Somewhere around 8-9000 miles per year, most of which is between March & November thanks to frequent trips to Snetterton, Brands Hatch & Silverstone, plus occasional visits to Nowrwich & Cambridge for gigs.
I put around £50 of fuel in the tank at the end of November and zeroed the trip meter, just before a 140 mile round trip to Cambridge and, as of yesterday, the trip meter reading is just under 250 miles and there's still 1/2 a tank of fuel left. In the first week of January alone, I did almost as many miles as that by bike!
