What is the Worlds Fastest 2009 sport ATV?

Answer 1

The 450cc class is the most popular sport ATV class, but not the only sport ATV class. Most racing leagues have more than just a 450cc class, for example the "Open Class". In the Open class, riders of any skill level and any engine size can compete in the same race. If you're asking for the fastest 450cc sport ATV, it will be very hard to come up with an answer because of how close the 450cc sport quads are performace and technology wise, it would basicly be a matter of rider opinion. Though in my opinion the top three fastest 09' 450cc sport quads in stock form are the Yamaha YFZ450R, KTM XC/SX450, and the Can-Am DS450. If you mean the absolute fastest sport ATV regardless of the class, you will need to consider the Yamaha Raptor 700R, The KTM XC525, and the Kawasaki KFX 700. In a magazine article I read last year the KTM 525 beat out all the competition in an overall shoot-out, since it was in a reliable magazine (Dirt Wheels) I would think the fastest 2009 sport quad in stock form is the KTM XC525.

The fastest four wheeler is either the Can-Am 800 Renegade, the Arctic Cat 1000 Thundercat, or the 700 V-Force. Either one of those, im not sure exactly which one, but i know that all of those have speeds of around 145 km/h plus.- the lt500r quadzilla is the fastest quad of all time 100mph stock. and my brother has a kfx400 with a few upgrades and it kills raptors, they are the most over rates quads today.
