The SH300i, first launched in 2007, was the big-wheel commuter at the top of Honda's SH scooter family. The 2011 update gave it new bodywork, new wheels, a better seat and revised frame, suspension and chassis settings for sharper handling. Its 279 cc fuel-injected single gave brisk performance with a V-Matic automatic drive, combined disc brakes (ABS optional) and underseat storage. It was later updated for Euro 4 and smart-key operation before the SH350i took over in 2021.
