PROMOTO-MX 32T Hub Sprocket and 68 Roller Chain - MX6832S Replacement by GPM  [MX6832S]

32T Hub Sprocket plus 68 Roller Chain for PROMOTO-MX

This aftermarket drivetrain kit is intended for LOSI PROMOTO-MX motorcycles and is listed as model MX6832S. It combines a 32T medium carbon steel hub sprocket with a manganese steel 68 roller chain to provide a tough, serviceable replacement for worn final drive items on 1/4 scale dirt bike RTRs.

The parts suit the typical spur-and-chain configuration used on the PROMOTO-MX platform. Install the hub sprocket in the hub position and route the 68 chain over the sprocket and counter gear while confirming alignment and chain run. Usual setup steps include setting correct chain tension and checking each tooth engagement; use proper RC tooling and retainers for secure mounting.

Maintenance guidance: inspect after a few runs for wear, keep the chain lightly lubricated with an RC-compatible product, and verify fastener torque on a regular schedule. This kit is offered as a like-for-like replacement and tuning option, not as a performance guarantee.

Install the GPM MX6832S kit when replacing worn sprockets or altering final drive on PROMOTO-MX rigs, and confirm compatibility with the listed models before fitting.
