if you plan on fishing with this, listen to him, I have a belt driven vinson that I would put up to his 400z anyday of the week. Look it all depends on your needs or wants, any vinson is a great bike, we just need more info of what your intentions are...then you can decide what is right for YOU....Don't listen to guys with track bikes....MUD is GOD!
I have an 06 Vinson auto, it's belt drive, and I have never had any slip unless I was in 3 feet of water and then not everytime. I bought this bike new and enjoy it everytime I ride. The vinson has really good gearing in it. I can go places in 2 low that my buddies can barely go in 4 wheel drive. Very good dependable bike. I ride hard and it has never let me down. I am now needing to finally adjust the valves. 6 yrs old and still needs nothing. Executioner tires will get you where you really shouldn't be.
i had a 2007 vinson auto which i bought new. put almost 15000kms on it and replaced the belt once, at 3000kms when a seal went in the transmission and let oil in around the belt. awesome machine and tough as nails! would recommend one to anybody.
