The Yokomo BD-207L is the rear drive belt used when a BD7-2015 touring car is converted to a front-mounted motor layout. It replaces the original belt and transmits power from the converted motor position to the rear gearbox.
Compatibility is limited to the BD7-2015 variants MRTC-BD715B, MRTC-BD715O, and MRTC-BD715S listed for this part. Double-check your chassis code before fitting to ensure correct fitment.
Installation notes: install the belt following the converted pulley route, confirm pulleys are parallel and aligned, and tension to remove slack without overloading bearings. Inspect belt seating and look for uneven wear after the initial run-in period.
Performance role: this belt links the motor to the rear geartrain and has a direct effect on drivetrain smoothness and responsiveness. Keeping correct belt tension and alignment minimizes slop and drivetrain losses; replace belts that show stretching or fraying to preserve consistent power delivery.
