Maintenance & Technical > KX500 Original
Power question
bigbellybob:
yes the new 300's run dang good. they should have no problem running with a stock 500. they have the torque and hp of a 450. also watch out for updated 380's there is a lot of them out in the world now. i personally know of 10 not counting my 2. and i have no problem telling someone that just got smoked ether of them is just a 250. there is even a hand full of 380s sitting in the 07-10 frames.
a stock or slightly modded cr or kx 500 is no match for the bike on the right. and most people will believe its just a 250.
my 2 380's
RoostDaddy:
I'm not sure we have any 300's around, but there was a 380 and a 250 with a 380 top-end running with us. Both of these bikes were no match for an ordinary 250 and could even hang with some 500's. sorry i couldnt give any info. on the 300, but I will agree with BOB that the 380's are quite impressive.
Motorrad:
My vote is on the back tire. His was better. Put more power to the ground
I have run into times where my 250 will hang with my 500 for a while as the 500 is blowing the tire...
Mostly on hardpack with a dusting of loose dirt sand over top is where they will do it...
3Razors:
On flat ground a well tuned 250/300 will give a stock 500 a run for the money...they rev high. It all goes back to the rpm vs torque debate.

Thanks for the help guys,
I think all of your points are valid especially the torque vs hp point. I would get up to speed much quicker but the 300 would seem to rev out and catch me. I seemed to run out of revs. I wonder if I ran taller gearing if that would make a difference.
If I did some of the recommended mods for power, would it give me a big jump or just create more wheelspin with less rideability?
I feel sick even thinking about itas I love the 500 but I'm wondering if it might be time to move onto some newer technology.
