CRF250 CRF450 CRF250x CRF450x

Ok, I am about to make the jump to 4 strokes, but,,,, I need some input from
others in the biking sport. I have a 95 YZ250 with a smaller front sprocket
and heavy flywheel. This does pretty good for me off road.

I rode my friends 2004 crf250r which has a dry weight of 206 and boy could
you tell it, it had plenty of power and I went faster then I had ever gone
on my YZ with no effort. Id love to get one of these but I am not sure how
they will do going up a 45 deg hill at 13,000 ft. My YZ barely chugs up some
of those Colorado mountains. I talked to a couple guys and they said the
crf250 loses less power at altitude than a 2 stroke and up there the 250 4
stroke actually felt like it did better because of the higher torque.

So, I could get a CRF450 and add about 17 pounds and gain heaps more power,
but... is it the type of power that Ill never be able to actually use and
then have a heavier bike to boot? I can get a used 450 for $4000 while a new
crf250 is $5200. I have heard the crf450 is not good off road unless its
geared way down. Also I heard the 450 needs a lot of maintenance including
frequent top ends....

crf250x, wide ratio , less power, same weight as the 450r , 222lbs ( doesn't
sound worth it) . crf450x, 455 pounds dry!!!! I think I'll rule that out
unless it comes with a center stand, reverse gear, and heater.

So here's the question, I'm 192 pounds without gear, I don't do motocross
tracks except for hare scrambles. I have 20 years of riding bikes under my
belt and am looking for a bike that will be more fun to ride and able to get
me anywhere my YZ could get me, yet one that handles like a new geometry
type motocross bike that is able to hook and corner with the best of them.
Top speed that I need is about 55 mph. and the ability to climb steep grades
over 12" rocks at 12,000 to 13,000 ft altitudes. Yet (always the yet) be
able to go to Rampart and play in the nice smooth corners handling the
occasional jump or whoop.

crf450x, 455 pounds dry!!!! <<<<< Recheck that number I think it's heavy
by about 100 LBS


The group of bikes you are talking about are all great bikes. I ride a 450
in the woods and also ride a bit of MX with the same bike. Great machine in
bothe areas. The suspension soaks up the big hits offroad and still light as
a feather on the track. I have added an FMF PowerBomb header, Race Tech
Flywheel, Works connection Skid plate, Engine Guards, kick stand, MSR bark
busters, Notoil filter and a few other goodies. The only thing I change when
riding MW is Bars. I have my woods bars cut to 28.5 inches.
