I had the Aprilia's front sprocket changed out from the standard 17-tooth to 16-tooth AND get the suspension adjusted for my weight. Wow, what a difference the combination makes. The bike now rides much more pliant instead of bucking me off with the bumps or feel out of sort in the corners. The rear wasn't too bad from the factory setting but the front was way off for my weight. Being fat doesn't help much. The 17-tooth standard sprocket makes for great cruising, but too high for low speed handling and tight cornering. The bike stuttered and lugged in one gear and revs too high if I were to downshift. Now, it's spot on. Now, the power delivery is smoother and I get a bit more engine braking back too. The drawbacks are that there is more noticeable vibration at freeway speed and a loss of gas mileage. Since that the bike isn't a cruiser, I'm more than glad to make the trade off. And the Throttlemeister throttle friction lock will help with the numbed hand. I would suggest that if a bike has adjustable suspension, go get it adjusted. You don't have to corner hard or go like the devil in order to appreciate a well sorted suspension setup. Same thing with the gearing. It costed me $100 to get this done ($30 for the front sprocket and about an hour worth of work for installation of the sprocket and fooling around with the suspensions). The guy had me sitting on the bike with various positions, measuring the compressions and made various adjustments. Naturally, if you're mechanically inclined and have all the tools and bike stands, you can do it yourself. I also helped a fellow Beemer owner to set his rear shock and he noticed a big improvement as well. Alas, his front was a non-adjustable unit.
