i got a 99' gixxer 750. i went down 1 on the front and up 2 on the rear. does anyone know how much it will throw the speedometer off ?
thanks

 

i don't have the page off the top of my head or saved, but there is a page that has all the ratios of gearing and it has a formula to tell you how far off it is. do a search for it...it's there, i wish i could help more.

if i find it i'll post it

 

thanks for the lead, i'll check it out.

 

my buddy went 1 down and 3 up on his 2001 gsxr750 and it was 9mph off.....said 69 while doing 60

 

Unlike him i remebered to bookmark it so here is the link u were looking 4
