#9Does anyone make a smaller gear indicator? Acumen and Datatool seem to be a bit too bulky. Nice and small that would be easy to integrate into the dash would be nice...

#10Why do you need such?
Can't you count to six?

#11Looks nice, although I never ever look at the speedometer or anything like that when on twisty roads, an occasional look at the rev counter, and mostly I don't even use the clutch lever!!! haha I just concentrate on the road...

#14On the type of roads I frequent, the riding experience will PROBABLY be better with some way of instantly knowing what gear the bike's in without all the counting up and down.
Don't remember many hilly,twisting roads when I rode thru' Holland last summer.....each to their own I guess!!!

#15I will admit to trying to engage 7th on a couple of times today.......
But then ive always been the same

#16I don't understand the use of this either. I never count gears, why would I?...
Just keep it in the sweet spot between 4 and 9K. What difference does it make if it's in 4th or 5th or whatever? If had to count gears or watch some display I think I would crash...

#17I suspect that if KTM had fitted them as standard, integrated into the dash display, a lot of people would be raving about how handy they are! Come on - fess up!

#18I doubt it...
A f**cking more accurate fuel gauge would be a lot more useful thank you!!

#19Has anyone bought one of these
http://cgi.ebay.com.au/ws/eBayISAPI.dll ... K:MEWNX:IT
Not thinking at the time I bought it (not arrived yet) and thought it may have been a cheap copy of a Acumen but on review think is for a bike with hard-wired gear indicator ,eg lights.

#20Thats extremely cheap. How does it mount on the superduke?

#22Whats wrong with linking speed to revs/sound?

#23Bought one cheap gear indicator for my gsxr - they dont work over 150 km/h, loose programming and etc.
Post 24 by lc4,
#24Wanted to fit a indicator as when I`m just cruising along I think "what gear am I in" and have to physically check rather than taking a glance at a indicator.
Glad I did not go down the $100 plus path with the exercise going on some of the comments above.

#26I have an idea - lets design one for superduke. If some one can design the mount and case for the indicator, i can help with pcb and microcontroller programming.
Does some one knows how the gear position sensor is designed?
I know that other bikes use indicator which has different resistance for dif. gears. If we can install sensor like this then we can design very fast and accurate gear indicator.

#27Here's where I got to last time. One photo shows the internal mechanism, the other the electrical contacts.
You'll notice that the electrical contacts have a small pickup for neutral and two others for second and third (I think).
My idea was to just drill and add more contacts (because the positions are indexed - ie entirely symetrical) then
design a circuit that sorts out the electrical signal (which contact is earthed) then convert it to binary coded decimal
which is what the driver for the LED chip needs 4511 from memory (at the ex's house)
My thinking was to put everything in the headlight shell other than a 6-8 strand cable down to the gear change pickup.
A resistance based system would work I guess. Keep in mind that the wires that come out of the switch itself are redundant
for most people (often disconnected) because it's just used as a performance limiter. Thus the switch can be made to
do anything you want. The world is your oyster. You could design a PIC based system but I'd be inclined to keep it
as simple (and cheap) as possible. As you can see the display is about $US5 so I'd want the whole thing to be about $US30 max.
I bet there are people that already have the electrical stuff done. All we need is something that could plug into the
gear change sensor hole to provide 6-7 signals (neutral as well).
Of course a much simpler idea is just to have a row of leds in which one would light up for each gear. I did in fact buy a spare mask
and the LED's but got bogged down with other things.

#29So the round part is plastic and has metal contacts for neutral, first and second gear?
Yes it is plastic.
Looking closely at the photo again I think it has contacts for neutral, second and third. Looking at the second photo you'll notice that
the scrub mark starts about the seven oclock position. That's where first is. Then neutral, second, thirds Etc moving clockwise in the photo
anti-clockwise on the bike.
The contacts part is a piece of cake as long as you keep in mind that it is an earth system only.
If we can add more contacts for all gears then we can use it for the indicator driver.
Yup that's what I said. In fact, it's brilliant because it provides a very positive action.
Sometimes the pic or atmel chips are cheaper then led drivers....and you dont need additional hardware like inverters and etc.
What would you suggest? Tell me an actual device name and number? If it's a PIC can you do the program?
So there are two difficult things , first how to modify the sensor and how to integrate the led display to mask . For 05 it is not a problem, for 07 mask it can by difficult to find right place for indicator.
That's the least of the problems. Over to you for the circuitry. No rush. By Friday will be fine

#31Hi Im rushing with all the maintenance to prep my bike for the season. For the gear indicator i would use atmel avr atmega8 which has built in adc. For the software i would use bascom avr - because it is simple. So very few components - 5 volt. reg., resistors, caps, 7 seg. display and the avr ic.
