I need your opinions in what size tires to buy for my 250R. I have 18" tires on it now and I'm running stock gearing (13 front/42 rear). I want to have more top end speed and not have to ride in 5th gear everywhere. I was thinking about getting 20" tires and buying a 14 tooth front sprocket. I thought this would get me closer to what the stock setup was with the 22" tires. I thought a set of 22" tires might make it look bad. What do you guys think I should do? I don't want to order 20" tires and wish I bought 22" tires.
