kx500 vs crf450
YUNGGUNNAZ:
i've seen crf500 do a number on some modded k5's in 400ft.weight,rider ability and actual bike setup makes a big difference.pick a distance to your advantage.
YUNGGUNNAZ:
i meant crf510.
Fowler Racing396:
u talking bout ricks 000 bike? that thing is quick. . .put down alot of 500's. .
BDI:
If the bikes have ample power to pull the riders that are on them then there are some other things to think about. If both bikes rev up at about the same speed/build power at the same rate, the gear ratios are close to the same you may not see a big difference between the bikes on flat asphalt. Infact the crf may beat you on top end if the two bikes have close to the same final ratio do to the crf turning more rpm. You need to load the bikes to show which one makes more power. you can do this by putting a taller gear on the kx500 or running the bikes up a steep hill. your 1/2 ton chevy pickup might be just as fast as your buddies 3/4 ton duramax but put a fifth wheel on bolth truck and then see which one is faster. You should go up one tooth on the front and down one tooth on the rear from stock and then tell him you want to race 500' for $500.

Out on the trails and tight stuff the 450's are fast. I bought the 09 red one from a friend with fmf mega bomb and carbon silencer and that bike just screems. I also sent the ecu to tokyo mods and it got a little more on top. These bikes really rev and with the efi almost always make power. I think that if the k5 is running well you should have little proble though.
