- True to Scale Supermoto-Inspired Appearance — The rim is designed with authentic supermoto motorcycle styling that perfectly complements the Promoto-SM's compact, aggressive proportions. This visual authenticity appeals to riders who appreciate the finer details of their RC machines and want their setup to look as impressive as it performs.

This engineering approach ensures the rim maintains its structural integrity through countless hard landings, jumps and rough terrain encounters that are typical in RC supermoto riding.

Technical Performance
The PRO 1/4 Pro-Spec Aluminum Rear Rim represents Pro-Line Racing's commitment to engineering excellence in the RC aftermarket. Machined from 6061 billet aluminium rather than cast, this rim offers superior strength-to-weight ratio and consistent quality across every unit produced. The anodised finish provides a hard, protective layer that resists oxidation and maintains the rim's appearance through mud, water and salt-laden environments — important for UK RC enthusiasts who often encounter variable weather conditions. The V2 Bead SM Mounting Sleeve compatibility ensures the rim integrates perfectly with the Promoto-SM's wheel assembly, providing secure fitment that prevents slippage during aggressive acceleration or braking. For riders upgrading their Promoto-SM or building a high-performance machine from the ground up, this rear rim is a crucial component that contributes to overall handling, responsiveness and aesthetic appeal. The precision engineering typical of Pro-Spec components means you're investing in a part that will maintain its appearance and structural integrity for years of riding pleasure.
