Steel.
Steel seems to wear longer, but some like light weight aluminum. Now you can get an aluminum center with steel outer sprocket.

I have a 05 honda cbr 600rr, im looking at changing the chain and sproket. what size and lenth and all that stuff do i need to get


1st. - NEVER change sprockets without changing the chain..and vice-versa!! - they need to be replaces as a set...they wear our almost equally.. ie - a worn out chain will wear out new sprockets... A new chain will get stretched out by worn sprockets real quick!
Its east to tell what you have...
  • OEM sprocket size: 16/43 - 2.68 ratio.
1. Count the teeth on your front sprocket.
2. Count the teeth on your rear sprocket.
Compare yours with stock(OEM)..
Now, if your sprockets match the stock sizes - count the number of links in your chain...(count the inner links).
If the sprockets are different sizes you adjust the chain by that number using inner links. - Usually people go smaller on the front or a larger rear.. this increases the ratio to give a quicker take-off - (more acceleration).
15/43 = 2.86
15/44 = 2.93
15/45 = 3.00
15/46 = 3.06
..when you get a new chain... better to get one a couple links too long than one link too short!!
Your local dealer will be more than helpful!!

Can you change tranny gears to decrease rpm's on highway? Or maybe change sprockets.


You can add teeth to the front sprocket or take teeth off of the rear sprocket. In the case of your bike , I do not think there is a 17 tooth front available so your best option would be to shorten your chain and drop from the 44 tooth rear sprocket to 40 tooth or a 36 tooth rear sprocket. That would be like adding one or two teeth to the front sprocket. Your stock is 16/44 so decrease from there. Be sure to ID your chain, get a chain breaker, and a new master link.

07 YZ450F First gear is to tall but then it peaks out to soon along the long trail,wil changing the rear sprocket down a tooth help ?


Find out what the tooth count on the rear sprocket was from the factory and see if you have a smaller sprocket than stock. THIS WILL BE FOR A FASTER TOP END.
a larger sprocket will give more power /rpm less speed.
GOOD Luck

When shutting down throttle in gear, a heavy clonk is felt through transmission! chain and sprockets good.! thankyou.


If the chain and sprockets are in good condition and adjusted properly ( 1 1/2" slack ), you should check the rear wheel sprocket dampers. These are made of rubber and can deteriorate over time. If the dampers are bad you will be able to move the rear sprocket forward and back while the bike is sitting still. It is an easy fix to replace them, just remove the rear wheel and sprocket. they are model specific parts and should be available from your local dealer.

What gearing for honda cr 250


Usually, it seems that changing the front sprocket is more cost effective and easier to do. The front sprockets are about $10-$20 and rears are normally around $40-$50. Usually 1T gearing changes made to the front sprocket are the equivilant of a 3T-4T gearing change to the rear. I personally would go up on the front instead of down on the rear. Right now your gear ratio is 3.846 (meaning every 3.846 rotations of the front sprocket, the rear sprocket makes 1 rotation) If you go down 2T in the rear (13/48) your gear ratio would be 3.692 giving you a little less torque and a little more top end. If you go Up 1T in the front (14/50) your gear ratio would be 3.571. This would be about the equivilant of a 46.5T rear sprocket. (If they made it) The nice thing about doing the front sprocket first is the cost. If you decide it's too much difference and you want something in between, you can put the stock 13 back on and then change the rear (and you would only be out the $$ for the front sprocket) If you start with the rear and decide it's not enough then you change the front you're out the $$ for the rear.

Speed increase


I had a small Hyosung 125cc Easy Rider before and it could not go more than 110km/h no matter how hard I tried. So I found the cheapest way to add on the KMHs.I checked my rear sprocket and as i remember it had 45-47 teethso I changed it to a smaller rear sprocket of 39 teeth and immediately I could get an extra 15km/h to it.So an inexpensive way is to reduce the rear sprocket size.It cost me a mere USD3.50 for a local made rear sprocket and some tips to the mechanic. No need to spend a bomb on NOSTURBO etc.,,
