Hello everyone, I've been trying to sell my 05 crf250r for weeks now to fund a bike for my fiance to ride on the street. I had an offer of $2100 but didnt take it. I was thinking of calling the guy back and axcepting his $2100 til an offer came through today. Someone wants to trade me an 03' yamaha wr450f. It is in excelent condition, and has 800 miles on it. Is it a fair deal??? Also I want to make the wr450f street legal. I saw kits for $160 on ebay, anyone used those kits before. I also want to put road tires on in place of the dirt tires. I need to know the biggest sized tires I can sqeeze onto the stock rims. Any help would be great.Thanks!
