what is yhe top speed of the 05 vs the06 and how much of a diff is the bike overall

i was told that 180 on the 05 but not sure if that's true or not i dont know about the 06 i have a 05 raven

i hit about 150 on my 06 r6. I still had a couple thousand rpm left before redline though. i would guess ~160 is the top speed, depending on rider weight.

The speedo will over-read, but 160 is about the true limit

i rode a 06 but i never toped it out.... but the low end isnt there at all

that would be thanks to an over-square motor. there are also only about two ways to truly tell how fast you are going. A) a prtable garmin GPS unit. i have once since one of my bikes does not have a speedo. if you dont know how these work, they triangulate your position between three satalites and measure the rate of movenment between them. B) is by stop watch method, like what they use at the salt flats. plus top speed is nice, but where on a track will you see that? the only time that i have seen 160 ( yes recorded on the garmin gps) was in the nevada desert on one of the longest straighest roads i have ever see, and i rode it multiple times to make sure there were no obsticals.

Yeah, to some extent Oldschool is right - there aren't a whole lot of tracks where you're going to see 6th gear at the redline, unless you're re-gearing for every track.

I run my track R6 down one tooth in the front, and the only two places I found myself hitting the limiter in 6th are on the VIR full course and Road Atlanta.

top speed is a fuction of gear ratio. you can gear a moped to go 200 mph, however it may take it 3 days to get there. horsepower is the other factor. there's a saying that goes: "there is no substitute for horsepower."
and that is true.

theoretically you can gear an r6 so it can reach maximum top speed, but why? the whole purpose of gearing is to achieve a trade off between acceleration and speed.

there is no doubt that the r6 is a purpose built motorcylce....meaning racing, but it works very well out in the real word too as a sport bike. my point is this, a stock r6 with stock gear ratio will go fast enough to make anybody happy.

if you want a little more acceleration, gear it for that, but your top end will suffer, gear it for max top speed and you wont even leave the stop light at a respectable speed. (this is where the horsepower comes in to play, you can gear a bike for max top end, and achieve decent acceleration if you have enough horsepower to compensate.)

for the guys that race, we know this too well, you can only go so fast on a certain peice of track before you will excede either your, or the bikes cornering capabilties, thats why the goal for any rider is to gear the bike so it achieves 6th gear redline on the fastest part of the track, genereally just before the first break marker. that is the goal, and isnt always possible, but getting close with out being geared too short is the point.

with proper gearing, the bikes uses all its horsepower to go as fast as the track allows at anypoint on the track. therein you have the trade off between top end and acceleration. you dont need all the speed the bike is capable of, thats why you regear it to give just what you need, and then you are able to use all that HP to accelerate out of corners.

this was a little long winded, but i hope you get the point. i could go on and on. bottom line, if you want to go 200mpg get a busa. that has the HP to accel, and get top end.

'99 was tested by MCN to 163mph. I've seen an indicated 162 - so probs true 155. had a little left but nothing worth chasing.

just not enough power there to get it much over that speed - too much drag. I even tried coating the tyres in oil to reduce friction............

You are partly right in your thinking that you could gear a bike to reach any top speed. Except you are missing one huge criteria...Drag.

Sure you could go up 2 teeth on the front sprocket and have a theoretical top speed of 202 mph, heck stock the top speed is calculated to 180.33mph, unfortunately the motorcycle doesn't make enough power to overcome the drag at that speed. This is why R6s and most 600s for that matter are "drag limited", they just don't make enough power to push all the way to redline in 6th gear.

On a bone stock r6, if you changed the front sprocket only to a 15 tooth instead of a 16t, you will change the overall topspeed from 180.33 to 169.06 mph. This is still too high for the bike to actually reach. But geared in that manner you will have a much more useable range of power. Think about a bike that now has pull in 6th all the way 15k rpms as opposed to dieing out at 13k in stock trim.

With that change in gearing you're purpose isn't a trade-off off acceleration for speed at all. It is just realligning where the speed occurs in the rev range. You haven't lost any topspeed at all. In fact you will gain topspeed becuase you will be at a higher rpm for any given speed, and along with the higher rpm the motor will be producing more power. This additional power could be enough to get 1 or 2 more mphs.
