if i keep the stock 16th on the front and put a 45th on the rear what i can expect this bike to do? Top Speed? what kind of acceleration? Will the front end come up in 1st with just the throttle?

slight acceleration, slightly less top speed, probably not a wheelie machine.

use search for sprockets I believe there are 5+ topics about this.

This is correct information. Going up in the rear or down in the front will increase the gearing ratio, causing a boost in acceleration at the expense of top speed. a 45 in the rear will be noticeable, but not a wheelie machine.

You'll probably have to get a longer chain too... just go down in the front... -1 in the front = +3 in the back.

Re: Quick Gearing Question Clarified

Yaknow It don't mean diddlly to me, but in the intrest of accuracy. Hey that's my job.

Gearing is simple math (even you can do it). For the 2nd gen bikes.

Stock Gearing : 16 /41 = 2.5625

one down : 15/41 = 2.7333

3 up in back : 16/44 = 2.7500

It should be evident that Items 2 and 3 are not equal

If you need help doing this for the gen 1 bikes call Shorty 4444 he's unemployed and need the work.

as we found out in the wheelie thread, not all EX500s have the same stock gearing (for whatever reason). the front is always 16T, but the rear varies from 41 to 43.

Seems rear sprocket size changed in 94 with the tire dia change, makes sense to me. The 87-93 have 42T rears and 94-07 have 41T rears, they all have 16T front.

Sprocket Specialists catalog shows same.
