Technical Performance
This front wheel represents the pinnacle of 1/4 scale RC motorcycle wheel engineering. The anodised 6061 billet aluminium construction provides the ideal balance between rigidity and weight, essential for maintaining steering precision and accelerating quickly without excessive unsprung mass. The CNC machining process ensures that every hub and rim is produced to identical specifications, eliminating variances that could affect handling or aesthetics. The zinc-plated steel spokes are rated to a maximum torque of 4 kilograms per centimetre (358 ounces per inch), providing substantial strength whilst allowing for precise spoke truing if adjustment becomes necessary during the wheel's lifespan. The factory-laced and trued construction means the wheel arrives perfectly balanced, eliminating vibration and ensuring smooth, predictable handling characteristics. The precisely engineered spoke angle geometry is calculated to distribute forces evenly across the wheel structure, maximising durability during aggressive cornering, acceleration and braking. The V2 Bead mounting sleeve system is engineered to work exclusively with Pro-Line V2 Bead SM tyres, creating a secure and reliable connection that maintains tyre positioning under all riding conditions. The 4.0-inch inner tyre diameter accommodates the correct tyre sizes for 1/4 scale supermoto riding, ensuring proper gearing ratios and handling balance. The anodised finish protects the aluminium from corrosion, oxidation and weathering, maintaining the wheel's appearance and structural integrity through countless riding sessions whether on carpet, asphalt or outdoor terrain.

Installation and Mounting Tips
When installing your tyre onto the V2 Bead mounting sleeve, it's important to mock the tyre direction before applying any adhesive to ensure proper fitment and appearance. Align the groove pins on both the rim and the mounting sleeve to the same side — if the rim pin is on the right, the mounting sleeve groove should also be positioned on the right. This alignment ensures that your tyre sits correctly and maintains optimal balance. Pro-Line provides a 3D-printable lacing fixture tool (available as an STL file download) to assist with spoke replacements if you ever need to repair or customise your wheel. Please note that Pro-Spec Aluminium Wheels for the Promoto-SM work exclusively with Pro-Line V2 Bead SM tyres only — ensure you're using the correct tyre specification to guarantee proper fitment and performance.
Frequently Asked Questions
- What is the V2 Bead system and why does it matter? — The V2 Bead system is Pro-Line's tyre mounting technology that uses a nylon mounting sleeve to create a secure glue-bond connection between tyre and wheel. This system is superior to traditional gluing methods because it allows you to pre-mount your tyre to the sleeve and then swap it onto the wheel as needed, reducing the time spent on tyre changes and eliminating the need for additional adhesive during routine maintenance.
- Are these wheels suitable for beginners? — Yes, these wheels are suitable for RC enthusiasts of all skill levels. As a pre-assembled, factory-trued component, they require no special expertise to install — simply bolt them onto your Promoto-SM and mount your V2 Bead tyres. However, these are premium performance wheels, so they're especially appreciated by experienced riders who understand the value of precision engineering and authentic scale appearance.
- What makes these Pro-Spec wheels different from standard wheels? — Pro-Spec wheels are manufactured from premium 6061 billet aluminium using CNC machining, then anodised for durability and appearance. They feature factory-laced and precisely trued spokes, ensuring perfect balance and consistency from the moment they leave the factory. Standard wheels may use cheaper materials or production methods that result in variances. These Pro-Spec wheels are a significant upgrade in terms of both performance and visual authenticity.
- Can I use these wheels with other tyres? — No, these wheels are designed specifically to work with Pro-Line V2 Bead SM tyres only. The V2 Bead mounting sleeve system is proprietary to Pro-Line and engineered to work exclusively with their compatible tyre range. Using other tyre brands or specifications could result in poor fitment, unreliable mounting and compromised handling.
- Are replacement spokes available if I break one? — Yes, Pro-Line offers replacement hubs, rims and spokes available separately, so if you ever damage a spoke or need to customise your wheel's appearance, individual components can be purchased for repairs or custom colour combinations.
- What is the maximum torque rating? — The zinc-plated steel spokes are rated to a maximum torque of 4 kilograms per centimetre or 358 ounces per inch, providing substantial strength for high-performance riding whilst remaining light enough to minimise unsprung mass.
- Will these wheels work on my Promoto-MX? — These wheels are specifically designed for the Losi Promoto-SM supermoto model. Whilst Pro-Line does offer similar Pro-Spec wheels for the Promoto-MX motocross model, you should verify compatibility with your specific motorcycle variant before purchasing, as the mounting systems and tyre sizes may differ.
