I finally got around to swapping the sprockets, so I wanted to revisit this and report the outcome.
I went with a 15t front and 37t rear, which puts it at around a 9.12% difference. The speedo reads at 101-102 kph when I'm actually going 100, which I'm liking as margin to prevent tickets. No longer running the numbers in my head frees up some mindspace, and I found that especially important last night when riding in an unfamiliar area in heavy traffic.
There is a definite reduction in acceleration, particularly in 2cd gear. The tradeoff is that 100 kph highways no longer make my hands numb, and 110 kph highways no longer feel like I'm sitting on a paint shaker. The increase in comfort over long distances is worth the loss of power IMO.
All in all, I'm happy with the change. I'm still out accelerating everything I care to, and since most of my riding is at 80+ kph reducing vibration makes my trips a lot more comfortable.
I keep a spreadsheet to track all my expenses, maintenance, etc, and I've modified it to account for the new sprockets so I know what the odo should read despite the sprocket change.
Every bike is a good bike. The question is whether or not it's the best bike for what you want to do.
The Little Sport Tourer That Could - 2011 CBR250R with touring windscreen, Saddlemen seat, tank cover, frame sliders, mirror extenders, taller gearing via sprockets to fix speedo and reduce vibration at highway speed.
