How does the 15T front sprocket do at 60-70?

[Focer]

I was thinking about droping my front sprocket to a 15 but, I just want to make sure that I could still cruze at 60-70 on the freeway, without the rev.s getting too high.

60 is 100 km/h?
70 is 120?

if so than with 120 you'll be doing 6000 rpm with a warmed up engine
i have 15 tooth for more than a year its one of the best mods for the gs and its cheap, i also sometimes use 14 tooth just for town    :mrgreen:
my topspeed went up whan i started using the 15 t, i expected it to go down but it went up

i'd want to know how it does in the 85-100mph range...  that's more along where I cruise at. 60-70 would get you rear-ended hard around here.

140 km/h is 7000 rpm and about 160 i don't really know, never payed attention on that

i almost always ride 140 - 7000 in 6 and after a while u get used to that
a drawback is higher fuel consumption and maybe higher oil usage (higher rpm spits out more)

just got the 15 tooth.
install tomorow...
oil change, full synth also.(9k on gsf so far)
now i just gotta get my springs installed... 80 bucks a hour for suzuki to install......

roughley my measurement with the 15t front sprocket is
5k-60mph
6k-70mph
7k-80mph ect.
This a rough guess As I dont have a working speedo right now.
And yes my top speed went WAY up when I droped the sprocket.
Had my buddy pace me at 120mph, according to his speedo.

I got 76 mpg on a trip from Seattle to Portland with a 15t front...also have k&n pods, jetted to 150, stock pilots, and wileyco can.
