LOSI Promoto-MX Seat Support Upgrade JR-LMX01-GR by Jazrider  [JR-LMX01-GR]

Aftermarket aluminum seat support for Promoto-MX

This JR-LMX01-GR machined aluminum front faucet seat support is an aftermarket replacement compatible with Team Losi Promoto-MX motorcycle models. It functions as a concentrated crash structure and stiffens the seat mount to provide a reliable forward mounting point that helps absorb impact loads and protect nearby plastic parts.

Design intent: emphasis is placed on structural reinforcement and crash load distribution, not on suspension or steering. The green anodized finish denotes the JR-LMX01-GR variant and aids quick visual checks during setup and maintenance.

Installation notes: remove the stock front seat or upper frame fasteners, align the JR-LMX01-GR with the Promoto-MX chassis mounting bosses, and where directed reuse the original screws according to your service manual. Confirm thread engagement, apply torque carefully to prevent stripping, and ensure no interference with bodywork before final assembly.

Tuning notes: installing this aluminum support increases local stiffness at the front seat area with only modest effects on overall chassis feel during heavy landings; use it when a firmer seat anchor or a replacement for a damaged plastic support is required.

JR-LMX01-GR is a direct-fit aluminum support for Promoto-MX where additional front-seat rigidity or a replacement crash structure is necessary; follow normal RC maintenance practice for fitting and checks.
