Overview
Transform your Losi Promoto-MX RC motorcycle with the Aluminum Chain Tension Adjuster Set, a premium upgrade that replaces the stock injection-moulded tension adjusters with precision-engineered aluminium components. Whether you're a serious RC enthusiast in the UK looking to enhance your 1/4 scale motorcycle or simply want to upgrade your Promoto-MX with parts that deliver both performance and aesthetics, this direct-fit accessory offers an immediate improvement to your RC experience. The Losi Aluminum Chain Tension Adjuster Set is designed specifically for riders who demand precision, durability and a professional appearance from their RC motorcycle setup.
Chain tension is critical to the performance and longevity of any RC motorcycle, and getting it right requires adjustments that are both precise and repeatable. Stock plastic adjusters can wear, flex and make fine-tuning difficult, but these premium aluminium replacements solve those problems entirely. By upgrading to the Losi Aluminum Chain Tension Adjuster Set, you gain the ability to make confident, accurate adjustments that will keep your chain at the optimal tension for maximum performance and chain life. This is a must-have upgrade for any serious Promoto-MX owner in the UK RC community.
Installation is straightforward—no additional parts are required. Simply remove the original tension adjusters from your Promoto-MX rear swing arm and install these aluminium upgrades in their place. Within minutes, your RC motorcycle will not only perform better but look significantly sharper on the track or bash course. These components are laser-etched with chain tension values, eliminating guesswork and allowing you to make precise adjustments every single time.
Key Features
- Precision CNC Machined from 6061-T6 Aluminium — Every component is machined to exact tolerances using precision CNC equipment, ensuring perfect fit and absolute consistency across the adjustment range. This manufacturing process guarantees that each adjuster works identically and delivers the repeatability serious RC riders demand.
- Clear Anodised Finish for Increased Durability — The clear anodised coating provides a protective layer that resists corrosion, oxidation and wear from regular use. This treatment ensures your adjusters will maintain their appearance and functionality through countless hours of riding, whether you are running on a track, bashing in grass or pushing through mud.
- Laser-Etched Chain Tension Values for Easy Identification — Each adjuster features laser-etched markings that indicate chain tension settings, taking the guesswork out of adjustments. These permanent etchings will never wear off or fade, allowing you to reference the correct tension settings quickly and accurately every time you need to fine-tune your Promoto-MX.
- Direct Fit Option Part for Promoto-MX with No Additional Parts Required — These adjusters are engineered as a perfect drop-in replacement for the stock plastic versions on your Losi Promoto-MX. No additional hardware, spacers or modifications are needed—simply install and go. This hassle-free installation means you can upgrade your motorcycle in minutes.
- Premium Aesthetics That Transform Your RC Motorcycle's Appearance — Beyond performance, the gleaming aluminium construction with clear anodising gives your Promoto-MX a professional, upgraded look that immediately sets it apart from stock setups. These components are visible on your rear swing arm, and they make a statement about your commitment to quality and precision.
Technical Performance
The Losi Aluminum Chain Tension Adjuster Set represents a significant engineering upgrade over standard plastic components. Manufactured from aerospace-grade 6061-T6 aluminium, these adjusters combine lightweight construction with exceptional strength and rigidity. The precision CNC machining process ensures tolerances that plastic injection-moulding simply cannot match, resulting in adjusters that maintain their position under load and do not flex or shift during aggressive riding. The clear anodised finish adds a protective oxide layer that resists the elements, corrosion and everyday wear, ensuring your investment will remain functional and attractive for years to come. For UK RC riders using their Promoto-MX in varying conditions—from indoor tracks to outdoor terrain—this durability is invaluable. The laser-etched tension values are permanent and cannot fade, weathered or rub off like printed markings, giving you reliable reference points for tension adjustment every single session. The engineering philosophy behind these adjusters is straightforward: provide the precision, durability and aesthetics that the modern RC motorcyclist demands, with zero compromise on fit or function.

Frequently Asked Questions
- Will the Losi Aluminum Chain Tension Adjuster Set fit my Promoto-MX motorcycle? — Yes, this is a direct fit part for the Losi Promoto-MX. It is engineered specifically to replace the stock injection-moulded tension adjusters on the rear swing arm. Whether you own the Promoto-MX FXR, Promoto-MX Pro Circuit or Promoto-MX Club MX, these adjusters will fit perfectly without requiring any additional parts or modifications.
- Is this adjuster set suitable for beginners? — Absolutely. While these adjusters are a performance upgrade, they are not complicated to install or use. If you can remove two plastic parts and bolt on two aluminium parts, you can complete this upgrade. The laser-etched tension values actually make the adjustment process easier for beginners by removing guesswork and providing clear reference points.
- What is the difference between these aluminium adjusters and the stock plastic ones? — The key differences are durability, precision and appearance. Stock adjusters are injection-moulded plastic that can flex, wear and develop play over time. These CNC-machined 6061-T6 aluminium adjusters are rigid, precise and will not degrade. Additionally, the laser-etched markings are permanent, whereas plastic versions may have printed markings that fade. The clear anodised finish also provides superior corrosion resistance compared to bare plastic.
- Do I need any special tools or additional parts to install these adjusters? — No. These are designed as a direct fit replacement with no other parts required. You will need only basic tools to remove the original adjusters and install the aluminium upgrade. The installation takes just a few minutes.
- Why are laser-etched markings better than printed ones? — Laser etching creates a permanent marking that is engraved into the aluminium itself, so it cannot fade, wear off or wash away. Printed markings on plastic adjusters can become illegible with use and exposure to UV light, dirt and moisture. The laser-etched system ensures you can always read your tension reference values clearly.
