Maybe most of us are smart enough not to ride a custom built 170HP ATV at 125MPH down the road in shorts and a tee-shirt but this is the internet and we should never underestimate human intelligence:

What an idiot. If he hit a car at that speed he'd be dead and it could easily happen, especially when he was driving to the left of the yellow lines.

 

I bet he has sandals on and no helmet too.

 

Probably has a helmet because you have to have something to mount the camera to. Sadly that's probably the only reason he's wearing one. Yes we see quads can be made to go this fast on pavement. Should they, well no. A street bike is designed to be ridden on pavement and just about any of them will go faster than this. I'd kinda like to get a Can-Am Spyder as I think the riding experience with the 2 tires in the front would feel very similar to riding a quad. You'd never have to worry about dumping it on loose gravel or wet roads like a normal motorcycle. In fact, you wouldn't even have to put your feet down to balance it at stoplights, which I can imagine gets annoying at times. But the price for even a good used Spyder is close to 10K so probably not happening. I like the semi-auto electric shift option too. With the 1000cc v-twin, I would think it would have plenty of power.

 

I just realized this quad has almost double the horsepower of my friend's Sportsman 1000.
