Just finished the first tank of fuel on the Bandit

and it did 160 miles before the fuel warning light started to flash...

Compare that to the SV which managed approx 90 miles before warning...

OK 3L bigger tank, but even so my rought mental calculations tell me that it's a 30% improvement in MPG's.
The important thing from my point of view, however, is only having to fill up every 3 weeks instead of every 1.75 weeks when commuting.
