Key Features
- 7075 Aluminium Construction — This aerospace-grade aluminium alloy is significantly stronger and more durable than the plastic components found in stock Promoto-MX machines, ensuring the knuckle and pull rod assembly can withstand the extreme forces generated during aggressive riding, high-speed cornering and competitive racing without risk of failure or damage.
- Six Ball Bearings for Smooth Operation — The assembly features six precision ball bearings throughout the joint, delivering substantially smoother and more responsive steering geometry compared to the standard brass bushings found in stock components, resulting in improved handling precision and reduced friction during operation.
- Anodised Red Finish — The hard-anodised red coating provides multiple benefits: enhanced durability against corrosion and oxidation, extended component lifespan, and a vibrant aesthetic that personalises your RC motorcycle with a professional, premium appearance.
- Laser-Etched RC Overhaul Branding — The RC Overhaul logo is precision laser-etched directly onto the component, adding an exclusive custom detail that distinguishes your machine from standard builds and demonstrates your commitment to quality parts and serious RC performance.
- Precision Engineering — Every aspect of this component has been engineered to exacting standards, ensuring perfect fitment with your Promoto-MX and maintaining the precise steering geometry and suspension kinematics your machine depends on for optimal performance.
Technical Performance
The RC Overhaul Aluminium Knuckle & Pull Rod represents a quantum leap in build quality and performance over factory plastic components. Manufactured from 7075 aluminium—the same material used in high-performance aerospace and motorsport applications—this assembly delivers exceptional strength-to-weight ratio without adding unnecessary bulk to your machine. The six ball bearings integrated throughout the knuckle and pull rod joints eliminate the friction and play inherent in brass bushing designs, resulting in steering response that feels noticeably sharper and more precise. Where standard brass bushings gradually wear and develop play over repeated use, causing your steering to feel vague and imprecise, the ball bearing design maintains consistent performance session after session. The hard-anodised finish isn't merely cosmetic; it's a critical protective layer that shields the aluminium from the corrosive effects of moisture, dirt and the oxidation that can degrade exposed metal surfaces. This engineering attention to detail translates directly into extended component lifespan and maintained performance over many seasons of use. Every knuckle and pull rod assembly is precision-manufactured to maintain the exacting steering geometry your Promoto-MX requires, ensuring that when you install this upgrade, your machine's handling characteristics remain optimised for both racing and recreational riding.

Frequently Asked Questions
- Is the RC Overhaul Knuckle & Pull Rod compatible with my Losi Promoto-MX? — Yes, this component is specifically engineered for compatibility with multiple Promoto-MX variants including the Losi 1/4 Promoto-MX Motorcycle RTR FXR (Red), the Pro Circuit model, the Club MX (Blue) variant, and the Losi 1/4 Promoto-SM FXR Supermoto Motorcycle RTR. Check your specific model number to confirm compatibility before ordering.
- What advantages does the 7075 aluminium offer over plastic? — 7075 aluminium is an aerospace-grade material significantly stronger and more durable than plastic, resisting impact damage, bending and deformation that can occur during aggressive riding. This means your knuckle and pull rod assembly will maintain its geometry and precision through years of use, whereas plastic components eventually flex, crack or break under sustained performance demands.
- Why do ball bearings matter compared to brass bushings? — Ball bearings rotate with dramatically lower friction than brass bushings, resulting in noticeably smoother steering response, faster turn-in, and more consistent handling throughout your riding session. As brass bushings wear over time, they develop play and looseness that makes steering feel imprecise; ball bearings maintain consistent performance indefinitely with proper maintenance.
- Will this upgrade improve my lap times? — The improved steering precision and reduced friction from the ball bearing design, combined with the more responsive geometry enabled by the rigid aluminium construction, will contribute to sharper handling and more predictable steering response. For competitive riders, these improvements translate to more consistent cornering speed and better overall machine control.
- Is installation difficult? — Installation requires basic RC maintenance skills and appropriate tools. If you're comfortable performing routine maintenance on your Promoto-MX, you'll be able to install this component. If you're unsure, our expert team at RC Model Shop can provide guidance—contact us for detailed installation support.
- Does the red colour match my Promoto-MX? — The anodised red finish is specifically designed to coordinate with red Promoto-MX models, though it will integrate well with most colour schemes. If you prefer a different colour, RC Overhaul also manufactures versions in blue and black.
