I have an 07 RSVR with akro's on and switched to map 2.
On a sunday blast with the boys, on fast a and b roads, i have had the light start showing as low as 90 miles.
Generally though it is 110-115 miles before the light comes on.
On a motorway/dual carriageway i've gone as long as 135 miles before the light comes on. Either way whenever the light comes on i stop and fill up as soon as i see a station. The bike will only take 13 litres to the neck. So i still had 4 litres left. I reckon i would get 40 miles out of her with the light on. So theoretically i could get between 170 and 180 miles out of her when cruising at 80mph on a motorway. Not bad for a big v twin sportsbike.
