My scrambler was doing 44 mpg on its first run out from new which increased to 54 mpg and today it went to 61mpg on occasion but was mostly around 58 mpg , I am still running the bike and I am upto 378 miles, it’s not been a bad bike to run in as at 4000 rpm it will do 70-75 and now I can go upto 5000 rpm which is quick enough on the shitty wet muddy roads in Yorkshire England.
