You can determine the year by the serial number. I think they used to use the year and the number within the batch. Yours is probably around a 2000? I've used fat tires and I've used skinny tires. Fatties were good when I was running fairings but between the tires and the fairings the bike handled like a tank. These days I'm running 1-1/4 in back and 1-1/8 in front. Mine is a 1997 V-Rex24.
