Mitsuboshi Belts (MBL)

Yamaha 8DN drive belts have gained a reputation as being a durable piece, as evidenced by the turbo and supercharged RX-1s that produce HP in the hundreds, all being transferred through the drive system by a stock Yamaha drive belt, manufactured by MBL, or Mitsuboshi. Notice the “O” in the name. This is not the same as Mitsubishi, the car and electronics manufacturer. Often, the drive belts are referred to as Mitsubishi; this is not correct.
