OBD-II connector?

I know this was supposed to be a standard feature on cars after what, 1995 or something? But do motorcycles have anything like this?

I ask because I came across this digital instrument panel gadget that I think would be very useful as it combines a number of other small gadgets I've seen.

The only trouble spot I can think of if there is an OBD-II diagnostic connection on a 2000 ST1100-ABS is finding some way to weather proof it - but first I need to know if it's even capable of being hooked up and I thought I'd check here. There is a compatibility list under the 'details/specs' tab at the top of the page but it only lists automobiles.
 
I would highly doubt it. I know the requirement has been there since 1995 as you mentined in cars and trucks but that was a requirement to make all manufacturers use a standard format so that generic readers could be used. This was to keep them from making people go to the dealer for maintenance and to help smaller shops because otherwise they would have to buy an expensive computer reader for each brand of vehicle that they wanted to work on.

The reason I don't think there is anything like this on the 1100 is because as far as I know there is no computer that takes all readings and then adjusts things like timing and fuel flow. Thsi is because they are all your basic carberated systems. Now the ABS model does have some form of computer to tell it to activate the ABS and TCS but I would doubt that it has a OBD-II type diagnostic port. It would be more likely to find on the ST1300 being that it is a FI system and it uses a computer to monitor systems but I don't recall reading about one on that bike either but it may be there.
 
There is no OBD II (or OBD I for that matter) connector on any motorcycle AFAIK. This is an EPA/cage requirement only. There are of course diagnostic connectors on some bikes, the ST13 has one, but these are manufacturer specific and proprietary.
 
The 1100 definitely doesn't have any sort of diagnostic connector. The 1300 does, I think, but I have no idea if it is ODB-II compliant. I kind of doubt it.

The impetus for standardized ODB and ODB-II btw, had little to do with helping out independent shops or giving owners more flexibility for service. It was a mandate of the Feds for emissions control purposes, first and formost.

I guess that is true. Since when does the Government give a crap about a small business. I guess it is a great side effect.

Edit: I guess as more proof. I have an OBD-II reader and bought the expansion pack so that I could read all the data for GM vehicles. While I can read basic data from any OBD-II vehicle and clear codes, if it is a GM I can pull much more detailed reports and real time data. I know that there are some areas that are still manufacturer specific in the OBD-II system but for the most part all the trouble codes can be read by any generic reader.

The ST1300 has a diagnostic connector, but it is not OBD-II . It is Honda specific code and it takes their hardware and software to read. It can be purchased at Helm Publication ( which makes the OEM manual), very expensive.In the near future, motorcycles will have to go to the CAN system.

Getting back to the digital instrument panel that was posted. Keep in mind that the Speedo on the 1100 is mechanical so even if there was a computer that wouldn't be monitored. Now that said he did say that he has an ABS model and I know that has a secondary wheel speed sensor that could be possibly used as a VSS pickup but most likely not for this gauge. It would take too much tweaking to get it to work. I guess another question would be has anyone tried to tie into the wheel speed sensor for the ABS system to pull speed info for an electronic cruise control? I don't have an ABS so I don't know if the computer just looks for a difference in rate of the pulses or if it actually monitors the actual speed each wheel to determine when to enable the ABS. My guess would be that it just watches the pulses and if the two exceed a variance of a certain % then it activates ABS.

And what is the 'CAN' system?

This is from Wikipedia

"ISO 15765 CAN (250 kbit/s or 500 kbit/s). The CAN protocol is a popular standard outside of the US automotive industry and is making significant in-roads into the OBD-II market share. By 2008, all vehicles sold in the US will be required to implement CAN, thus eliminating the ambiguity of the existing five signalling protocols. "

OBD-II
