Kawasaki's 650R has been a popular choice in the mid-size sports bike arena ever since its arrival in 2006. The bike garnered instant success thanks to its practical nature and sportscar-rivaling performance. A year later, the Japanese brand launched the revamped 650R featuring a sleeker design, better ergonomics and improved quality. The revamped model retains the fuel-injected, 649cc parallel twin engine. Known for its linear torque delivery throughout the rev-range, this liquid-cooled four stroke unit puts out around 71bhp of power.
