[QUOTE="Champ"] No, I *am* interested in absolute fuel consumption. I really think that a motorcycle that regularly does much less than 40mpg is poorly engineered.[/QUOTE] Couldn't agree more. The Gixxer returned nearly 50 at normal road speeds (1). My SOBeemer does 40 on a good day and nearer 30 on the M-Way. It's telling that the standard B12's manage little over 100 miles on a tank. This tuned engine makes 150 miles at conventional velocities. If HMG actually cared about emissions rather than tax take they would legislate minimum MPG for bikes/cars/vans related to engine capacity. I am pretty sure manufacturers could do a lot better. Co-incidentally I've been looking at the Hydrogen Cycle from a future investment POV. It's not all encouraging, although the driveline technology is fine the low energy content by volume, even in the liquified state, isn't encouraging. Unlikely to power passenger aircraft as a result and only useful in the Urban cycle for cars. Not easily applicable to motorcycles. Biofuels rule perhaps. (1) or around 17 on the track
