can anyone tell me anything?
check out a website called xr's only.com or something like that. they have pipes and parts for xr/xl dirtbikes. you might can find some stuff there.
Are you talking about the XR650R or the XR650L? Two completely different bikes, two completely different engines.
XR650R (water cooled) can put out decent power.. but it's really a torque monster. It won't compete with the 450r's both in mostly stock trim.
I'd love to see one made into a short rod, pancake piston, destroked revving machine to see what HP numbers you can get.
my geuss is a 650r put out a similar peak number as a crf450, but with a much broader torque range. it may be a little lower, but IMO the smoother power would be worth it
Yea I should requalify my response.
I had seriously looked at putting an XR650R motor into a 450r frame (back when the 450r frames were still dirt cheap) for XC, but I found that a lightly modded and ported 450r motor just seemed more capable, IMHO.
But then again.. I know my 300ex's. My 450 & 650 knowledge is very limited. ;)
Just type in xr650r and dyno in google. In stock trim the xr650r doesn't make as much horsepower as a crf450r.
Aye.. but that engine is all about torque.
With the HRC kit (on the bike, ATV will drop HP), it's dyno'd at 52.6hp @ 7000 rpm & 43.5 ft-lbs of torque @ 5500+/- rpm (it's at 42+ ft-lbs between 4500-6750 rpm.
