Technical Performance
The Lean Bar Wheels and Bump Stops represent critical suspension components on the Promoto-SM supermoto motorcycle. The rubber construction of both the wheels and stops provides the necessary compliance and damping characteristics that allow the Promoto-SM's innovative lean suspension to function correctly. When the motorcycle leans into corners, the lean bar system allows the chassis to tilt whilst maintaining directional control, and these rubber components are essential for controlling the rate of suspension travel and preventing harsh bottoming. Over time, rubber components compress and harden through repeated use, affecting the suspension feel and cornering stability. This replacement pack, supplied with six wheels and six stops, allows you to completely refresh the system. The SM specification wheels are engineered specifically for the Promoto-SM's geometry and track width requirements, ensuring that suspension alignment and handling remain optimised. For UK RC enthusiasts running their Promoto-SM models regularly, having replacement rubber components on hand is essential maintenance practice, ensuring consistent performance session after session and maintaining the responsive handling that makes supermoto-style RC motorcycles so popular in the competitive and recreational RC community.

Frequently Asked Questions
- What is the Lean Bar system on the Promoto-SM? — The Lean Bar is the Promoto-SM's unique suspension system that allows the motorcycle body to lean into corners realistically, similar to a full-size supermoto. The wheels and stops control suspension travel and return, which is why replacing worn rubber components is essential for maintaining handling.
- How often should I replace these Lean Bar components? — This depends on usage frequency and driving intensity. Heavy regular use at tracks or during competitive driving may require replacement every few months, whilst recreational use might extend intervals to six months or longer. When you notice the bike feels less responsive in corners or suspension feel changes, replacement is recommended.
- Will these parts fit my Promoto-SM? — Yes, these Z-LOS-2288 parts are confirmed compatible with both Promoto-SM FXR RTR variants: the C-LOS-2272 Promoto-SM FXR Supermoto Motorcycle RTR Basic and the C-LOS-2310 Promoto-SM FXR Supermoto Motorcycle RTR with Battery and Charger Included.
- Are these rubber wheels the same as regular RC car wheels? — No, these are specifically engineered for the Promoto-SM's lean suspension system and are not compatible with other RC vehicle types. They function as both suspension components and lean bar guides rather than rolling wheels in the traditional sense.
- Can I use non-Losi replacement components? — Whilst aftermarket options may exist, genuine Losi components ensure perfect fitment, correct suspension geometry and the handling characteristics the Promoto-SM was engineered to deliver. Using authentic parts is recommended for optimal performance and longevity.
- How difficult is installation? — Replacement is straightforward for anyone familiar with basic RC maintenance. The components simply replace worn parts in the existing lean bar assembly without requiring special tools, although consulting the Promoto-SM manual is recommended for first-time installation.
