CR500 

A 500cc two-stroke made by Honda. Made Between the years of 1984 and 2001. THE fastest production dirt bike around. Pumps out around 50-60 hp stock. Nicknamed "The Widow Maker" because of how many inexperienced riders thought it would be a good idea to ride it.

NO inexperienced rider should ride the CR500, they are sure to die or shit a brick.

Crf450r 

A 450cc 4 stroke dirtbike made by Honda. It is the most powerful motocross dirtbike produced by Honda with a stock speed of approximately 80mph. New they retail for over $8,000. Honda dirtbikes are superior to the competition. Driving one compares to driving a rocketship.

In a pro motocross race the best riders compete using a Crf450r leaving the other Yamahas, Kawasakis, and Suzukis in the dust.

crf250

Either a Honda dirt bike - ridden by those that can't handle the power of a proper 450 !
or a forum pseudonym used by someone that can't spell, and resorts to name calling when it is pointed out !

The crf250 is a four stroke moto-cross bike made by Honda - commonly ridden in the 125 or MX2 class.
