thinking of changing my gearing. kx 500, running 15-48 right now 1st gear does seem low enough to ride trails and single track but i want more hit and be able to pull 4th and 5th gear wheelies, right now i cant. i know stock gearing is 14-47 im thinking of dropping counter sprocket to 14 tooth and try that only with the 15 right now 1st gear seens low enough. what gearing is every one else running and type of ridding?
-
Im running 15-50 (works out to be same as 14-47)..
but my overdrive 5th is equivilant of running a 16-47 in top gear so top speed is.... well... fun...
play with this
the Kx500 is in the program (drop down menue)...

Im running 14/49 on mine. I ride alot of tight woods here in NJ.

+1, this seems to be the best compromise of gearing for all-around sport riding .

14/49.....plenty of grunt and still enough top speed to blow by just about anything

I was talking with Mr Destry Abbott a few years back, the topic of KX500 gearing came up. He raved about the 15/45 combo and how it was the hot ticket. I got a set, tossed them on, hit the desert! Needless to say it was at that moment I realized hes a million times faster rider then I am....
I've run a 13 and 14 / 45 and I seem to be sticking with the 14/45.
-
I ran 15/46 before I had the overdrive 5th.. Worked great
Actually was wishing for more on top when I has this setup.. But most was due to running a woods gnarly.. So it signed off early in the revs..

My ex-Team Green KX500 came with the 15/45 gearing on it and I like it a lot. It took some getting used to in the hills and technical stuff, but that can be solved with good clutch work. It's amazing how you can lug the motor down with this gearing and move through the desert very fast without turning big RPMs. Hopefully this will provide more motor longevity!

I tried 15/45 and it was ok for higher speed "cruising" but as you gear higher you loose acceleration. with my stock 500 engine I felt this gearing was too "mild" but those of you with modded 500's probably pulled this gearing more efficiently than me.. again it's all purely preference and individual situation.. obviously fuel economy will be far better with 15/45 as well..

13-49

When I bought mine it had 14/52 on it. Talk about acceleration! But I ran out of speed on the local GP style track. I do NOT want to come up on the faces of jumps in 5th gear in the meat of the power on this bike. I changed it back to stock since there was a 47 tooth Renthal in the box of parts the guy gave me. I like it much better. I can lug it off jumps now. It might be just a hair too tall. I will probably try 14/48 or 49 next time I change the sprockets.

Well lets see how often do you run tapped out 5th gear with 14-47. Even on dirt roads that are pretty nice I hit 5th gear and can only stay there a few seconds, wide open, back down fast to make a corner. I've always believed a dirt bike has 5 gears and a person should use all five 13-47. Most guys hit 3rd with stock gearing 14-47 and thats all maaaaaybe 4th.

Besides that 13-47 is free hp. You gain alot by gearing down. I hill climb quite abit with a stock bike no extensions with 13-47 its works good. There not to tall 400', but ledges on the way up.

so my 16-45 equivilant 5th gear is usless :-D :evil: :evil: :evil:

well motorrad I guess not useles at all if your running those kind of speeds. Out here in wyoming its pretty rough terrain, I just cant use those tall of gears. If your going up the side of a mountain, narrow road, and sink holes around alot of corners, and big rocks jetting out, I like low gears. If your pounding up a pretty steep hill full of sage brush as tall as I am sitting on top of the bike, I just dont need tall gears. If your climbing hills with rock ledges sticking out at the top, and I'm talking hills that some of the top pros in hill climbing, climb on I dont need tall gearing. I guess it depends on what your doing with a 500. If your rideing on dirt roads I can see tall gearing open country. Thats not what I ride at all. And yes last pro hillclimb I went to I took 5th place in the 40 pro masters class. I'm 53.

Mine is plated with a set of SuperMoto tires... and races Local desert... that is all... (district 38).. Fast and sandy..

And I guess on top of that the guy said he wanted more hit and 4th and 5th gear wheelies. I think is what he said. I just gave it to him. I have more hit and 4th 5th gear wheelies no problem, just crack the throttle. 13/49 gears?

16/42 but that's with a seventeen inch rear wheel on the road.

In dirt my 5th is equivalent to 16/45....

Team Green used to run 16/42 on their bikes back in the year, good for about 125-130 mph on pavement...... :-D

well I don't know about you guys but my bike had 15/52 setup on it and it didn't seem to put ANY power to the ground and felt pretty slow even on acceleration and before you could blink your in 5th maxed out then I swaped out to a 15/45 and wow is all I could say my bike accelerates MUCH FASTER through all the gears and I can still lift it in 4th just with throttle no problem and it will still rip the tire loose in 5th on the dirt too easy so I think if you gear too low It robbs all the k5s potential I'm even thinking of throwing on a 15/42 or 15/40 setup on mine to see what it does but for now I'm a believer in the 15/45 just like Mr Abbot

I guess my bikes are a piece of s**t. I have a 99 02 and 04, with topends that are darn near brand new. On dry pavement 14/47 stock gearing I have to pull on the handlebars to get the frontend up 4th and 5th gears. Guess I'll have to see whats going on, somethings wrong. Maybe have to run one up to Billings Mt dyno it. Its pretty rough country here in wyoming alot of sage brush, hills are steep. alot of rock. I can barely do it with 13/49 gears. I'm not a very good rider though. I crash alot to. Best I've done in pro hillclimb is 5th in the 40 pro masters class. I'm 52 age I guess is getting to me. Although I had a Captain in the Marine Corps give me this wooden plaque, it says "you never fail until you stop trying" ran track in the Corps, did bad at one interservice meet. I'll try your big gears, dont think its going to work though. I'll be slipping the clutch like crazy. If you see me with left arm cut off, arm pump really bad, so I cut it off. Problem solved. 47/14 gears 500mph

Hey Demo! Do you have a tach on your bike? was just curious what you are doing on the road at what speed? I was going to go 14/44, but would like to hear first hand what you think.
