Did a search and couldnt find anything.
What is the max speed for 1st? 2nd? 3rd?, etc

I ran out of road but here's what I came up with.
ZG1400 getting opened up a bit

Sorta like this. (I don't think many will get that reference)

I think it's:

1st

2nd

Yea, though I walk through the valley of the shadow of death, I will fear no evil:

Since 6th gear is an overdrive (hence the OD in the display) it is purely there to reduce engine rpm at cruising speeds.
Overdrives have a small effect on fuel economy but it's mostly about reducing wear on the motor/gearbox.
Fuel economy is almost all down to drag once yer running at constant speeds.
Higher speed = higher drag.

Someone on here did a speed run on an airfield a few years back (on a faster 1st Gen,.. naturally! ) and clocked 176Mph with no side bags and OEM screen, but I can't remember if he'd removed the 'Flies and fitted a Power Commander.
That was in 5th gear.

My personal record was 165Mph indicated (in 5th, probably about 155Mph real) on the Autobahn (A3, Frankfurt to Bonn) whilst "playing" with a guy on a ZX12R. We had some fun!

6th gear is NOT an overdrive, the display is lying to you. The gear ratios for the C14 are :

1st 3.333 (50/15)
2nd 2.412 (41/17)
3rd 1.900 (38/20)
4th 1.545 (34/22)
5th 1.292 (31/24)
6th 1.074 (29/27)

To be an overdrive, 6th would have to be 0.99 or less.

Actually there are several definitions as to what OD stands for on the C14, but OverDrive is not one of them.

Being that I rarely use it under 70/75 mph, I would consider it for sure an OD.

"Over drive" is now a mostly confused/lost term. Traditionally it was an addon gear ratio box that could be added on top of any gear. That is long gone.

I do like the Wikipedia version of the current use: "an overall gear ratio between engine and wheels, such that the car is now over-geared and can no longer reach its potential top speed". In that regard, 6th on the Concours really is an overdrive.

- don't like the "OD" display on the dash , would much have preferred just "6"

- "OD" is so old school.

Why isn't it an overdrive? I'm sure that OD doesn't stand for overdose in the manuals. Kwak considers it an overdrive. Just wondering...

the ratio itself is irrelevant. A car could even have 2 or 3 OverDrive, if desired. Those extra gears are not for reaching a higher speed, but to lower the RPM when cruising, hence reducing wear and improving fuel economy. I seem to remember driving a BMW 650i with that new ZF gearbox with 8 ratios, and 7th and 8th were overdrives. Or it might have been only 8th, don't know.

Is this question in jest?

We're talking about transmission gears and transmission gear ratios. The primary purpose of the transmission is to change it's input shaft speed relative to it's output shaft speed. That doesn't include the engine power available, the final drive ratio, or the wheel & tire diameter in the gear ratio equation.

If the transmission input speed is greater than the transmission output speed, the gear is a under-drive.
If the transmission input speed is equal to the transmission output speed, the gear is a direct-drive.
If the transmission input speed is less than the transmission output speed, the gear is a over-drive.

The Wikipedia description is weak at best. Saying the term overdrive is dependent on the power output of the engine, and what it can do at the wheels, is not based on anything tangible. Put a 20' sail on the front of the bike, and second gear becomes an overdrive in a head wind. With the proper tail wind, there would be no overdrive at all.

I fault Kwak for not using proper terminology with their gear selection display (Marketing spec'd, I'm sure). Heck, they probably authored the Wikipedia entry as dis-information to cover their marketing jive ("OD").

No. Totally serious. Do you have a link to something or can refer to a book that has the 'proper' definition of overdrive? I'm willing to listen to alternate theories but I need solid references before I change my mind. So far, I haven't seen them.

same here. I don't mind learning, I just need more than your word. With all due respect.

The "OD" might mean oh damn, which means you are probably on the super slab.

This link http://www.bing.com/Dictionary/search?q=define+overdrive&qpvt=definition+of+overdrive&FORM=DTPDIA says that one of the difinitions of "overdrive" is:

"highest engine gear: the highest gear in the engine of a motor vehicle that is used at high speeds for fuel economy and to save engine wear"

This fits the Kawasaki designation for sixth gear on the Concours.

But, the Mirriam-Webster dictionary at http://www.merriam-webster.com/dictionary/overdrive says:

"an automotive transmission gear that transmits to the drive shaft a speed greater than engine speed"

This does not fit the Kawasaki designation for sixth gear on the Concours.

Thanks, Wally. So it's really personal opinion on which one you subscribe to. In the 2008 C14 Design Factoid from Kwak which every C14 owner should read:

Q: Why is sixth gear called Overdrive?

A: The C14 has an extra-tall “Overdrive” sixth gear that lets the engine run
slower when cruising, producing less vibration and noise thus raising comfort
levels and lowering fuel consumption – by approximately five percent. It also
permits for a closer gear ratio from 1st to 5th for better sport performance.

http://www.kawasaki.com/Content/pdfs/products/concours_QandA.pdf

So, if it's good enough for Kwak, it's good enough for me. I'm going to still call it an overdrive (OD) but that's me. Whomever is welcome to call it anything they want or not. It's all good......I think.

If I win the race it was in 6th. If I lose it's because it was in overdrive.
