a car that can beat a comparable bike would be an ariel atom, a formula car, or something else with lots of downforce or little weight. I've only been riding a little over a year and a half and I can take my gixxer just as fast as my mustang (w/ irs) in most places, and it will absolutely dust any car on the road on a short strait. you chasing down guys on canyon roads can be explained by a few things, they're not trying as hard, they're inexperienced, or they just know their limits. pushing a car on a canyon road is way different than pushing you're bike. doesn't make the car faster.
The Ariel Atom has recieved alot of press attention. I wonder why KTM's Crossbow never recieved the same amount of attention when it was released.
