kx500 on the street
« on: August 18, 2014, 01:59:11 PM »
A buddy of mine told me that the way my bike is geared i shouldn't ride it on the road. Its a 13t or 14t on the front and a 56t on the back. He said theres too much torque and i would ruin my gears, true or not?

I dont know if it makes a difference but it has vforce reeds and a pro circuit platinum pipe and exhaust, other than that its stock.

I'm not clear on the original question.  Are you referring to the k5 not having a cush hub?

My friend said that the way my dirt bike is geared, i have too much torque to ride it on the road. Said I would ruin my tranny

I'm not sure what a cush hub is

Cush hub is rubber buffers that dappens the shock/torsion applied to the rear huband by extension the nipples and spokes and rim....like on a klr650 (best enduro in the world).

If u dont use a tire that gets a great deal of traction...u should be fine as far as the rear hub is concerned...

with the stock gearing 14-47 you could ride it on the road thats a good compromise for everything...  if you want to have a faster bike you have to gear it up to 14-40 or simply add a 15 or 16 sprocket to 15-47 or 16-47 ... 

you could simply calculate the rate of the gearing that you want. divide the rear sprocket and front sprocket.

for example:  47 / 14 = 3,357  thats the gearing rate.
 if you want a faster gearing the rate must get smaller like: 47 / 15 = 3,133 
 if you want more torque for offroad or mx, the rate must be bigger like 50 / 14 =  3,571

and now i wish you much fun by testing the right gearing for your needs...   8-)

Be carefull about running a 16T front sprocket, I tried it when I was goofing around with gearing for high speed ice runs, and you can't run a 16T on a stock case. The sprocket guard bosses interfere with the chain. If you want to saw off the posts then you are ok. The biggest I could fit was a 15T. You have a ton of choices with the rear , so no real need to run a 16T up front. I ran 15/45 and that was pretty good for high speed blasting at lesser rpm's on logging roads. Keep in mind as you gear higher for speed you loose a fair amount of acceleration..

Running a 16T on my Supermoto....
No issues except I had to move my shift lever down a spline or two so I didn't grind it while up shifting  :-)
