My 650 Triumph would do 100 imperial mpg with an HS2 SU. But it wasn't a T'Bird, with a 9 stud top end, 9:1 pistons and Bonnie cams....and it wasn't a Triumph either, but a Triton and weighed a lot less than a stock bike. Still, how come my 650 Triumph could do 100mpg, and my 600cc Norton also with an HS2 could do over 90mpg....and yet my 650 BMW of similar hp can't get anywhere near those figures ?
