Changing sprockets
 

Hi,
Can anyone give me any info on changing the rear spocket. does it effect the performance or what? im told it helps speed, but lowers the torque. do you think its a good thing to get a smaller one, then i guess youd have to get a new chain or take a link out.
any help would be good
thanks

You dont need more top speed on this bike unless you are going to be drag racing for a long ways.

Anyways, Adding teeth to the rear sprocket will give you more torque but take away top speed
Taking teeth away will give you more top speed but your accelleration will drop.

Basically, you add teeth and the bike will do easier wheelies, you take away and it probably wont stand up.

cool thanks.
so would you just recomend keeping the spockets stock?

Here's a good reference for gearing.

Just to clarify .... LOL :D

Loosing teeth from the front sprocket has the same effect as gaining some on the rear, the ratio is usually about: -1 front = +3 rear.

You will lose top end speed as sacrifice for faster acceleration.

Dont forget that it also changes the speedo reading & the distance travelled readings.

I went down one tooth on the front for a certain track that I go to (lot's of turns, short straights). Let me say that you can definately tell the difference.

Keep in mind that changing the tooth count will make your chain longer or shorter (so to speak). I was able to go -1 in the front without modifying the chain. I did have to move the wheel way back though. Adding teeth in the back would correct this problem.

what would happen if you say, just for arguement wanted to be creative, and put a strange combo on a bike, would it not only cause performance damage ,but would it cause engine damage?

RE: Changing sprockets
 

Going smaller in the front does put more of a strain on the engine. I wouldn't go down more than 1 in the front.

Remember riding a 10 speed ... small gear in the front and big gear in the back is real hard to push but will make you go faster.
