SH350i (NF11)
The Big-Wheel City Workhorse
The Machine's Character
The SH350i is Honda's answer to a simple question: how much scooter do you really need to cover the city and the freeway with one machine? The answer is a 330 cc liquid-cooled single with 29 hp and 23 lb-ft, hung in an underbone frame with belt final drive. ABS and traction control are standard, and so are keyless ignition, a USB charging port and an LED headlight. Nothing here is built to impress on a spec sheet. It's built to make your weekday shorter, and that's exactly why it sits at the premium end of the step-through class. Typical Honda!
On the road it puts smooth power delivery and stability ahead of aggression, and that's the right call for a machine that lives between traffic lights and on-ramps. It's easy to handle and cheap to run at 71 mpg, with carrying capacity to match. It's for you if you want a daily tool that also holds its own on fast freeways. The honest caveat is the electrical side: keyless ignition loads the battery hard, and cold-start idle hunting and stalling are known issues on this generation. Keep a charger handy.
