With all the R/R topics I decided to do a little research myself. I looked at my R/R today and could see a number on it. When I checked on the Internet, it seams that the Honda number is SH261-12 as printed on the unit. I can search on that number and came up with a replacement number that is 31600-MA6-601 and also 31600MS2601. I have a 1994 model and as far as I can tell that part will work on 1990-2000 years. I also found a web site that lists some other bikes that use that R/R. This will help in locating the part at the best price. For the 1990-200 R/R, look at the 13th entry on this site below.

Now for the 1987-1988 (1999 was not in the states, so it is not listed), I have not come up with a Honda part number. I would need help here. It looks like either ESR190 is the factory number or an after market number. I found that at Parts unlimited,Harley-Davidson also uses that part number. This is what the ESR190 looks like.

It would be nice to be able to cross referance to other bikes.

 

Thanks for all the effort, TBT. It would indeed be useful to have a resource which gives alternatives, in case you're stuck somewhere with a blown r/r, and a less than knowledgeable bike parts guy........
A friend of mine, who's very bright on the electrical bits came up with a jury-rig for my bike, which involved connecting a car regulator (Motorola type) into my system, as he figured the rectifier part of the r/r was fine. Worked until I was able to get a replacement from Electrex, who seem to be the only company prepared to give 12 months on road parts, and 6 months on offroad....!
I don't like jury rigged electricals, but if you're stuck.......[:-]

 

TBT,
Did you purchase it? If so, let us know if it is the correct R/R.

 

I did not purchase one yet. It is nice to know that early year ST1100s used the same R/R as the 1990 and on 1kF.

It does look like the '87 and '88 bikes had a number 3160046117 that is now 31600MA600. Search on these numbers and see what they look like.

 

Have a look at www.electrex.uk
They have a chart on their website which gives model numbers for most bikes, and you can see which models use the same r/r. Don't know about originals, other than those already supplied.
Thanks TBT for info.....

 

I had a look at a swedish parts distibutor, Duells. They list aftermarket R/R units, and their list states the same bikes who uses the same R/R as TimBucTwos link. Just a little note: Would you like to know what the price is? 1680 SEK, this is 265$!!! Those in TimBucTwos link costs 80$! [&o]

 

Typical for Sweden...poor exchange rate makes things cost plenty $$$$$$ [:@]

 

There's a very informative thread on R/R here: Cane is in pain In short it says: don't replace with Honda's original R/R, but another, like the one from Yamaha R1 for example. More info here "How to tell if your R/R is about to die" and here "Changing the Honda R/R".
Thanks to R1000 for info and linking!

 

The R/R is definitely the "weakest link" in an otherwise brilliant bike - having replaced 5 r/r's in the past 3 years I can confirm what it says in the article - thanks Cosmobob. I now have one with a HUGE heatsink, not that it will help when your stator's also cooked...........as I found out.....[sm=exactly.gif]
