Technically, yes...but they're called quads and are OHV only. There is a vehicle I consider to be a sport bike with four wheels, it's called a Lotus Esprit; but it's only 2wd.

 

I'm kind of a sport bike guy but I have ridden a few harleys. I own a 09 Suzuki GSXR 1000. I included a picture....

 

Thats an 08 fyi.....

 

I started out on a sport bike but am working my way to get me a Harley or build me a Bobber.

 

I like the cbr f4i just because the frames can handle getting slammed on the ground all day without cracking

 

Especially if you throw a 905 cage on them!

 

905 is a pretty sweet cage, but I like sick innovations

 

who needs a crotch rocket?
when you have a super bike?

 

I just bought an 86 Radian the other day. It's my first street bike and it only has 6,000 original miles. It's a little small for me but it goes like hell. The snow came off the roads yesterday so I took my first ride on it after work.

 

Someone say Superbike Here's my 99 Ducati 996s
