Re: [St] Chain & Sprockets

["Peter Chittum" <motopeter@xxxxxxxxx>]

I really like the 18T front configuration. For me, my mileage actually went
up. Optimal engine speed for comfortable cruising takes you to a lower total
MPH, which no matter how you cut it will net you better fuel economy. I
still gun it on starts, but the way I ride when cruising has changed because
of the gearing.

But then, I'm mostly a commuter on highways, and don't get a lot of back
road flogging of my ST. I did the measurement for a while.

Before, with 19T configuration, typical MPG: 42-43
Now, with 18T configuration, typical MPG: 45-48.

It goes to show the biggest impact on economy isn't what gearing you ride,
but how you ride it. (At least in my case)
