Product Information
Full details
The Renthal MX R1 drive chain is designed for serious off-road riders who demand reliable, consistent power transfer in high-impact environments. Featuring a 428 pitch and 122 links, this non-sealed chain is engineered for agility and smooth drivetrain engagement, making it an excellent choice for competition bikes; however, because it lacks X-rings, it requires more frequent lubrication and maintenance than sealed-ring alternatives.

FAQs
Can I use this chain for adventure touring or street riding?
While it will fit, this chain is specifically designed for off-road/motocross. The lack of seals makes it unsuitable for long-distance street use as it will require near-constant lubrication.
Does this chain come with a master link?
Yes, the Renthal MX R1 includes a master link to facilitate installation and removal without specialized heavy-duty tools.
How often should I clean the MX R1 chain?
Ideally, you should clean and lubricate it after every ride, especially if you have ridden in wet, sandy, or muddy conditions.
What is the benefit of the shot-peened plates?
Shot-peening creates a compressed layer on the surface of the metal, which significantly increases the fatigue strength and resistance to cracking under repeated heavy impact.
Can I shorten this chain if my bike needs fewer than 122 links?
Yes, you can use a high-quality chain breaker tool to remove excess links to reach your motorcycle's required length.
Troubleshooting
Chain appearing loose shortly after installation
New chains often experience a 'break-in' period where they stretch slightly. Re-adjust the tension using your bike's axle blocks to the manufacturer's specified slack.
Excessive rust on side plates
This indicates a lack of lubrication. Thoroughly clean the chain with a soft brush and chain cleaner, then apply a water-repellent chain lubricant.
Kinked or stiff links
If a link does not move freely, ensure it is properly cleaned and lubricated. If the link remains stiff after deep cleaning, the chain is likely damaged and should be replaced.
Pros and Cons
Pros
- High fatigue strength from shot-peened plates
- Reduced friction via chamfered inner links
- Excellent power transfer responsiveness
- Durable load distribution from extended bushings
Cons
- Requires more frequent cleaning and lubrication
- Lacks internal seals to trap lubricant
- Susceptible to rapid wear if not maintained regularly
Setup, Compatibility & Care
Proper installation is vital for the longevity of your drivetrain. Ensure you are matching the 428 pitch to the correct sprocket size on your motorcycle; mismatching pitch will cause catastrophic damage to both the chain and sprockets.
When installing, verify that the master link clip is oriented with the closed end facing the direction of chain travel to prevent it from being dislodged by external debris. For care, use a high-quality off-road chain lubricant immediately after washing the bike to prevent rust and internal wear. Regularly inspect the chain tension according to your motorcycle owner's manual, as a chain that is too tight will put excessive stress on the countershaft seal and the drive chain itself.
