the spokes or the wheel structure.
- Is this wheel available in other colours? — Yes, the Pro-Spec Aluminium V2 Bead wheels are available in a variety of colours to match your bike plastics. The Black/Red colour scheme offered here is designed to complement modern Promoto-SM plastics, but Pro-Line offers alternative colour options to suit different aesthetic preferences.
- Will this wheel fit a Promoto-MX motorcycle? — No, this wheel is specifically designed for the Promoto-SM and will not fit a Promoto-MX. Pro-Line offers separate Pro-Spec Aluminium wheels designed specifically for the Promoto-MX model line, so ensure you select the correct wheel variant for your motorcycle.
