who knows the top speed??

i am 17 and want a 2005 yzf R6 or a 2004 cbr600rr when i get into the navy and i would like to know about how fast they are. so any ideas about the top speed???  

Off the top of my head, I'd say close to 150 (could be wrong)

Wouldn't recommend you test it on public streets though.  

I used to have a 2005 r6. i got it up to around 160. not sure how much it had left to go due to the lack of straight road.  

Do you remember what rpm you were turning at 160?

and are you talking about 160 indicated or actual  

Cant quite remember the rpm's i would say around 15000. i remember shift light was on and the last numbers i read were 158.    

Nice, was this during the day ? Howd the bike feel at that speed?

All the times I have "maxed out" my bike I love how it felt super stable and planted, unlike many cars I've been in.  

Pretty much most 600 are going to be about the same in top speed, I own a '06 ZZR600, which is very similar to the F4i and I toped out at 168. my friend own a new Gixxer 600 and did 175, but that would be absolute max for any 600.  

I have an 01 R6 with -1 front sprocket and topped out at 180mph! I was at redline-15,500rpm and in a full race tuck.
I also ran the 1/4 mile in 10.75@129mph.
Go with the YAMAHA!!!
                 

10.75 is a good time.

You can probably break into the 9's with more practice.  

Agreed, go Yamaha =P I have an 02 R6 and I changed out the chain/sprocket to the Vortex 520 conversion. I know my top speed was compromised a bit, but it more then makes up for it with the added torque and increase in low end power. Besides, why should you be going more then 100+ mph on the street?  

My friend has the 2005 r6, he claims he hit 176 on his. I have the 2007 r6 and my spedo said i was going 167, i was around 1600 rpm.  

I had an 03 R6, went 176 with a few mods. Good luck... i would go with the yamaha!!!  

r these stock bikes you guys are talking about cause there is no way a 600 can run in the 170s and 180s stock  

Skydiving_sob is right. Your only gonna push 150, 160 tops. Speedos are highly inaccurate @ those speeds. You need something else to track speed.  

my bro has one and he ran bout 147 and shut it down. im bout to go to navy as well!!!
