you certainly may ask yourself now ..why the hell does he look for 250`s if he`s got a full bike lisence ...
answer: because there are now so many speed limits in europe and even mores speed traps around , fuel is getting more and more expenciv so a 250 realy makes sence they all get you to 80mph and they return around 90-120mpg
best i had out of mine was 116mpg and as i`ve been on a 3500 miles trip around europe (belgium, germany,swizerland ,italy, france )i proved you can tour with them even on long distances and 600miles a day are not impossibel on a 250 , ok on high speed runs (85-90mph on motorways in germany) you need loads of fuel , had to fill up after only 250miles (still about 3 liter reseve left) 14 liter- 250 miles isnt realy bad (around 80mpg ) but thats what you need if you want to travel , in france/italy i found somtimes loads of the fuel stations are closed around lunchtime or even totally closed on sundays or during the week on one day most monday or wednesday ,sometimes you cant find one for 30 odd miles so its quit handy to have a reserve range of around 50-70 miles ok i didnt use main roads because i want to see more then motorway services in my holllidays
