Frequently Asked Questions
- Is this a genuine Pro-Line Racing product? — Yes, this is an authentic Pro-Line Racing Pro-Spec Aluminium Front Hub manufactured to the brand's exacting standards. The model number PRO284704 is the official Pro-Line Racing designation, and purchasing from RC Model Shop ensures you receive a genuine component with proper warranty and support.
- What Promoto-SM models does this hub fit? — This front hub is specifically designed for the Losi Promoto-SM 1/4 scale motorcycle when used with the Pro-Spec Aluminium SM Front Rim with spokes. Always verify compatibility before purchasing replacement components to ensure proper fitment and performance.
- What is the difference between the gold and red Pro-Spec hubs? — Pro-Line Racing offers this Pro-Spec Aluminium Front Hub in multiple anodised colour finishes, including gold (PRO284704) and red (PRO284703). The functional performance and engineering are identical between colours; the difference is purely aesthetic. Choose the colour that matches your Promoto-SM's overall appearance and your personal style preferences.
- Why is this hub made from 6061 aluminium? — 6061 is an aerospace-grade aluminium alloy chosen specifically because it offers the best combination of strength, lightweight properties, machinability and corrosion resistance. This material can handle the stresses of 1/4 scale RC riding whilst remaining light enough to not negatively impact performance. It machines to precise tolerances better than other materials, ensuring perfect fitment every time.
- How does the hard-anodised finish improve durability? — The hard-anodised finish creates a protective oxide layer on the aluminium surface that resists corrosion from moisture and salt spray, prevents scuffing and scratching from impacts and crashes, and maintains the gold colour for years. This finish is standard on professional-grade RC components and dramatically extends the lifespan of the hub compared to bare or soft-anodised aluminium.
- Is this suitable for beginners? — This is a replacement component rather than a complete bike, so it's best suited to owners of the Losi Promoto-SM who need to replace a damaged or worn front hub. Beginners should start with a complete ready-to-run Promoto-SM kit before considering individual component upgrades.
- Can I use this hub with standard rims? — No, this Pro-Spec Aluminium Front Hub is engineered specifically for the Pro-Spec Aluminium SM Front Rim with spokes. Using it with other rim designs may result in fitment issues, poor wheel balance or performance problems. Always use genuine matched components.
- What tools do I need to install this hub? — Installation requirements will depend on your current wheel assembly setup. Pro-Line Racing provides detailed assembly instructions with this component, and you may need basic RC tools such as hex drivers and bearing tools. Consult the manual or contact RC Model Shop for detailed installation guidance.
