ok I've had a look on http://www.gearingcommander.com and not sure what to do ![Anxious](https://katriders.com/core/images/smilies/eusa_shifty.gif)
First up I have a Katana GSXF750 2006 model. I live in Australia so speedo is in kmh
I want to lower my rpm from around 5000rpm to around 4000rpm at 110kmh and I would like to know if changing the sprocket size will affect the speedo![Question](https://katriders.com/core/images/smilies/icon_question.gif)
I was thinking of going a front 16t and a rear 42t what do you think![Question](https://katriders.com/core/images/smilies/icon_question.gif)
Anyone got any ideas what I should do![Question](https://katriders.com/core/images/smilies/icon_question.gif)
TIA
