Extreme power-to-weight

Weight. The ultimate enemy of any speed junkie looking to extract every last bit of performance from their machine.

More power, less weight. It's always the endless quest of power adders and weight savings for any racer or wanna-be since the beginning. So this madman takes a R1 powerplant and bolts it on to a go-kart chassis. What does this misguided feat of blending net? How about 180 hp on a 220 lb platform? That enough for you?

That's a power to weight ratio of 0.818. Add an averaged sized driver and it goes to 0.429.
For comparison, a '12 BMW M3's ratio is 0.112. Includes airbags.

Gallardo's is 0.153. Includes stability control.

In 2011 an F1 car was .0496. With aero downforce and a carbon fiber monocoque for safety.

So what does all that mean? It means you have a really fast, somewhat deadly, ridiculously fun way to outrun cops in your neighborhood. Sitting on a chassis an inch of the ground with a motorcycle engine basically strapped to your back. Truly insane blending. I love it!

Seems pretty safe, right? So what if most cars and trucks can't see you because you have the profile of a toddler on a tricycle playing in traffic. I guess the move is to go to an abandoned airstrip and really stretch it's legs. What could go wrong, right?

I gotta get me one of these!
