Key Features
- Gold Anodised 7075-T6 Aluminium Construction — This sprocket is manufactured from premium grade 7075-T6 aluminium, one of the highest strength aluminium alloys available, which provides exceptional durability and resistance to wear whilst remaining lightweight for optimal performance. The gold anodised finish adds a protective oxide layer that resists corrosion and oxidation, ensuring your sprocket maintains its appearance and functionality even with regular use and exposure to outdoor conditions typical of UK RC racing and bashing.
- Direct Replacement Part — Engineered as a perfect direct replacement for the rear sprocket on both the Losi Promoto-MX and Promoto-SM motorcycle models, this component ensures seamless integration with your existing drivetrain without any modification or adjustment required, saving you time and frustration during installation.
- Premium Transmission Upgrade — As a transmission tune-up component, this sprocket is ideal for riders looking to refresh their drivetrain, improve drivetrain reliability, or simply replace a worn original component with a genuine Losi part that meets exact factory specifications.
- Genuine Losi Quality — As an official Losi component, this sprocket maintains the precision engineering and quality control standards that Losi applies to all its products, ensuring compatibility, durability, and performance with your RC motorcycle model.
Technical Performance
The LOS Hub Chain Sprocket represents the standard in precision transmission engineering for 1/4 scale RC motorcycles. Manufactured from 7075-T6 aluminium, this material is renowned in motorsport and aerospace applications for its exceptional strength-to-weight ratio and resistance to fatigue, making it ideal for the demands of RC racing and recreational riding. The gold anodised finish is applied through an electrochemical process that creates a hard, protective oxide layer on the aluminium surface, providing superior corrosion resistance compared to standard clear anodising. This is particularly beneficial for UK RC enthusiasts who operate their models in variable weather conditions and damp environments. The sprocket's design maintains exact gear tooth profiles and pitch specifications required for smooth, efficient power transmission through the chain drive system of the Promoto-MX and Promoto-SM models. The precision manufacturing ensures minimal backlash and maximum engagement with the chain, reducing drivetrain noise, vibration, and wear during operation. This component works in conjunction with your model's motor and ESC system to deliver reliable acceleration and speed characteristics, making it suitable for both recreational bashing and competitive racing applications.

- What makes the gold anodised finish better than standard sprockets? — The gold anodised 7075-T6 aluminium construction provides two distinct advantages: firstly, the premium 7075-T6 aluminium alloy offers superior strength and fatigue resistance compared to lower grade aluminium, ensuring the sprocket withstands the stresses of acceleration, deceleration, and gear engagement over extended use; secondly, the gold anodised finish creates a protective oxide layer that resists corrosion, oxidation, and wear, keeping your sprocket looking premium whilst maintaining optimal functionality in damp UK conditions and during outdoor RC racing and bashing sessions.
- Is this a genuine Losi component? — Yes, this is an authentic Losi spare part manufactured to original equipment manufacturer specifications. The part number Z-LOS362007 and EAN code 0605482170946 confirm this is a genuine Losi product, not an aftermarket alternative. Buying genuine parts ensures perfect compatibility, reliability, and longevity for your RC motorcycle.
- Do I need any special tools to install this sprocket? — Installation of the hub chain sprocket requires only standard RC model tools. Detailed installation instructions should accompany your Losi model, and our team at RC Model Shop can provide guidance if you need support with the replacement process.
- Will this improve my RC motorcycle's performance? — If you're replacing a worn or damaged sprocket, this genuine Losi replacement will restore your drivetrain to factory specifications and performance levels. The sprocket works as part of your complete transmission system, so its condition directly affects acceleration smoothness, reliability, and overall riding experience. Upgrading to this premium gold anodised sprocket ensures optimal performance and durability.
- Is this suitable for beginners? — This is a replacement transmission component designed for owners of existing Losi Promoto-MX or Promoto-SM ready to run RC motorcycles. It's not a complete model, but rather a spare part or upgrade component.
