I agree with a lot of people here, it's mostly for looks. I have owned 150's up to a 200 rear now and really not much of a difference but when I demo rode the Rocker I could really notice the difference with the 240. You had to push more to get it in the corners and it did want to stand back up. Anything above 200 and you will notice.

 

I find the bigger fronts tire you feel the tire weight on bumps. And the large rear tire will spin faster than thinner tire. Just my .02 cents

 

>>NickD....great vanity plate. If your bike doesn't make a statement your plate does!<<

That's not my real plate. I shop it when I post a photo that shows it. It's not that I'm paranoid, I'm not, but whenever I posted the real plate several people would follow up with, "Oh no, you're going to get your bike stolen!" Yeah, sure, and they're going to be picking iron out of their livers if they try. So I thought shopping a plate number on it that would be impossible to get would eliminate that. But, I guess not, LOL!

 

Yea...I'm aware it was shopped. After I looked closer with my 50 year old blurry eyeballs it was obvious...thats why I added the comment to the bottom of my post.
I would be less concerned about the bike being stolen posting a valid plate than the possibility of ID theft. People that steal ID's are very resoruceful with limited information unwittingly supplied by unsuspecting victims. I happen to live in the ID theft capital of the country.
