About 120 stock. It is the fastest stock quad ever manufactured so far and will beat a raptor 700 in both acceleration and top speed. It runs a 1/4 mile in 10.6 seconds stock a quadzilla does not go 120 stock. my friend has one that has a lot of work done to it and it goes 127. tops. a stock one goes around maybe 105. They will go just under 80mph stock and your friends does not go 127mph either, though they can be built to break 100mph. I had a Banshee that would run 117mph in a 1/4 mile.. I don't care what anyone says.. But it was built with tummy head pipes and it had cool heads and it was bored .60 over. No way? A quadzilla will go about 90 Stock. A banshee will go about 85. A raptor 700 will go about 72 accourding to dirt wheels. A banshees more top speed. Has no acceralation. A quadzilla was built to have mad tourque and the 500cc 2 stroke kicks in to give it top speed also.
Banshee ^^^ Banshee is not the fastest... Stock those bikes are pathetically slow. If you are talking in reference to top speed it's the 700r.
With stock gearing would be in the 75 mph range.
In stock form 155mph governed
