I did some testing of friends quads last night. Using a gps and I'm assuming that it is accurate.

400ex Honda. Completly stock right down to the short rear tires: 68.1mph.

KFX-400. Stock except for a dial-a-jet: 66.3 mph.

Yes folks the old aircooled Honda walks away from the KFX/Z-400! Who wooda thunk?

 

Here's another one. My 82' ATC250R. It's completly stock except that It is geared for speed.

I replaced the chain and sprockets a few years back. The bike shop did not have the stock gearing instock so I ended up with +1 on the front and -3 on the rear.


Even with this gearing it tops out at 56.1 mph using the GPS.

 

pallease my sisters moto 4 would smoke all of these quads its bone stock and does 36

 

and u take u take a z/kfx/dvx out with a 400 ex for a stock drag run the z is gonna win i dont care what dream world u honda meatheads are lving in

 

im saying that myself owning three hondas stock the suzukis are faster

 

The Z/KFX is faster in a drag race but the 400EX has more top speed. This thread is about top speed and not acceleration. I was able to ride next to my friend on his Z-400, I was on another guys 400EX with my GPS in my left hand. Once the Z ran out and could do no more I still had a little bit left on the Honda.

I ride a Green quad and thought that the Z would be faster, I also thought my 250R would be faster.

The GPS does not lie.

 

I did 96 paced by a 99 Durango R/T on a backroad, stock sprockets.

 

I clocked in 49 mph on my Yamaha BearTracker and that wasn't its full speed the stip I was on wasn't long enough to get up to full speed. I t can probably go up to about 60-65 mph.

 

70 on the efi

120 on the 600 xcr

 

What in the name of all that's holy have you got done to a Beartracker to think you'll get anywhere near 60-65mph?
