The BD-207L from Yokomo serves as the replacement rear drive belt when a BD7-2015 touring car is converted to a forward motor layout. It routes torque from the front-mounted motor back to the rear drivetrain components.
This item is specified for BD7-2015 platform variants MRTC-BD715B, MRTC-BD715O, and MRTC-BD715S. Make sure your chassis code matches one of these listed variants prior to purchase and installation.
Installation guidance: follow the converted drivetrain pulley path when fitting, check that pulleys run in the same plane, and tension the belt to remove slack but avoid excessive preload. Recheck belt seating after a few brief runs to catch any misalignment early.
Tuning impact: belt condition and tension affect drive feel and efficiency. Proper alignment and tensioning will reduce drivetrain play and losses, whereas a fatigued belt can introduce inconsistency in power delivery. Regular checks and timely replacement maintain consistent handling.
