I love my Banshee,and would never want a 4 stroke.Then I ride that 450 and I have to say I'm impressed.The power is crazy and it handles great in the air.The only thing I didn't care for was the seat.I do think the yfz450 will be my next quad.
I bought mine brand new from some ebay store for $150.00 shipped.It came with new cap,petcock gasket all sealed it the factory box.Shop around because there are deals out there.
