The BCB Take
The SR/S takes everything that made the SR/F such a strong electric roadster and wraps it in a more practical package. The full fairing doesn't just change the styling, it improves rider comfort at motorway speeds and helps squeeze more range from the same Z-Force platform.
If the SR/F is aimed at riders chasing back-road thrills, the SR/S is built for covering miles. With premium suspension, fast charging and one of the most refined electric powertrains on the market, it remains one of the benchmark electric sports tourers available today.
Ride safe, folks.
