Photo shows a Kawasaki W650 outfit. Now, fast forward to 2011 - 2012 . . . . . now we have the version with a a capacity of 773cc . . . Review: 2011 Kawasaki W800 * poster's note: Poor speed conversion. 120 km/h converts to 74.56 Miles/hour (mph) All the appearance of classic air-cooled motors . . . . . some aspects are as they were in the past . . . .but there have been quite some changes. Kawasaki W800 (actual 773cc) 70 hp . . . . . . 60Nm torque - maximum torque available at 2500 rpm . . . . Now, for the Royal Enfield Bullet EFI . . . you have 499cc 27bhp Torque 41.3 Nm @4000 rpm Sort of a big gap between these two machines. I know which one will be hardly bothered by the addition of a sidecar.
