The all-new SH350i packs a displacement punch beyond the outgoing SH300i model. It boasts Honda’s 350cc eSP+ engine—and if you’re not familiar, there’s nothing psychic about it. OEMs love their acronyms, and Honda is no different. 

The eSP designation stands for “Enhanced Smart Power,” which combines several Honda technologies to make for a more seamless, flowing rider experience. The most immediately noticeable ones for riders include the Honda ACG starter, which avoids any startup jolts or gear-meshing noises. It also allows the Idling Stop System to function—helping you reduce emissions and also save on fuel consumption. 


Another part is Honda’s programmed fuel injection (PGM-FI), which is Team Red’s proprietary digital system that’s been in use since the early ‘80s. Deeper down, eSP also makes use of Honda engine design qualities that reduce friction in moving parts, and also improve combustion inside a more compact chamber. 

The SH350i gets some other 2021 Honda upgrades, including updated styling, a new LCD display, emergency stop signals, a USB charging port, Honda Smart Key, and Honda Selectable Torque Control.
