RE: Advantage/Disadvantage of smaller front sprocket
I was told to think of it like a bicycle chain, the smaller the front sprocket the easier it is to turn the chain.
BUT supposedly the stock front sprocket is dampened and most replacements (If not all) are not dampened. Therefore you will get more lash with a smaller front sprocket.
Most around here go to a larger rear sprocket instead. -1 in the front = +2 in the rear. So you can go up two sizes in the rear and get the same effect.
Also you will lose top end with this mod but since most don't go up to 180 on a regular basis its usually not a big deal.

RE: Advantage/Disadvantage of smaller front sprocket
There's no "lashing" or anything like that. You just get a little bit more vibration. Hardly noticable. I went down a tooth on my front a few thousand miles ago and love it! i noticed a little extra vibration for about 50 miles, but it was so minute that i quickly got used to it. Deff the best 30 bucks you can spend!

RE: Advantage/Disadvantage of smaller front sprocket
Sorry my bad. I read it on here somewhere that it vibrated more and the stock did not . I guess thats not the same thing.
I know many of you go for a -1 in the front and a +2 in the rear (At same time), or +2 to +3 in rear only, or -1 in front only.
Any reason for one over the other if the vibration is not bad? Is the only reason to be able to keep the stock chain?
Would going +1 in the rear do anything noticeable?

RE: Advantage/Disadvantage of smaller front sprocket
you wouldnt really notice a lot with just a +1 in the rear.
-1 in the front will change the gear ration like a +2.5ish in the rear supposedly.
popular is -1/+1 or +2 and going to a 520 pitch
vibration isnt so bad, the oem one is big and heavy (i lost a half a pound from oem to a 15T 520 one)
so it cuts down on any vibration. the new one will buzz you feet a little if you are wearing sandals or sneakers but I have never noticed any vibration in my Astar boots. a too loose chain will cause more lash than this mod.

Plus your speedo and odometer will be offabout 10% high with the gear change...so you need $100 for a Speedo Healer!!!
