I just bought a 2006 V2K Classic a few days ago. I love the bike, its an awesome bike.Just takes a little bit to get used to pushing it around and walking speeds. Something different from sportbikes and dirt riding. Right now it has a 200 tire on the back, but I think I read somewhere where you can mount a tire as big as a 240 on the back. Does it fit, and will it work on the stock rear wheel? Also are these pretty loud stock or not? might has a nice rumble to it, its loud, but not to loud, sounds just about right. It looks like the stock exhaust but maybe the previous owner just did something to it with baffles?
