Hey Boys. I'm looking for a little more umph from my 9R. I wonder if it is better to drop a tooth in the front or go 1 bigger in the rear.

Do you get the same effect if you change the front or rear.

Wouldn't it make the bike a little more flickable by going bigger in the rear, cause of the slightly shorter wheelbase?

Thanks..

Man Here we go again. Drop -1 tooth in the front. Its easier and if you do its like going up +3 in the rear. if you just go +1 in the rear then its not gonna make any difference. I did this on mine a month ago and it revs out a lot quicker. goto www.sprocketspecialist.com and get your sprocket from them. they are cheap and hella fast when it comes to dilivery. I paid a total of $21 including shipping for my front steel sprocket.

Dropping 1 tooth up front is = to 2.75 teeth in the rear +/- If you are going to do that consider going to a 520 chain & alloy rear sprocket which will reduce both unsprung weight as well as rotating mass. You can do the whole thing for about $160.00 in parts from http://www.kneedraggers.com

I agree with highalt. I got my 520 kit as he described retail (locally, not online) for $161. Improved off the line but I really noticed a difference in roll-ons.

If its a cheap mod. your shooting for then your on the right track. Go -1 in the front and your dealer should stock the sprocket, I got mine for $15 at a local dealer. Youll need a air ratchet to get the bolt off the sprocket, a friend of mine put a bar between the spokes of his rear wheel to keep it from turning but I cringe everytime I think about it.

Ordered both front and rear sprockets for my 12 from Sprocket Specialists. Paid, $106 inc shipping, and got the Titan Tough hardened coating for the rear one. recieved yesterday and to be installed when the new tyres go on.

+1 rear, -1 front.

This sounds like something I have to try. I definitely would like a little better roll-on power. This sounds like a really simple mod that will give some nice performance gains. I hate to assume things, so I am going to ask this question. Do you need to make any changes in your chain from stock if you are just dropping one tooth on the front?

Thanks for the info!

You don't have to put a bar/pipe in the rear tire to keep it from turning while wrenching on it, just put it in first and press down on that other thing on the opposite side of the bike, I think they call it a rear brake lever /images/icons/cool.gif
The rear break, this may be the only case actually come in very handy, and will hold the back wheel from moving.

I put a -1 front tooth on my 97 9R and I love it. You have to be careful in first and second gear, the bike really wants to lift the front. But, that is a good thing /images/icons/smile.gif.

i recently went +2 in the rear on my 6r. i know that -1 up front is more popular, but i love the difference it has made to my bike. third and fourth gears pull so hard now.

All I did when I changed mine was use a 1/2" drive ratchet and holding the rear brake. Piece of cake. But I did change both, and go with a 520 setup.

I went down one in the front shortly after I broke the bike in, and I've never been disappointed...I changed out the sprockets for Renthals and put a new chain on around 10-11k miles..
