The 420 X-Ring chain 112L is a motorcycle-grade secondary drive chain built for Sur-Ron, Talaria, E Ride Pro and 79 Bike electric dirt bikes. It also fits any other machine running 420 standard gearing. The pitch is 420, the length is 112 links, and the sealing profile is X-Ring.
This chain works in the secondary drive. In other words, it runs between the jackshaft and the rear sprocket. It matches 420 profile sprockets, for example a 14T front paired with a 48-60T rear. Therefore it replaces the original chain without adapters or modifications.
X-Ring sealing uses X-shaped rings with four contact edges. As a result, friction stays lower than with O-Ring seals, and the factory grease remains between the pin and the bushing for longer. The practical outcome is quieter running and slower stretch over time.
Key Benefits
- X-Ring sealing – four sealing edges trap lubricant inside each link far better than an O-Ring profile.
- Quieter operation – reduced friction cuts drivetrain noise and chain slap on rough ground.
- Longer service life – lower friction means slower stretch and slower wear across the whole drivetrain.
- Smoother delivery – power transfer stays more even, so vibration through the frame drops.
- 112 link length – matches most OEM configurations, so fitting usually needs no shortening.
- 420 standard – the same 1/2″ pitch used on pit bikes and small-capacity dirt bikes.
- Less maintenance – tension adjustment and lubrication are needed less often.
- Better efficiency – lower friction losses keep drive delivery more consistent.
Who Is This Chain For?
This chain suits Sur-Ron riders, including Light Bee and Light Bee X models. It also covers the Talaria range, such as Sting, Sting R and the MX series. Owners of E Ride Pro and 79 Bike machines are equally covered.
Beyond those models, the chain fits any other vehicle whose drivetrain uses the 420 standard. It installs in the secondary drive only. Specifically, it links the jackshaft to the rear sprocket. Before ordering, confirm that you need the secondary chain rather than the primary one.
The chain works well for daily commuters, off-road riders and anyone who has already moved to a larger rear sprocket. Furthermore, a drive chain is a standard wear item. Replace it together with worn sprockets for the best result.

Why Choose the 420 X-Ring Chain 112L?
The main difference from cheaper options is the X-Ring profile rather than an O-Ring one. Four sealing edges instead of two reduce rolling friction. They also hold lubricant more effectively inside the link. Consequently, the same chain runs quieter and lasts longer on the bike.
The 112 link length covers most stock Sur-Ron and Talaria configurations. However, riders running a high-tooth rear sprocket or a tensioner may need fewer links. Surplus links come off easily with a chain breaker and riveting tool.
On the trail the benefits are easy to feel. There is less chain slap, more consistent drive and fewer tension adjustments between rides. In addition, lower friction means fewer energy losses through the drivetrain.
Frequently Asked Questions
Will this chain fit my Sur-Ron Light Bee?
- Yes. The 112 link length matches most stock Sur-Ron Light Bee and Light Bee X setups.
- It mounts in the secondary drive, between the jackshaft and the rear sprocket.
Does it work on a Talaria Sting or MX?
- Yes. Talaria Sting, Sting R and MX series bikes all use the 420 standard.
- E Ride Pro and 79 Bike machines are covered as well.
What is the difference between X-Ring and O-Ring?
- An X-Ring seal has four contact edges, while an O-Ring has two.
- Lower friction results, so lubricant stays sealed inside the link longer.
- The chain therefore runs quieter and stretches more slowly.
Which sprockets can I run with it?
- Any 420 profile sprocket set is suitable.
- A typical combination is a 14T front with a 48-60T rear.
Do I need to shorten the chain?
- Usually not, because 112 links matches many OEM configurations.
- Compare the 112L length against your current setup first.
- If it is too long, remove links with a chain breaker.
Is this the primary or the secondary chain?
- This is the secondary drive chain only.
- It connects the jackshaft to the rear sprocket, not the motor to the jackshaft.
Is a connecting link supplied?
- A connecting link may be included, depending on the batch specification.
How should I break in a new chain?
- Set the correct chain tension and align the drive line first.
- Ride gently for roughly 20-50 km during the break-in period.
- Check front and rear sprocket condition, since worn sprockets accelerate chain wear.
A sealed 420 chain is one of the simplest upgrades on an electric dirt bike. With four sealing edges, 112 links and full 420 compatibility, this chain slots straight into Sur-Ron, Talaria, E Ride Pro and 79 Bike drivetrains. Fit it alongside fresh sprockets and keep the tension checked for the longest service life.
