Do any of you have a 2by4 Scrambler? If so how fast are they?

 

PLENTY FAST !!!!
Throw some parts on it and take the time to tune the combination, and it's a rocket. I'll NEVER wear out the front tires, they only touch the ground when the quad is sitting still !!!!
This is a 500lb quad with a 230lb rider plus gear....
It should top out in the 60 to 70 mph range, I haven't put a GPS on it yet to get some firm numbers.
I really enjoy mine, and would recomend one to someone that wanted REVERSE.....

 

Pretty fast, but I still was easily passed by a DS-650 last weekend. (no, I'm not surprised) About the same on top as my friends 400ex.
