The Kawasaki W series is a line of vertical-twin standard motorcycles motorcycles made by Kawasaki beginning in 1965. First sold as a 1966 model in the North American market, the initial Kawasaki W1 had the largest engine displacement of any model manufactured in Japan at the time.[5][7][8]

Based heavily on a licensed version of the post-war, pre-unit construction, 500cc vertical-twin BSA A7, the bikes were clearly aimed at the market then dominated by the classic British twins of the day. Production of the original series, which saw W2 and W3 models, ended in 1974. In 1999 the W650 appeared, and was produced through 2007. In 2011 Kawasaki announced another retro version of the “W” brand, the W800, which remained in production until 2016,[9][10][11] then was re-introduced in 2019. A W175 was released in 2017.
