Today, I would like to report "Mototwin Retro Racer Bonneville Pipes” for Bonneville. The swept-back type pipes used to be the popular exhaust system for those classical cafe racers such as Norton and Triton motorcycles found in those good old days.

The installing the swept-back pipes was a bit tricky, maybe due to product-to-product variability as it is manufactured by hand-made basis. The significant changes are the looks and exhaust sound. With these pipes, the new Bonneville looks like a cafe racer and it was indeed nice to just look and admire the entire figure. In addition, the exhaust sound is also different from the one with the factory pipes. The factory pipes are connected by an intermediate pipe just under the engine, while the swept-back pipes are separated. Because of this, the swept-back pipes produce very brisk and spirited parallel twin sound. The drawback is that, because of this separation, the torque power is compromised to some degrees. Although the swept-back pipes are not installed in my current Bonneville, I think it is worth trying for someone seeking for cafe-racer style Bonneville.
