The fastest stock quad is a Suzuki quadzilla. It has the highest top speed. But not the moosy tourque. The fastest 4 stroke quad is probably either a polari outlaw 525 in tourque but a Honda 700xx in top speed.
I have a yfz with a trinity stage 5 exhaust system,ac pro peg Nerf bars,maxxis razr 2 tires front and back, elka elite series shocks front and back, pro ATV intake, axcalibar axle, and lonestar racing a arms. I went 5 gear all the way on a street by the radar thing and got clocked at 98 mph. YAMAHA450- that is not stock...mine is completely stock and it runs 88-92mph depending on the weather.
Cole Gaucher and Alax Pouteaux made the fastest quad in 2007 maxing out at 250 km h
The DS450 will take it to 89MPH @ 10500 RPM topped out. That's Completely stock. lightly modded ds450 engines (cams,air intake, CPU,and exhaust) have been clocked at 93.....this has been the fastest 450 sport quad since 2008 to the present.

the yfz 450 is not that fastest quad, Its not far from the top but raptors have more top speed. there is no 250 that will stand up to a yfz 450 stock
the fastest stock 450 ATV is the ds 450 by can-am.
