Anyone have any experience with Croatian "Sper" regulators?

Hello, I have been looking at regulators for my bikes, and I stumbled upon a Croatian manufacturer Sper. I live in Slovenia, and the factory is actually fairly close to me. My Croatian is not that good, but their regulators cost around 50-100€, and they state they are series regulators.
How powerful is the Suzuki GS generator? I would need the regulators for an early GS850G, an early 80's GS550, and a 70's GS750. What kind of current should it be rated for?
Here is a .pdf from their site. Various regulators are listed, and also a schematic on the bottom of the first page:
http://regler.sper.hr/12V_Regleri_za_AC_generatore.pdf

I am not particularly familiar with electronics, but I figure it needs to be a 3-phase regulator.

For generators that do over 8000RPM, they only have three listed, and this one would probably be the one to use:
3 phase,
current 30A
price 92€
for 420W generators
dissipation 80W
K/W 1,2
temperature at no wind speed:+96K
Dimensions: 88mm width, 141mm length, 25mm height
Warranty 4 years for this model.

It even has it's own site:
http://www.regler.sper.hr/HVSP_flyer_all2-new.pdf


Says it automatically shuts off when temperature exceeds 70?C, and a LED light goes on when something is wrong (I don't understand Croatian that well... perhaps when the generator would generate too much energy). There is even a "Suzuki GS8550E 1983" listed as a model it can be used on, and they probably meant the GS850. There's also a "Ducati Monster 520" - yeah, riiight.


Would this be okay to use on a GS? The warranty seems fairly long to me. Also, 10% discount if you order more than one. I guess it is a small Croatian firm, a left-over from Yugoslavia (as so many other factories in this area). If I were to go there and order a bunch of them, I'd probably get an even better discount. Hopefully, it is also made a bit more robust - a small company that would make ****ty regulators couldn't exist for a long time.

Ok, this is interesting, at least for the European members in here. Judging from the PDF's, it doesn't look like they're simply reselling chinese parts.

Since there are quite a few vehicle manufactures left on the european continent, I can imagine they still get contracts there. Though, for example, on my 2014 Guzzi there is a Shindengen R/R factory-mounted - the V7's don't get above 7k rpm. My GS's are very happy with the SH775, and they easily get in the 10k range.

From my perspective, R/R technology in broad use hasn't evolved much ("keep it simple", "don't touch it if works", "good enough", yadda yadda), so it doesn't come to much surprise to me that many R/Rs are listed as fitting decades of different vehicle models.

I wonder, do the new Guzzis still use those car-like generators (without permanent magnets, with brushes...)? I guess not, if they use such regulators (I think on the older ones, you can regulate the amount of electricity by limiting the central electromagnet power?). I had a few V35's and V50's, and while they were great small bikes, you really had to open up the throttle to not get passed by everyone on the highway (I remember one time I was in some hurry to get home, and kept the 70's V35 constantly over 7000rpm, and once I got home, a few drops of oil came out the breather, but that was it).


As I understand the site, I believe they started making regulators for boats (quite a big market for them in Croatia), and the ones for motorcycles are not factory for any bike.


Hey pikl, did you ever find any joy in the BMW Airhead you were riding?
I've rode 3, a 81' R100RT modified into a CS, a 90' R100RT and a 92' R80GS. The CS and the GS were nice, but I did not like the RT. Really wobbly suspension, and they just always seemed overall poorly designed to me (high quality, but poor design - lots of things could be done better).

They look to be fine for your bike (or any except some monster new goldwing maybe) ...

HOWEVER you will have to figure where you will mount that big case.
 

..

Croatian Kuna makes it €94 ($116us) which is much more reasonable.
For some reason, the first google conversion chose Bosnian currency and seemed throw in an extra nought.
At that price, I'll seriously look at it. I could do with another one as a spare.
