Description
The RK 219 primary chain is a replacement chain for DirtyBike Industries 219 primary chain drive kits on the SurRon Light Bee X and E-Ride Pro. All 219 replacement chains are endless, with no master link, for maximum strength and smooth running.
Why choose an RK 219 primary chain?
If you have already converted your primary drive to a DirtyBike 219 chain kit, the chain is the main wear part. Over time any chain will stretch and wear, which affects how smoothly power is delivered and can accelerate sprocket wear. A fresh RK 219 primary chain restores quiet, smooth running and keeps your conversion kit performing at its best.
- Replacement chain for DirtyBike Industries 219 primary drive kits
- RK sealed O-ring construction
- Endless design with no master link
- Suits SurRon Light Bee X and E-Ride Pro conversions
- Restores smooth, quiet primary drive
Why endless?
An endless chain has no master link, which removes a potential weak point. It also runs smoothly and quietly, which suits the primary drive position where the chain spins fast. The trade-off is that fitting an endless chain usually requires more dismantling than a chain with a master link – plan your job accordingly.
Signs your chain needs replacing
- Visible stretch or tight spots when rotating the drive
- Increased noise from the primary drive
- Rust or dry, stiff links that do not free up after lubrication
- Worn or hooked sprocket teeth
Chain care basics
A clean, lubricated chain lasts far longer. After dusty or muddy rides, clean the chain with a suitable cleaner and a soft brush, dry it, then apply a lubricant designed for sealed O-ring or X-ring chains. Check tension every few rides – a chain that is too tight wears sprockets and bearings, while one that is too loose can slap, wear quickly or come off.
Fitting tips
- Disconnect the battery and support the bike securely
- Follow the DirtyBike kit instructions for removing and refitting the primary drive components
- Inspect the sprockets and replace them if they are worn
- Set tension correctly and rotate the drive by hand before riding
