I'm looking at mpg from more of a financial standpoint than a "saving the world" standpoint. With that in mind, I don't see a big deal with even increasing mpg by 10. Heres an equation for annual gas savings:

(annual miles) * (1/(other vehicle mpg) - 1/(cbr mpg)) * (average gas price)

For me, I'm looking at about 14,000 miles per year, the cbr gets minimum 66 mpg, my WRX gets 22 mpg, and gas is $2.75 a gallon in Colorado right now. If I figure $3 average over the year I get $1272 savings. If the cbr got 76 mpg it moves up to $1356.

Meh, not a big deal. The majority of my savings come from avoiding depreciation on my car and putting it on the $4000 cbr anyway. I'd rather beat the absolute piss out of the bike and not worry about $85 a year.

That said, if you ARE trying to save the world - hypermile away my friends. It's cool, just not something I want to do myself.

Riding "comfortably" works for me.

I got 77mpg before I installed a one tooth larger front sprocket. Now I love the way the bike commutes and cruises at lower rpm. And with 6 gears I can always down shift for acceleration and whenever I feel like driving it like a Ferrari. For me I would say that the gearing is now perfect, whereas I felt that the factory gearing was low so that beginners do not stall the bike. And then I installed a digital devise that corrects the speedometer. I need to get a reading now on mpg but I definitely feel that it is better than stock. I know that I don't have to put gas in very often.

@redfan, good for you! I also installed a 15t front sprocket recently ( from a 13t ) and agree with the improvement for my purposes( better freeway cruising and better fuel economy). The CBR pulls the taller gearing easily so I will be changing the rear to a 36t sprocket. I got 88 mpg with the 13t and I should be breaking 100 mpg pretty soon.
