2020 Yamaha SMAX [Model Overview]

2020 Yamaha SMAX

2020 Yamaha SMAX

Much like its big brother the XMAX, the 2020 Yamaha SMAX is a scooter that is poised on the premium end of things, yet won’t break your bank account. Powered by a 155cc, liquid-cooled, fuel-injected single, the SMAX boasts a chunky 15 crank HP. Unlike the XMAX, however, the SMAX is not a full-on maxi-scooter and is intended for usage almost entirely in-city.

One of the nicer things about the SMAX is that it is light enough to have both side stands and a center stand, yet it is heavy enough that at regular traffic speed, it is sure-footed and comfortable. It also has an extremely easy to read three-segment dash, and is fully automatic, just twist the wrist and off you go.

The 2020 Yamaha SMAX starts at $3,799 US/$4,099 CA
