Unleash Raw Acceleration & Maximize Your Range
Prioritize lightning-fast throttle snap and zero drivetrain drag with the DXE RS Race Spec 420 Chain. Engineered specifically to handle the brutal, instant torque of high-performance electric motorcycles (including Sur-Ron, Talaria, and E Ride Pro), this non-O-ring race chain eliminates friction so you can transfer every watt of power directly to the ground.
By removing heavy rubber seals, your rear wheel spins completely free, yielding crisp throttle response and a noticeable boost in battery efficiency.
Key Features
-
Zero Mechanical Drag: The non-O-ring design completely eliminates the rolling resistance caused by rubber seals. Experience immediate throttle response and a freer-spinning drivetrain.
-
Maximum Battery Efficiency: Less friction means your motor doesn't have to work as hard. Expect up to a 5% to 10% increase in battery range compared to standard O-ring chains.
-
Slim Profile Sizing: Without bulky rubber rings, this chain features a narrower profile. It easily clears beefy aftermarket dirt tires without nasty sidewall rub.
-
Built for E-Moto Torque: Constructed with shot-peened steel plates and solid rollers to handle aggressive launches, track racing, and street shredding.

Length Sizing Guide
Choosing the right link count depends heavily on your rear sprocket setup:
-
106 Links: Ideal for stock sprocket configurations.
-
112 Links: Great for mild sprocket upgrades (e.g., 54T).
-
116 Links: Perfect for mid-to-large sprockets (e.g., 58T to 60T setups).
-
120 Links: Maximum length for monster torque sprockets (e.g., 64T setups) or extended swingarms; easily cut down to custom lengths.
Pro-Tip for E-Moto Riders: Because non-O-ring chains have metal-on-metal links, they require regular cleaning and lubrication after muddy or wet rides to prevent stretch and wear. Keep it lubed, and it will reward you with unparalleled snap and mileage!
