    2007 CR 250

    Winning championships for over 30 years, including the first-ever perfect season in AMA MX history, the CR250R is simply the best 250-class two-stroke that's ever been. Awesome two-stroke power and ultra-trick, aluminum-framed chassis technology combine to create a machine as potent as it is nimble. Which is why you should ride one now—or chase one later.

    Last of an era... :( I think Honda is making a big mistake cancelling all their 2 strokes.

    Have fun with it. Track or trail riding? If you want to try desert racing let me know.

    electronically controlled RC valve, Man I feel like I have been hidding under a rock. When did they stop making them with read valves?

    Wrong end of the motor. The RC valve is what Honda calls their electronic exhaust powervalve. It still has reeds.

    All the other brands still use ball and ramp style powervalves.

    Nice bike, i think fourstroke is the future.Shure two strokes have there place and nothing is like hitting the powerband on a 2 stroke but i know a guy who raced a 250r for years and he rode my 450 and was hooked, he came off of the track and was like "HOLY SHIT i need one of these"

    Nice bike. Congrats on owning the end of an era. Won't be long before these things become collector's items.

    all I care about... are the 4 stroke engines quieter?

    All depends on the muffler... but for the most part, CRFs and YZFs and other racing four-strokes are much, much louder than two-strokes. Especially with most aftermarket silencers.

    Not to mention the lower 4-stroke exhaust note carries much further.

    yes four stroke can be loud as fuck if not muffled properly. A good muffler with good packing in it will sound very nice. Some two strokes not muffled properly with shitty or no packing will be loud also. go to a mx track and listen. A lot of fourstrokes are loud but so are the 2 smokers:naughty:

    not the same thing.

    the rc valve is an "improvement" of the normal power valve on a two-stroke. that's honda for you.
