2012 Suzuki V-Strom 650 ABS First Ride | Rider Magazine
It's hard to believe the mileage claims. I never get mileage that low on my existing V-Strom except at high altitude with crappy fuel and high speeds. So sure I could believe that a 90mph range is lower, but I don't care if the 60mph range is the same and if around town or dirt track mileage is higher.
I reliably got ~20km/l on my K6, maybe 22 on a long haul at legal speeds. Absolute best ~23 on cold night rides when speeds were well down.
My 2012 - still running in, is getting at least 23km/l - that's from the display on the dash. Calculating based on refill/distance instead it's getting more like 24.5km/l.
My K6 during breakin got around 18km/l.
Basically, I'm getting > 15% better milage over a K6 and it may well improve after the first service.
Surprisingly, it's doing proportionately better in comuting conditions where I'd expect the time spent idling to eat a lot of the difference. High error margin, but my only 'mostly commute' run so far I put 6.11 l in for 168km. (Remember +/- 0.5 l error here in how much fuel I jammed in).
Power - it's improved, hard to tell by how much since it's waiting for it's first service, but I'd be prepared to believe something like the +10HP the Gladius engine should deliver - it's a lot better handling and faster accelerating for sure, even short shifting to keep the rpm's down during breakin it's noticeably faster than the K6.
It's not DL 1000 power, but at near legal speeds I suspect the on road performance difference would be pretty minimal now.
I'd guess the magazine figures are poor because they are really caning the bikes , the superb handling certainly invites that.
Cheers
