Topic: euro spec 750's Q?s

[Don R]

   I ordered  K1 handlebars from DSS (might not have been on the us spec list)  and got the lower Euro handlebars. I like them, but that got me thinking. I had read the K2 continued in Europe while the US got the K3 through K6. Is that true?
  If so,did the Euro spec bike continue with K2 paint, Headlight ears, headlight bucket black or painted? Handlebars and controls, etc?  I know the winkers were different than the US bikes. Just curious. How about down under, or other parts of the world?
  Just curious.

Hi Don,
We definitely continued with the K2 from '72 thru '76 in Australia. W didn't get a K3/K4/K5. The K6 arrived in Australia in '76. I think our K2 was similar to what was supplied to Europe. We were also supplied with the lower style bars. As far as I know the K2 fork ears were chrome & headlight bucket was black. The blinkers remained the same (K2 style) throughout for the entire K series.

Be aware that you will need slightly shorter clutch & throttle cables for the Euro style bars.

I think that Sweden got K0, K1, K2. No K3-K5
K6 from 1976, many of them 1977 in the registration

[MikeSimon]

Yes, that's correct. "Rest of the world" outside the U.S. jumped from K2 to K'76

 On a sort of related note, I see that some Euro 500/550's have a grab handle instead of the rail or bar. I'd like to see how the turn signals mount.
 I also always sorta liked the German(?) roundish/oval-ish tail light on some models.

No K3-K5

We didn't have them.

Scott, it varied from country to country so you must know the 'area code'. Did you have a look at the various parts lists? Some show it very well. http://www.honda4fun.com/materiale-documentazione-tecnica/parts-list/parts-list-cb500 and http://www.honda4fun.com/materiale-documentazione-tecnica/parts-list/parts-list-cb550

That particular taillight was usually seen on old agricultural tractors. That's why we didn't think it was very classy. But Strynboen is very happy with them, on his bikes and his tractors.

 I'd bet the bikes with the grab handle used a K0 style rear turn signal mount. The tractor light info is funny, as is our reliance on only sealed beam headlight bulbs for so many years in the US. Hence, no front parking light on our bikes.

 I would think the K2 tank paint would have been updated to the newer style just for ease of production.

 I've looked through several parts fiches and can't find the grab bar. They all show the wrap around rail like we got here in the U.S.
 I wonder how the early CB750 grab bar would fit the 550 frame? Or the ones listed for the DOHC 750 and 900?

I've looked through several parts fiches and can't find the grab bar

Just one look in one of the CB500 Parts Lists and I found it.
It's in p.86 http://www.honda4fun.com/pdf_parts_list/pdf_spac500/CB500-71/CB500-71_3.pdf
Partnumber of that GRIP, SIDE is 50316-300-030 and that part was also on the CB750K (A) and the CB750K1 (A).

[Scott S]

 That same parts fiche link you posted doesn't list the turn signals. How did the rear signals mount when the grab bar wasn't used?

[Deltarider]

I never give links to fiches, only to the original parts lists, IMO the only way to have the overview. So if you had gone through the rest of the Parts List, I'm sure you would have found what you looked for. Sorry, but I'm not going to do for a second time what you can do yourself.

[Scott S]

 Sorry....parts LIST. I looked through the lists/fiche on both. They show the signals mounted to the U.S. style grab rail. I looked. Not asking you to do anything for me. Just thought since you're on the same continent where that style bar and signal mount was used, maybe you could share with us in the New World. Sorry to inconvenience you.

 Thanks. I see the mounts now but can't read the part #'s. Doh!

For a higher resolution consult one of the other CB500 Parts Lists. They're ALL here: http://www.honda4fun.com/materiale-documentazione-tecnica/parts-list/parts-list-cb500

The CMSNL site has all the bikes by year/model and country. As far as I know it's correct. I think first year 500 had small grab handle on left side, other two year 500s had full wrap-around bars. Similar scenario for 750s. I know the small grab is interchangeable on the 750s with the full wrap-around, I assume 500 is too.

For whatever reason, the fiches on CMSNL don't show the small grab, but it's this:
http://www.davidsilverspares.com/CB500K0-FOUR-1971/part_4406/

50316-300-030

If you're converting you can buy the stock style mounting hardware for stock lights, but it's expensive. Cheaper to mount up some aftermarket signals. But you can still get most all the stock parts for the correct light install.

Start here for CMSNL by model:

And there are some posts here regarding stock cables for Euro spec K2 bars on 750. I went with that I love it. Only thing not available is upper brake hose, but I ordered stainless anyway and had it made the length needed.

The 750 K1/K2 factory euro bars are the real deal, PN: 53100-300-610 and they have been discontinued. I have used those repop DSS bars PN: 53100-300-610P in the past and found them to be identical to my original 750 K1/K2 euro bars. If it’s important to you, they have the correct dimensions, knurls, switch pin holes and wiring cutouts that the cheap copies are usually missing. These are their dimensions:

Width: 29.50” or 748 mm
Center: 4.90” or 125 mm
Rise: 2.99” or 76 mm
Pullback: 3.81” or 97 mm

If you are fussy about a factory correct fit and look, these are the 750 K1/K2 euro bar part numbers that Honda used as they are shorter than their USA K1/K2 counterparts using stock bars:

-Clutch cable (22870-341-610) superseded to: 22870-426-610
-Throttle cable “A” 17910-341-611
-Throttle cable “B” 17920-341-611 
-Brake hose “B” (45126-300-611) superseded to: 45126-300-612

 * These part numbers are not found in the American Honda parts system, I purchased mine from DSS (UK)

* The upper brake hose “B” is longer available and will have to be located or made, the total length needed is 12-1/2”

Thanks Chachi that's some good info and saves a lot of research. I'm not sure if it's original, my K2 has the tall bars like K3 and up, the K1 has a shorter bar already, I'm hoping the cables will be OK and I think it needs new brake lines anyway.
