Product Details
This 7075 aluminium Knuckle and Pull Rod offers better strength and durability over the stock plastic part for those pushing the limits with their Promoto-MX. It features six ball bearings which ensure smooth operation over the standard brass bushings. Anodized to offer an added level of durability and personalisation and to finish it off the 'RC Overhaul' logo is laser etched onto the part that adds a smart small detail that makes your bike stand out from the rest.
Overview
The RC Overhaul Aluminum Knuckle & Pull Rod is a premium upgrade component designed specifically for the Losi 1/4 Promoto-MX motorcycle and Promoto-SM Supermoto models. If you're serious about pushing your RC motorbike to its limits, this is an essential upgrade that transforms the handling and durability of your machine. Whether you're a dedicated RC enthusiast in the UK looking to enhance your Promoto or a racer seeking competitive advantages, this aluminium knuckle and pull rod assembly delivers the strength, precision and longevity that stock plastic components simply cannot match. Built by RC Overhaul, a specialist in high-performance RC upgrades, this component represents a significant step up from factory parts.
The transition from plastic to aluminium is one of the most impactful upgrades you can make to any RC vehicle, and the Promoto-MX is no exception. Stock plastic knuckles and pull rods flex under load, absorb impact poorly and can crack or break during aggressive riding. The RC Overhaul upgrade addresses these weaknesses comprehensively, giving you the confidence to ride harder, faster and more aggressively without fear of catastrophic failure. This is the kind of upgrade that separates casual bashers from committed RC enthusiasts who demand reliability and performance from their machines.
Every detail of this component has been engineered for excellence, from the choice of material through to the finishing touches. The anodised blue finish isn't just for aesthetics—it provides genuine protective benefits whilst the laser-etched RC Overhaul logo adds a professional touch that makes your bike stand out from the rest. If you're building a high-performance RC motorcycle setup or maintaining a competition-grade machine, the RC Overhaul Aluminum Knuckle & Pull Rod is the upgrade you've been looking for.
Key Features
- 7075 Aluminium Construction — This premium aircraft-grade aluminium alloy is renowned for its exceptional strength-to-weight ratio and superior durability compared to standard materials. 7075 aluminium is significantly stronger than the plastic used in stock components, allowing it to withstand the intense forces generated during aggressive riding, hard landings and competitive use without flexing or breaking.
- Six Ball Bearings for Smooth Operation — The assembly features six integrated ball bearings that replace the standard brass bushings found on stock parts. Ball bearings provide dramatically smoother, lower-friction motion with virtually no drag, ensuring precise steering response and improved overall handling characteristics. This upgrade transforms the feel of your RC motorcycle, delivering professional-grade steering feedback and responsiveness that competitive riders demand.
- Anodised Blue Finish — The premium anodised blue coating provides multiple benefits beyond visual appeal. Anodising creates a hard, corrosion-resistant surface that protects the aluminium from oxidation and wear, extending the lifespan of the component significantly. The vibrant blue finish also offers excellent personalisation options, allowing you to customise your RC motorcycle's appearance whilst gaining genuine protective benefits.
- Laser-Etched RC Overhaul Branding — Each component features a precision laser-etched RC Overhaul logo that adds a premium, professional appearance to your machine. This small detail demonstrates the quality commitment of RC Overhaul and adds a touch of class that distinguishes upgraded builds from stock machines. The laser etching is permanent and won't wear away with use, maintaining its appearance indefinitely.
- Direct Upgrade from Stock Components — This assembly is engineered as a direct replacement for the standard plastic knuckle and pull rod, making installation straightforward for anyone with basic RC maintenance experience. The upgrade path is clear and efficient, allowing you to enhance your Promoto without requiring additional modifications or complications.
Technical Performance
The engineering behind this component reflects years of RC motorcycle development and real-world testing. The choice of 7075 aluminium is deliberate and significant—this is the same material used in aerospace applications where strength and reliability are absolutely non-negotiable. The material provides rigidity that prevents the flex and deflection inherent in plastic parts, which directly translates to more predictable handling, better steering response and improved overall control during aggressive riding. The six ball bearings represent a quantum leap in steering precision over traditional brass bushings; they reduce friction by a remarkable margin, meaning your steering inputs translate more directly into responsive cornering without the dead zones and resistance that plague stock setups. When you're piloting a 1/4 scale RC motorcycle at speed around a circuit or through challenging terrain, this level of steering precision becomes absolutely critical. The anodised finish isn't merely cosmetic—it's a functional upgrade that hardens the surface of the aluminium, increasing resistance to impact damage, corrosion from moisture and wear from repeated use. Every aspect of this component's design prioritises durability and performance, making it an investment that pays dividends through countless hours of reliable operation.

- What makes aluminium better than the stock plastic part? — Aluminium offers dramatically superior strength, durability and rigidity compared to plastic. Plastic components flex under load and can crack or break during aggressive riding, whilst 7075 aluminium maintains its shape under stress, providing more predictable handling, better steering response and significantly longer service life. For serious RC enthusiasts who push their machines hard, upgrading to aluminium is transformative.
- Will this upgrade improve my steering response? — Absolutely. The six ball bearings integrated into this assembly dramatically reduce friction compared to the standard brass bushings, meaning your steering inputs translate more directly and precisely into motorcycle movement. You'll notice sharper cornering response, more predictable handling characteristics and better overall control, particularly during high-speed runs and competitive use.
- Is installation difficult? — Installation is straightforward for anyone with basic RC motorcycle maintenance experience. This component is a direct replacement for the stock knuckle and pull rod assembly, meaning it uses the same mounting points and requires no additional modifications. Most experienced RC enthusiasts can complete the upgrade in under 30 minutes with standard tools.
- Why choose RC Overhaul over other manufacturers? — RC Overhaul specialises in high-performance upgrades for RC motorcycles and brings genuine expertise to component design and manufacturing. The choice of 7075 aluminium, integration of six ball bearings, anodised finish and attention to detail like the laser-etched branding all demonstrate a commitment to quality that distinguishes RC Overhaul products from budget alternatives. When you're investing in an upgrade, you want it from a manufacturer who understands the demands of serious RC riding.
- Will the anodised blue colour match my motorcycle? — The vibrant anodised blue finish complements both blue and red Promoto models beautifully, offering both visual cohesion and premium appearance. Even if your motorcycle body colour differs slightly, the professional appearance of the anodised upgrade components elevates the overall aesthetic of your machine.
