My name is Josh and I just rid of my 2002 YZ125 and I have been wanting to get a 4 stroke. I dont want to settle for a 250 or anything but rather go for a big bike with speed. What are the years for the Xr 600 to the Xr 650? I have always been a Yamaha fan but just wanted to check out some Hondas. What is the top speed of a stock Xr 600 compared to a stock xr 250? My buddies and I vasically drag our bikes and it sucked with a lil 2 stroke 125 which i ended up blowing up. Please help me figure out which bike I should get. Thanks.
