I am a newbie when it comes to identifying bikes even though l have been riding a while. l have always riden xr's
l should probably be more specific;
What is the difference between a crf250f and a crf250r?

CRF250R is for motocross. CRF250X is an off-road or trail bike. You might be thinking of a CRF230F that is kind of a play bike.

Basically the 250 R & F share the same engine & frame. The ''F'' would have lighting for night riding & dark trails. It also has a kickstand on the swingarm & different suspension set-up. It may also have different gearing in the trans. & cam timing timing. The R is a motocross racing bike. Looks the same, but, totally different beast. Honda is website would be a good source for info. l think Honda might be coming out with a CRF230L which l think will be street legal.

A right, l think u mean is a crf 250x vs a 250r both r four strokes, both r built for motocross track. the only difference is the the 250x is a motocross bike made for the trails; it has lights, electric start, a different gearing.

XRs r pit & trails bikes they r not really made for motocross, but with a 250x u can have the luxuries of a motocross bike (crf250r) with the inverted forks, powerful engine. & the smooth fourstoke power combined with the essentials for trail riding, the lights & stuff.

l think you may be confused as when people talk about the 250f is they are generally referring to the motocross version of 250cc 4 strokes. l guess that is confusing when as Jared and Mitch have pointed out that you can get a crf250x which is the the x is more for trails where the R is designed for mx.

Like the others said, Honda makes a CRF250R (motocross bike), CRF250X (woods racing bike) and a CRF230F (trail bike). The term 250F is just a generic term applied to all 250 4 stroke race bikes.

the f is off road bike. its not for racing its for woods. the r means racing. those are the motocross bikes

well the cosmetical diffrences are
250R-one exhaust pipe, a big thick pipe on the upper right side
250F (CRF)- if after 2006 (i think) 2 exhaust pipes, small pipe on upper right side

sound diffrences
250R- higher pitch, more like a chain saw
250F- lower/deeper

feel
250R used to race with the 450s so more powerful than the 250F, has much more giddyup mostly power up high on powerband, have to pull in clutch lots
250F not as powerful but still plenty more power down low, can get out of corners easier

thats just the basic diffrences
