Key Features
- True to Scale Supermoto-Inspired Appearance — The wheel design captures the authentic look of full-size supermoto motorcycle wheels, giving your Promoto-SM a genuine, professional appearance that stands out on the track or at the skate park.
- Pre-Assembled and Ready to Run — The wheel comes complete with rim, spokes and hub already assembled, meaning you can fit your V2 Bead tyres and start riding immediately without requiring additional setup or building work.
- Factory Laced and Trued — Each wheel has been precisely laced and trued at the factory, ensuring perfect concentricity and alignment that directly translates to smooth, predictable handling during cornering and acceleration.
- Anodized CNC Machined 6061 Billet Aluminum Hub and Rim — The hub and rim are manufactured from premium 6061 billet aluminum using CNC machining, then anodized for corrosion resistance and durability, ensuring the wheels will maintain their appearance and structural integrity through countless sessions.
- Precisely Engineered Spoke Angle Geometry — The spoke angles have been calculated and engineered to optimise strength whilst maintaining light weight, providing the perfect balance between durability and performance for supermoto-style riding.
- Zinc-Plated Steel Spokes for Durability — The spokes are manufactured from steel and zinc-plated for corrosion resistance, featuring a maximum torque rating of 4 Kg/cm (358 oz/in), providing the strength needed for aggressive riding whilst remaining easy to true if repairs become necessary.
- Nylon V2 Bead Tire Mounting Sleeve — The included nylon mounting sleeve provides a robust and reliable glue-bond for secure tyre mounting, whilst the V2 Bead design allows for convenient glueless tyre changing, saving you time during pit stops and maintenance.
- Convenient Glueless Tire Changing Capability — Unlike traditional methods, the V2 Bead system allows you to swap tyres quickly without needing to apply new glue every time, keeping you riding instead of spending hours in the workshop.
- Replacement Parts Available — Replacement hubs, rims and spokes are available separately for repairs or custom colour combinations, allowing you to maintain your wheels indefinitely and experiment with different colour schemes to match your bike's plastics.

Technical Performance
The Pro-Spec Aluminum V2 Bead Front Wheel represents the pinnacle of precision engineering for 1/4 scale RC motorcycle wheels. Manufactured from premium 6061 billet aluminum with anodized finish, the hub and rim offer exceptional strength-to-weight ratio and corrosion resistance that ensures long-term durability even in outdoor environments. The wheel diameter measures 4.0 inches, sized perfectly for the Promoto-SM platform. The zinc-plated steel spokes are factory-laced and trued to precise tolerances, engineered with optimised spoke angle geometry that maximises strength whilst minimising rotational mass. With a maximum torque rating of 4 Kg/cm (358 oz/in), these spokes can handle aggressive cornering forces and acceleration without deformation. The nylon V2 Bead mounting sleeve provides a reliable interface for tyre mounting, enabling secure glue-bonding whilst allowing tool-free tyre changes when swapping between rubber compounds. The complete pre-assembled design eliminates the need for spoke tensioning or wheel truing during initial setup, delivering a bolt-on component ready for immediate use. The anodized finish over the CNC-machined aluminum provides excellent corrosion protection, ensuring these wheels maintain their cosmetic appeal and structural integrity through seasons of use. Whether you're running laps at high speed or practising technical supermoto manoeuvres, these wheels deliver the precision and reliability demanded by serious RC motorcycle enthusiasts.

Frequently Asked Questions
- Which RC motorcycle models are these wheels compatible with? — These Pro-Spec Aluminum V2 Bead Front Wheels are designed specifically for the Losi Promoto-SM supermoto motorcycle. They are also compatible with related models in the Promoto range, including the Losi 1/4 Promoto-SM FXR Supermoto Motorcycle RTR variants. However, they are not compatible with MX models—if you own a Promoto-MX, you'll need the Pro-Spec Aluminum V2 Bead Front Wheel designed specifically for that platform.
- What tyres do these wheels require? — These wheels work exclusively with Pro-Line V2 Bead SM tyres. The V2 Bead mounting sleeve is engineered specifically for Pro-Line's SM tyre range, and using other tyre brands or styles may result in poor fit and performance. This compatibility ensures optimal performance and reliability.
- How do I mount tyres to these wheels? — The wheels feature a nylon V2 Bead mounting sleeve that allows for both traditional glue-bonded mounting and convenient glueless tyre changes. When inserting the wheel into the mounting sleeve, you should mock the tyre direction before gluing and align the groove pins to the same side—if the rim pin is on the right, the mounting sleeve groove should be on the right as well. This ensures proper alignment and balanced rotation.
- Can I replace individual spokes if one breaks? — Yes, Pro-Line offers replacement hubs, rims and spokes available separately for repairs or custom colour combinations. Additionally, Pro-Line provides a 3D printable lacing fixture tool to assist with spoke replacements, available as a free STL file download. This means you can repair your wheels indefinitely rather than needing to purchase complete replacements.
- What is the maximum torque these spokes can handle? — The zinc-plated steel spokes are rated for a maximum torque of 4 Kg/cm or 358 oz/in, providing substantial strength for aggressive riding whilst remaining serviceable if adjustments become necessary.
- Are these wheels suitable for beginners? — Whilst these are professional-grade wheels designed for serious enthusiasts, the pre-assembled and ready-to-run nature makes them suitable for riders at all levels. If you already own a Promoto-SM and are looking to upgrade from stock wheels, these represent an excellent step forward in appearance and performance.
- What makes these wheels different from standard wheels? — The Pro-Spec designation indicates these are premium wheels featuring CNC-machined billet aluminum construction with anodized finish, factory-laced and trued spokes with optimised geometry, and a professional-grade appearance that captures authentic supermoto styling. They are engineered for enthusiasts who demand durability, precision and realism from their RC motorcycles.
- Can I use these wheels on other Losi motorcycle models? — No, these front wheels are specifically designed for the Promoto-SM. The Promoto-MX uses different Pro-Spec wheels (model G-PRO283600T1), so you must ensure you order the correct version for your motorcycle.
