1/4 mile times?

Anyone know an official 1/4 mile time for the K1200S. Just wondering what it is.

Re: 1/4 mile times?

I just read a MCN article showing a 11.19 with 128 mph 1/4mile. 172mph top speed. That 1/4 mile time seems a bit slow for the K12S, but it is the first real article I have read.

Re: 1/4 mile times?

According to Solomoto 2/8/05, 0-400 m (0.248 mi) in 9.9 seconds.

Re: 1/4 mile times?

Ok now that is more like it...although...9.9 and 11.1 is a big difference. I would think that the bike can easily be in the mid 10's...which is fast enough fro me.

Re: 1/4 mile times?

9.9 would be "headlines" in the bike community..... Sounds very, very optomistic to me ...

Look forward to a major, recognized source with experienced pilot performing the test -

IMHO, this thing is a high "10s" at best....Though on the flip guess here, it's a very easy bike to launch due to long wheel base & does not wheelie hard - rather it stays somewhat planted at critical launch time - Why for example, the Busa (similar long wheel base) does so well....

Re: 1/4 mile times?

Vic,

Since the bike has ESA...they should do 1/4 mile runs with all the settings. My guess is that the Sport mode with the the 2 up/helmet showing would probably net the best time due to the preload and stiffness. I wonder if anyone will take this into account?

BTW you are right about the 9.9 time. It would be BIG front page news on every magazine for sure:
"Bimmer's 9 sec Beast"
"9 sec BMW...WTF?"
"Great Gadsen takes a BMW into the 9's....Yes the 9's!"

This guy Gadsen took a stock motor 2005 R6 to 9.93 @135mph in the most recent Cycle World. The only mods they did were to slam the bike to the ground and change a sprocket. Just for shits and giggles, I would really like to see him on a K1200S.

Re: 1/4 mile times?

of course......
there ain't no sprocket change on the "S"
that's where it get difficult to milk a better time out of the bike

but....
with that HP
and the TORQUE
and the long wheelbase...
"short" on power and "long" on weight
it should still yield mid 10's in the "right" hands

until the day that bmw takes the electronic management of the bike ONE STEP FURTHER and puts in TRACTION CONTROL !!!!!!!!!

Re: 1/4 mile times?

There is a nice report in Inmoto may 2005 magazine comparing the k12s to hayabusa, honda cbr 1100xx, suzuki gsx 1300.

k12s top speed 272kmh, hayabusa 285, kawasaki 303, suzuki 302.1

Accaleration
0-400 meters for K12 in 10.8, H 10.5, Kawa 10.3, S 10,4 seconds
0-1000 meters for k12 in 19.7, H 19.8, kawa 18.5, S 19.1 seconds

0-100 kmh in 3.2 for k12, H 2.8, kawa 3.2, suzuki 3.3

They conducted a good head to head and gave some good points for the K12s and others. They mentioned that the K is a strong valid bike.

They also road the bike from germany and took on a track in Italy and did 318 turns nonstop except for gas at a constant speed of 240 kmh without any mechanical problems. They opened up the engine after a total of 7k miles ther were no problems with the engine or the cam shafts..

I cant ride the whole report. But if you guys have specific questions, please let me know.

Ciao,
Shawn

Re: 1/4 mile times?

the K12R could get very close to the 9's (or for sure faster than the S) due to different gearing...which would make it more appropriate for ET's

A naked bike with less HP??

You sure about that??

the bike has less HP, but

the "R" will have less HP
about 3 - 5 less per the reports i've seen
but the lowered gearing will allow the bike to get off the line quicker....
..... if you can keep the front wheel down, that is

1/4 mile times - What do you consider "major, recongized source"

Solomoto Magazine is the largest circulation bike magazine in the Spanish speaking world . I would consider them a "major, recognized source" and very serious in their approach to testing. It doesn't mean they do everything right, but I would not discount them and their results just because they are not an English based bike rag.

The articel referred to (8 feb 2005) does a comparison between a Yamaha R1 and the K1200S. They focused on braking and handling.

They used two riders - their in house test pilot and a regional professional racer who races a modified R1 in Spain.

Braking test were based on bringing the bikes to a full stop from 80kmh (50 mph). Results were as follows:

K1200S best distance17.8 metres
R1 best distance 21.0 metres

The handling test was really more of a "flickability" test. They set up 10 cones each spaced 4 metres apart. They wanted to see how quickly they could get the bikes through the course. Given the distance between the cones this would require a fairly nimble (short wheel base) bike to get through quickly. Results were as follows:

K1200S best time 8.20 seconds
R1 best time 8.01 seconds

As for the speed ratings, the article provides the following information:

0-100 m K12S 4.3 seconds - R1 4.7 seconds
0-200 m K12S 6.5 seconds - R1 6.7 seconds
0-400 m K12S 9.9 seconds - R1 10.2 seconds
0-1000 m K12S 18.7 seconds - R1 18.5 seconds
0-100 km/h K12S 2.7 seconds - R1 2.9 seconds
0-150 kh/h K12S 4.2 seconds - R1 4.8 seconds

It does not specify how these were obtained; whether they formed part of their test or if they came from other sources.

Re: the bike has less HP, but

Actually, it appears the gearing ( at least tranny ) is same as "S" - check out the marketing data .PDF in the "R" forum....

Re: 1/4 mile times - What do you consider "major, recongized source"

400 meters is 1311.45 feet to be exact, and a 1/4 mile is 1320. So a 9.9 is not impossible, because it is less than a true 1/4 mile.

As I have learned in my youth (geez I'm only 30)...1/4 mile times have an inverse relation to drivetrain damage. You have to be willing to really abuse the drive train to obtain that lower time. In my style of riding and driving, I do more 5mph roll ons or 2nd gear roll ons...to avoid longterm drivetrain failure. I just like seeing what a bike is capable of, even though I would probably never approach those times.

Did they mention what the Density Altitude was during the test? Are those numbers "normalized" for a "standard day"?

Most of my hard acceleration is of the roll on variety for similar reasons: limit abuse of the drive train.

The magazine does not specify these details, but considering they are based in Barcelona, it is likely that the tests were done at sea level.

Re: 1/4 mile times - What do you consider "major, recongized source"

Altitude, relative humidity, barometric pressure, and temp all play a big role. Here's a good link to see how big a diff it can make.

http://www.smokemup.com/auto_math/corr_dew_point.php

This is good to see how "density altitude" (all the above factored into a virtual altitude) can affect horsepower as well....

http://www.csgnetwork.com/relativehpcalc.html

Always good to keep these things in mind when hearing about times.
