The Heavy Hitter 520 Primary Chain Conversion is built for maximum performance and long-term durability, specifically designed for the Surron Ultra Bee. This upgrade is ideal for high-power setups and ensures reliable performance over time.

Unlike typical 420 sprockets that require more frequent maintenance and have a shorter lifespan, our conversion features a stronger 520 chain for enhanced durability. With heavier bikes like the Light Bee experiencing chain breaks under increased power and weight, this upgrade is a must.

We’ve also developed an exclusive dished rear sprocket to prevent damage to your frame caused by traditional flat sprockets. Our design maximizes clearance, ensuring your chain tension stays in spec and protects your bike from unnecessary wear.

Key Features

  • Exclusive dished sprocket for optimal clearance
  • 520 O-ring chain included for lasting durability
  • 7075 aluminum construction to prevent corrosion
  • Simple installation with no shims or spacers required (OEM motors only)
  • Master link chain for easy maintenance

Important Installation Note
Ensure that your chain tension is loose during installation to prevent issues. This kit is designed for OEM motors only. Aftermarket motors typically have a +4mm offset, and we are working on an update for compatibility.

Sur Ron Ultra Bee (OEM Motor Only)

Important Installation Notice
When installing the chain drive, ensure that the chain tension is loose. Tight chain tension can lead to issues during use.

This product is compatible with the OEM motor of the Sur Ron Ultra Bee. However, please note that factory variations, dealer-installed options, and aftermarket modifications may affect compatibility in certain cases. We recommend double-checking the compatibility of your bike setup before making a purchase to avoid any issues.

Absolutely love my Light Bee, I’m 6-1 200 and it hauls me around no problem, can hit full size Mx jumps or rip up single track like nobody’s business.

Bikes came in a nice secure crate and around the same time the seller anticipated. Seller is very quick to respond and polite/helpful. Easy to set up and ride out of the box! I will definitely purchase from this seller again.
