15 to 16 tooth, still need some answers
 

I bought the GZ250 for the wife and as a second bike. It is a 2009, stock. I have read most of the past posts on the T16 front sprocket but still have questions. First, where can I buy one and will putting it on affect my warrantee ??? Does Suzuki make one, if so what is the part number ?? My wife complains now that first gear runs out too fast, will the T16 make this worse ??? Is the only benefit of the T16 realize at top speed in 5 gear ??? Is this a mod that should be made for a new rider ?? Also, I have only read about changing/ upgrading the front sprocket, what about the rear ??

I thank you in advance for your help and advice Be Safe JIM

it'll make first gear last longer - most people here say it actually makes first gear "useful" - you should notice each gear lasts longer - you can change the rear sprocket too but most people just change the front - i guess it's less hassle

It'll reduce the torque so i guess in many ways it makes the bike more suitable for new riders - a bit less shifting and a bit slower off the line so more time to concentrate on other things

Suzuki probably make a 16 tooth sprocket but i'm sure someone on here will have the name of a manufacturer that's just as good and half the price - probably a JT sprocket

The Suzuki factory part number for a 16T sprocket is 27511-37200

The front sprocket is cheaper and overall easier. I have read that SunStar makes all the sprockets for OEM Jap bikes. I wouldn't doubt they make the JT for the aftermarket crowd too.

Most riders who've tried it, myself included, find it makes the lower gears more friendly and useful. You will have less torque in all gears but this will be most noticeable in 5th gear. It is a great mod for in-city, light commuting. It is detrimental IMHO to performance on the interstate, especially if you encounter head winds or hills. My bike is pretty healthy, and yet it has bogged down on a flat highway fighting a stiff headwind, forcing me to shift down to 4th just to maintain 60mph.

Ronayers.com can help you with the sprocket. Just one of many suppliers.

Re: 15 to 16 tooth, still need some answers
 

If you want the factory part, just call your local Suzuki dealership and have them look it up and give you a price.
As far as tips on the install, the How-To should cover everything you'll ever need to know. If not, there are like 15 pages on conversations after it to truly confuse you ;) Just go with the original How-To article.
