RK 420 Green Chain 106L
The Problem Every Electric Motocross Rider Knows
The RK 420 green chain 106L is the professional-grade drivetrain upgrade for Sur-Ron Light Bee and Talaria Sting riders who demand performance and style.
The Solution: RK 420 Green Chain 106L
The RK 420 Green Chain (106L) combines proven RK durability with a striking green finish. RK chains are trusted by professional MX riders worldwide, the 420MXZ series is engineered specifically for high-stress motocross applications, with a surface treatment that resists corrosion and reduces friction.
Three Steps to a Better Drivetrain
- Order your RK 420 Green Chain from eMotoX Sports, in stock and ready to ship.
- Fit using a chain breaker and rivet tool, no specialist skills required.
- Apply chain lube, set correct tension, and ride.
What Happens If You Leave It Too Long
Ignoring a worn chain leads to skipping under hard acceleration, damaged sprocket teeth, and potential chain snap on the trail, turning a £22 replacement into a £120+ drivetrain rebuild.
Ride With Confidence
A fresh RK 420 Green Chain delivers crisp, direct power transfer with a custom look that sets your build apart from every other bike on the trail.

Will this fit my Sur-Ron Light Bee?
Yes, direct replacement for Sur-Ron Light Bee X and L1E with the standard 13T/48T sprocket setup.
Does this fit the Talaria Sting?
Yes, the Talaria Sting and Sting R use the same 420 pitch, 106L chain.
Is the green finish durable?
Yes, the RK 420MXZ green finish is a surface treatment applied during manufacturing, not a paint. It resists chipping and corrosion better than a painted finish.
How many links do I need?
106 links is correct for the standard 13T/48T sprocket combination on Sur-Ron Light Bee and Talaria Sting.
What lubricant should I use?
Use a dedicated MX chain lubricant such as XCP Chain Lube. Apply after every wet ride or every 3–4 dry rides.
Is a masterlink included?
The RK 420MXZ-106 is supplied with a clip link. For permanent fitment, use a rivet link.
How does RK compare to DID?
Both are premium chain brands trusted by professional MX riders. RK and DID are considered the top two chain manufacturers in the motocross world, both are excellent choices.
Can I use this on a Sur-Ron Ultra Bee?
No, the Ultra Bee uses a 520 pitch chain. This chain is for Light Bee and Talaria Sting models only.
How do I know when my chain needs replacing?
Replace when you see stiff links, visible rust, or when the chain lifts more than 12 mm off the rear sprocket at the midpoint.
Does the colour affect performance?
No, the colour is purely aesthetic. The green finish is a surface treatment that also provides corrosion resistance.
