The SR400 was previously available only in Japan, but Yamaha has decided to bring it stateside for 2015 due to the popularity of standard-styled motorcycles to newbies and the hipster demographic.The SR400’s older brother, the SR500, was available in North America from 1978-1999, but that was the last time Yamaha offered an SR in the US.The 2015 SR400 arrives with simple 399cc single-cylinder engine with fuel injection, and a friendly 384-lb. wet weight. The styling is completely retro, and so is some function, such as the kick start (no electric starting). But like other SR models, the SR400 features a compression-release valve for easy turnover.Attached above is 2015 Yamaha SR400 photo gallery. Each image also makes great wallpaper.
