New for 2019 across all Yamaha equipped models is the introduction of Yamaha PW-SE motors – with improved response to higher cadence and a higher torque output.

Across HardSeven, FullSeven and even Cross & Trekking models we’ve introduced intube batteries, not only for a sleeker look, but so that Yamaha models can benefit from our Modular Rail System line of accessories. Our Bosch equipped Trekking and Cross models have been improved too making them more accessible with rider focussed Bosch Active plus systems.
