I rode the Tracer 700 and the NC750X before riding the 2017 650 Vstrom.
Great choice of bike. Comfy non slip seat, enough power for my liking, high seat as I'm 6'3", nice riding position.
Added the belly pan, hand guards and Givi V47 top box. Will add heated grips and extra lights later.
Average mpg of about 66 covering the commute, motorway and general relaxed riding.
First service just done £100 or so, next one is 4000 miles away.
My advice, go for it.
Regards
Graeme
