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 Aluminium Knuckle & Pull Rod is a precision-engineered upgrade component designed specifically for the Losi Promoto-MX 1/4 scale supermoto motorcycle. This front-end hardware assembly transforms your RC motorcycle's handling and durability, making it an essential upgrade for serious riders in the UK RC hobby community. Whether you're tackling aggressive riding styles or simply want to enhance your Promoto-MX performance, this silver anodised component delivers the strength and smoothness that separates casual bashers from dedicated RC enthusiasts.
Built from aerospace-grade 7075 aluminium, this knuckle and pull rod assembly replaces the stock plastic components with metal precision engineering that can withstand the demands of high-performance RC riding. The six integrated ball bearings ensure smooth, consistent motion with virtually no play or resistance, a dramatic improvement over standard brass bushings found in original equipment. This means better steering response, more predictable handling, and a noticeably improved riding experience from the moment you bolt it on to your Promoto-MX.
Available in a striking silver finish with laser-etched RC Overhaul branding, this upgrade combines functional excellence with visual appeal. RC car enthusiasts and Promoto owners across the UK trust RC Overhaul components for their reliability and performance. If you're pushing your RC motorcycle hard or simply want the best-in-class front-end hardware, this is the upgrade you've been looking for.
Key Features
- 7075 Aluminium Construction — Precision machined from aerospace-grade 7075 aluminium, this knuckle and pull rod assembly offers significantly better strength and durability compared to the stock plastic components, meaning it can handle aggressive riding without flexing, cracking, or breaking during use.
- Six Integrated Ball Bearings — Rather than relying on standard brass bushings, this assembly features six precision ball bearings that deliver smooth, frictionless operation with zero play, resulting in more responsive steering input and better overall handling characteristics.
- Anodised Silver Finish — The hard-anodised silver coating provides superior corrosion and wear resistance while adding a premium, personalised appearance that makes your Promoto-MX stand out from the rest of the field.
- Laser-Etched Branding — A precisely laser-etched RC Overhaul logo adds a refined finishing touch that demonstrates attention to detail and quality craftsmanship in every component.
- Drop-In Compatibility — Designed as an option part for the Losi Promoto-MX, this assembly integrates seamlessly with your existing setup without requiring additional modifications or adaptations.
- Improved Steering Response — The combination of rigid aluminium construction and ball bearing smoothness delivers noticeably sharper steering response and more predictable handling, giving you greater confidence and control when pushing your RC motorcycle to the limits.
Technical Performance
This knuckle and pull rod assembly represents a significant upgrade in front-end engineering for your Promoto-MX. The use of 7075 aluminium—the same material specification used in aerospace and professional motorsport applications—provides exceptional strength-to-weight ratio and rigidity that the original plastic components simply cannot match. Where the stock part flexes under cornering loads and aggressive steering inputs, this machined aluminium assembly maintains perfect geometry and precise alignment. The six ball bearings are the real performance secret here; each bearing spins independently on precision steel races, virtually eliminating friction and play. This means steering inputs translate directly to wheel movement without lag or dead zones. In comparison, brass bushings (used in original equipment) create measurable resistance and allow micro-movements that accumulate into sloppy handling. For anyone serious about Promoto-MX performance, the difference is immediately apparent in how the bike responds to your inputs and maintains consistent handling across multiple runs. The anodised surface treatment isn't just for looks—it actually creates a hard ceramic layer that resists wear from constant use and protects the underlying aluminium from oxidation and corrosion. Whether you're riding in dry conditions or damp UK weather, this component will maintain its performance and appearance for years of reliable service.

Frequently Asked Questions
- Is the RC Overhaul Aluminium Knuckle & Pull Rod compatible with my Losi Promoto-MX? — Yes, this assembly is specifically designed as an option upgrade part for the Losi Promoto-MX. It drops in directly as a replacement for the stock plastic front-end hardware without requiring any modifications or additional parts.
- What is the advantage of aluminium over the stock plastic components? — Aluminium provides dramatically better strength and rigidity than plastic, meaning it won't flex or deflect under aggressive riding loads. Additionally, the 7075 grade used here is aerospace-specification material that offers superior durability and longevity even with frequent, hard use.
- Why are the six ball bearings better than brass bushings? — Ball bearings provide near-frictionless rotation with zero play, whereas brass bushings create measurable resistance and allow micro-movements that reduce steering precision. The difference in handling response is immediately noticeable when you ride—steering inputs feel sharper and more direct.
- Will this upgrade improve my Promoto-MX handling? — Yes, significantly. The combination of rigid aluminium construction and smooth ball bearing operation delivers noticeably sharper steering response, more predictable handling, and greater confidence when pushing your RC motorcycle hard. You'll feel the improvement from your first run.
- Is the anodised finish durable? — The hard-anodised silver coating is specifically designed for durability and wear resistance. It protects the underlying aluminium from corrosion and maintains both performance and appearance through extended use in various UK riding conditions.
- Do I need any tools to install this component? — Installation requirements depend on your existing setup and mechanical familiarity. We recommend consulting the assembly instructions or contacting our RC Model Shop team for guidance on installation procedures specific to your Promoto-MX.
- What makes RC Overhaul components different from other upgrade manufacturers? — RC Overhaul focuses on precision engineering and quality materials, as evidenced by the use of 7075 aluminium and six ball bearings in this assembly. Each component is laser-etched with the RC Overhaul logo, demonstrating attention to detail and quality standards throughout the manufacturing process.
