There are many veriatys of bikes from the basics Kawasaki, Honda, Yamaha and Suzuki.

Then there are the top of the line. Cannondale, Gas-Gas, Cobra, KTM and tons more. I can only offer info. on a few of them.

First the cannondale its made in the U.S.A. in fact it is made right here in this state. (Bedford, PA) tis is probably the most technologically advaced bike on the market.

Honda

Honda is probably the most well know. Which does'nt mean its the best. The biggest problem is it is a Japanese comany. Often used in pro races.

KTM is one one the best. Made in europe and mostly a offrad bike not racing.

The Kawasaki is one of the better 80cc to 100cc class bike it is not popular for pros. Made in Japan.

Yamaha

Yamaha is one of the most well know bike companies. Like Honda and Kawasaki Yamaha is made in Japan. Although it is one of the better designs.
