So following from a trip I did in the first week of owning my Tracer, where I did 202 miles before I bottled it and filled up, today as I was doing almost the same route, I decided to do it again!
After the fuel light started flashing I did a simple 15 miles on top.
In this instance I'd managed 194 miles on a tank, ave speed was 75mph on motorways. In standard mode all the way with a fully laden bike + 20kg or more in the bags.
Put in (bike on centre stand) 16.23 litres at the pump! So had more than enough for twice that mileage on "empty".
Over a 400 mile round trip I managed an ave of 54mpg. Not bad I'd say, partially as the ave speed on the return leg was more 85mph.
