What you see here is the very unassuming 2017 Yamaha YZF-R15, a 155cc single-cylinder sport bike that was designed with the Asian market in mind – as such, the bike will debut in Indonesia in April 2017, and the rest of the ASEAN market later this year.

Hold on before you click through though, as while the R15 might be too small by our Western market standards, the new Yamaha YZF-R15 packs some interesting technology, namely Yamaha’s variable valve actuation (VVA).

Because of this technology, Yamaha says that the 2017 model of the YZF-R15 achieves a 18% increase in power output (19hp in total), and a 4.7% increase in fuel efficiency, all from its 3% engine displacement increase and with the VVA technology.
