162 mph indicated on mine... throttle was wide open but she ran out of breath and just coudn't go anymore.

 

Well cbr_racin123 is totally CORRECT!

Read it and weep:

Top speed is 157 MPH on a 2001

I've had mine to 171 mph with a air filter and slip-on. In a recent bike mag there is a way to calculate your top speed through rough numbers from your manual or your own research. It calculated 170 mph for the f4i's but get nuts or grow some we all know bikes these days are just juiced for speed.

 

i'm curious... is there any diff in performance comparing the 01 F4i up to 06 F4i??

 

They're pretty much all the same except for the addition of the banana seat in 2004 & the different color choices

Don't ask me why, but I've read everywhere that the 2001 F4i was the fastest of the bunch

It was the first year for the fuel injection and then they were "detuned" for the following years

I don't really think there is anyway to confirm it or prove it....it's just what I've heard & read

 

Well wait actually....

I read that they detuned the bike when the RR came out so they could separate them more for marketing (power wise) instead of selling the same motor in a different shell

Cuz the RR is supposed to be the racey version & fast

 

i have also heard this. my friend who works at the local honda shop told me that they are all the same. honda exagerated the horsepower numbers on the 2001 model because it was new that year and wanted it to look impressive. they then lowered the advertised hp ratings on 2002 models because they knew that the totally new 600rr was going to be released in 2003 and they wanted the 600rr to seem leaps and bounds better than the f4i. just one guy's explanation but it seems to make since to me.

 

well there ya go....that makes sense too!

Either way....the 2001-2006's all have the same engine

 

So on that clip of that guy topping out his F4i, was he tightening his steering damper before taking off? If so, for top end speed, is that a big safety precaution?
