Primary Chain Kit 219 Sur-Ron Light Bee

Primary Chain Kit 219 for Sur-Ron Light Bee – Primary Drive Chain Kit (13T/30T)

Stronger and more efficient beltless primary drive. This 219 standard primary chain set replaces the belt and pulleys with a chain and two sprockets, while maintaining the original transmission ratio (13T/30T). The kit is designed for use in sand, mud and intense off-road conditions.

Why choose

• Much stronger than a belt – resistant to sand, dirt and shocks.
• Higher efficiency – lower contact area and friction coefficient than belt drives.
• Easier maintenance – replacing the chain is easier than replacing the belt, without removing the swingarm.
• The OEM ratio of 13T/30T combination maintains the original transmission geometry.
• Durable materials – hardened steel for sprockets, quality 219 chain.

What’s included

• 13T hardened steel motor sprocket.
• 30T reduction (primary) shaft sprocket.
• 219 chain (length according to OEM ratio).

Specifications

• Standard: #219 chain.
• Materials: hardened steel (sprockets), high-strength chain.
• Installation: bolt-on; no need to remove the swingarm to change the chain.

Benefits in real driving

• More stable power transmission on uneven ground and jumps.
• Lower losses – more efficient use of engine power.
• Faster maintenance – shorter stops at the workshop or garage.

Installation tips

• Check the sprocket line and chain tension after the first 20-50 km.
• Use a suitable lubricant for 219 chains; avoid aggressive solvents for seals.
