Down in the front, or up in the back??

I'm looking to get a little more launch and easier wheelies!

I'm not too worried about my top end considering I don't need to be going 180 anyway.

What is better one down in the front, or two up in the back.

About how much does this cast?

Thanks in advance for any help!!

Nothig wrong with both. Down in the front and two up in the rear will make a significant difference. But just down one on the front will make the magic, too. Don't forget to get a speadohealer as you want to clock real mileage and correct mph.

So you think changing both is better?

How much of a difference is it from stock?

My cousin has the same bike as you pyro and he was thinking about changing his to wheelie better too.

i would not switch to 520. the chain stretches too fast. as far as top end I would GUESS maybe 10 mph. depending on how many teeth changed.

By the calculator with a 190/55 rear tire, mine should top out at 173. I think that's plenty.

Check out this site. It will help you see the impact of changes on the front sprocket versus rear sprocket and even tire size. You can also see the speedometer error.

Going down on the front sprocket = +2 1/2 not a full +3. Front sprockets are cheaper. But by changing it out you'll put more stress on the chain and motor.

Another + on just going down 1 in the front is that you don't have to get a new chain.
