You will have to rejet. Your peak power will increase very little, or may actually drop. If you are lucky, you may realize some gains in the midrange, but then again, you may not. Your bike will be louder, which may lead you to think it is more powerful.Your gas mileage will almost certainly suffer.

The only reason I considered the 19" was for more float off-road. I said to he## w/ it. If the experts on their seriously big bad bikes use 21" and 80/100 and 90/90s up front in the desert, so will I. It was never an issue for street action for me - always soft off-road issues. Just before I disassembled my bike for a complete rebuild (expect motor) and upgrade of various items, I began to get a bit more aggressive in soft dirt and carried more speed. Just like 25+ years ago, it worked. I can't air down to much due to rocks, so when in doubt I got up and back, and ran higher speed. The 'rudder' analogy proved itself quickly.

Contact patch changing, geometry changing, weight changing, etc. But you have to ask yourself one very important question before you go off spending alot of money on changing your front wheel size/tire. What are you lacking right now, that you need that new wheel/tire to do? Traction? You mean to tell me that your sliding the front Avon Gripster on the stock wheel all over the place?? I seriously doubt it. Turn quicker? You mean to tell me that you are finding that you just can't turn the bike fast enough with those wide ass bars?? Your now turning it from scraping the right side peg, all the way over to scraping the left side peg, and you've been doing it for a while now, and you need to do it FASTER?? Again, I doubt it. I have been told by a few guys, that have followed me ripping through the mountain twisty's, "Just think what you could do with a supermoto setup"! (19" front wheel) So I did think about it......and I couldn't find anything that I would gain. With the Gripsters, I have done, and do the above on the street. I am still amazed at what that front end will do and not lose traction. I actually get pissed off and just start haphazardly "throwing" the bike HARD to the left and right TRYING to make the thing slip or slide and it just has not happened. I did manage to break the back end loose by doing that, but the tire was shot, I was leaned over to almost the peg, and I was giving it alot of throttle. That's when I tossed it down the road at 45mph. The front never budged though. So am I missing something here? Can I get THAT much more better street action out of a 19" wheel? I'm thinking that if you have already done ALL of the other things that you can do to the suspension, and have spent the time tuning it all to get it just right, and you are riding around like you just stole the thing, leaning it over to the pegs, and counter steering it as hard as you can, you would find that you just don't need anymore.
