[Vegas Street Rider]

I went with the 16 tooth front sprocket on my '09' GZ and have generally been satisfied with the top end speed of 75 on the flat with no headwind. I installed it not to increase my top end speed but to lessen the strain on the engine and thereby increasing it's life span. Each bikes performance will vary a little bit, but you might get a little more out of it by tweaking the carburetor, changing to a different spark plug, etc. Don't expect to get Lamborghini performance out of a Chevy Cruze. Some of the other members will probably come on and give you some additional advice to help out but if you need more speed you might want to upgrade to a different bike.

Check the performance section for tips as well.
