LOSI Promoto-MX Rear Brake Caliper (Aluminum Upgrade) JR-LMX06-RD by Jazrider  [JR-LMX06-RD]

Brake Caliper Details for Promoto-MX

This red anodized aluminum rear caliper is an RC-scale replacement intended for LOSI Promoto-MX motorcycle models. It is supplied by JAZRIDER with the designation JR-LMX06-RD and functions as a direct spare for Promoto-MX rear braking assemblies.

The design emphasises serviceability and stable braking feel: a stiff aluminum mount supports pads and linkages while the anodized finish helps minimise visible wear from handling and abrasive dirt exposure.

Installation and tuning notes: designed for the original Promoto-MX rear mount and brake linkage arrangement, the caliper typically installs with stock hardware. After installation, fine-tune pad alignment and lever travel to dial in braking sensitivity for your riding style.

Use cases: intended as a replacement for damaged OEM units, a maintenance spare, or an upgrade to retain consistent braking response after chassis changes on dirt tracks.
