This machined 7075 aluminium chain guard is an RC-scale replacement engineered for LOSI PROMO-MX motorcycle platforms, offering a stiffer, service-oriented option versus standard plastic parts. The 7075 material and machined finish focus on protecting the chain and adjacent drivetrain components during routine operation and setup procedures.
Installation aligns with the original LOSI PROMO-MX mounting points and supplied fastener pattern, eliminating the need for chassis modification. The guard assists in maintaining consistent chain alignment under load, which supports repeatable drivetrain behaviour during tuning and validation runs.
