JT Front sprocket with 16 teeth (+2) from stock, gives around 12 % increase in total drive ratio. Selling because I got a 15 instead !

PS: You need to modify the sprocket cover to make this fit, it take 1 minute with a grinder and cutting wheel and you can't see it from outside..very descret cut.

Pretty sure you need a new chain (of different specification) if you are using a 16T front sprocket too, for those thinking about it.

Nah, same chain will work, but you'll find yourself moving the wheel in closer shortening your wheelbase by a little bit. But that makes for faster turning! :)
