This sort of thing is starting to pop up in more places, I just wish more of them were popping up where I live. The R1ot, is a purpose built track day car powered by a 150hp Yamaha R1 engine. And if you're wondering about performance, the total package weighs 410 kilograms, that's 903 pounds! I'll bet some Harley dressers get close to that weight. Built by Sylva Autokits, a company that's put together a lot of very quick and successful track cars, they look like they have another nice one.
