About Piper Moto

John Piper founded PiperMoto in 2013 to design and build bikes.

His individual approach combines precision engineering with hand built artisan methods.

The inspiration for PiperMoto comes from an ambition to create extremely functional and desirable products. John’s background in motorsport gives him access to a network of top class manufacturers and materials.

Using modern design methods with a craftsman’s approach, he draws on his engineering integrity and attention to detail on every aspect of the machine.

j Series

The J SERIES is PiperMoto’s first project. John describes it as a Super Scooter; a hybrid of contemporary motorcycle engineering performance, with classic scooter looks and styling.

Built to order, each machine is finished to a personal detail specification, and carries the customers individual chassis number.
