Jet-Powered YSR Motorcycle

I have been kicking around the idea for a little while of picking up a pocket bike. This is purely for the entertainment fact and I would likely go on the cheap with a Chinese version - thy can be to your door for under $250 these days! There is no sound reason for this want, just that I don’t have one. Anyway, in my online perusings, I cam across these guys called Bad Brothers Racing. In their ‘About Us’ section, they state:
The official Bad Brothers concept began in 2003, when discussing some parts that should exist with a friend and mentor, Keith. Immediately the Bad Brothers brand was born out of the laughing reference that the two use for each other of “Hey Bro”. Thus began the crazy creations that emanate from the garage. Whether it be a dream, a sketch on a napkin, or a random thought in passing the day, no idea is though of as trivial. Anything is possible in the Bad Brothers Garage.
Bad Brothers has since gone on to produce items such as the recessed tail light kit for the Suzuki GSXR, the extended swingarm kits and Pocketbike Nitrous kits for foreign made pocketbikes, and other items such as inexpensive adapters for rearset setback adjustments. There is never an item that can’t be produced. If you have the idea, we can expand on it and make one for you.
They have a current project of converting a YSR50 into being jet-powered. Check out some of the details by clicking on the links on the left side panel. They have gone through some great detail to chronicle this effort.

Other projects have included a Mini Drag Motorcycle that comes with Nitrous:

…and a 1963 Nova:

These guys seem to make some pretty cool stuff. They are also willing to run with your idea in a partnership if you do not have the fabrication means. I am interested to see the final version of the YSR jet bike. I imagine the handling may be a little tough to deal with. Whether or not I end up getting a pocket bike, I’ll know who to call to make it go faster!

Just be careful of the Chinese pocketbikes. The engines in these machines tend to be Lawnmower or other engines, and you’re not going to get the power or speed as what you would from a Polini engine.
