Yeah, two totally different types of bikes. Both are nice in their own way. Funny thing, I recently had to replace the stock front tire which was worn after only 5K miles. The dealer didn't have a direct replacement 90/110, so I put a 90 / 100 on it (which is a slightly narrower tire). I figured it would look cool and wouldn't realy affect the handling. Well, I was wrong, the bike feels lighter and more flickable with the narrower tire. Took me a little while to get used to it, but overall not bad. So there may be a cheaper solution for you out there.
