420 Jackshaft Sprocket | By Warp 9 | For E-Ride Pro , Sur-Ron, 79Bike

Hardened Tool Steel Strength for 420 Chain Setups

If you are running a 420 chain conversion on your build, this Warp 9 420 Jackshaft Sprocket is the upgrade you want. Precision machined from hardened tool steel and finished with a black oxide coating, it is built to handle higher torque loads, aggressive riding, and long-term wear without premature failure.

We have seen stock sprockets wear quickly once power levels increase. This is a simple drivetrain upgrade that adds real durability and peace of mind.

Construction and Materials

• Hardened Tool Steel for maximum strength and wear resistance
• Black oxide coating for corrosion protection
• Designed specifically for 420 chain setups
• Precision machined for accurate fit and smooth drivetrain operation

Tooth Count Options

• 14 Tooth – Stock replacement size for 420 setups. Maintains factory-style torque and acceleration feel.
• 15 Tooth – Lowers RPM at cruising speed for smoother riding and potential top speed gains. Slight reduction in torque compared to 14T.

Important Fitment Note

This sprocket does NOT fit bikes running a 428 chain.

It is not compatible with E-Ride Pro SR or E-Ride Pro SS 3.0 models in their stock 428 chain configuration. Those bikes require a 428 specific sprocket unless converted to a full 420 chain system.

Fitment

• E-Ride Pro models with to 420 chain
• Sur-Ron Light Bee with 420 setup
• 79Bike models running 420 chain configuration

At REV Rides, we always recommend matching sprockets exactly to your chain pitch. Running the correct 420 sprocket with a 420 chain ensures proper engagement, smoother power delivery, and longer drivetrain life.

Best For

• Riders completing a 420 chain conversion
• High power builds looking for stronger drivetrain components
• Trail and track riders who want long-term durability
