PROMOTO-MX Drive Sprocket 32T with 68 Roller Chain - MX6832S by GPM  [MX6832S]

32T Drive Sprocket and 68 Roller Chain Replacement

This aftermarket drivetrain kit is intended for LOSI PROMOTO-MX motorcycles and carries the model number MX6832S. It combines a 32T medium carbon steel hub sprocket with a 68 roller chain in manganese steel to deliver a resilient, serviceable replacement for worn final drive parts on 1/4 scale dirt bike RTRs.

The components suit the standard spur-and-chain layout used by the PROMOTO-MX platform. Fit the hub sprocket at the existing hub location and guide the 68 chain over the sprocket and counter gear, checking alignment and chain run. Common setup tasks include adjusting chain tension and confirming each tooth engagement; always use correct RC tools and keep fixings secure.

Service tips: inspect the chain and sprocket after initial runs, apply light chain lubricant designed for RC use, and recheck fastener torque periodically. The kit is supplied as a direct replacement and a tuning choice, not a claim of increased performance.

Fit the GPM MX6832S kit when replacing worn drivetrain pieces or altering final drive on PROMOTO-MX machines, and check compatibility with the models listed prior to installation.
