• Husqvarna Motorcycles Made In Sweden - About 1988 and older

  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Swedish Steel Used On 70's Husqvarna

I know I have read or seen somewhere before the answer to this question, but does anyone know what the Swedish SIS (Swedish Institute for Standards) number is for the steel used in Husqvarna frames made in 1970's. 4130 is the American designation of a steel that is close to it, but I really need to know the exact SIS number used. There is also a British steel that is close to it, but again only interested in the Swedish steel or, where I can find out. Thanks

I do not know the SIS #, but the steel is called Chromium Molybdenum Steel. It has a high yield strength and corrosion resistance. Good stuff.

Thanks Rojotes390CR! I am a mechanical engineer and am very well familiar with American Chromoly steel 4130 and other grades, but I really need to know the exact SIS number of Swedish steel as I plan on buying it from Sweden if necessary. Only the best Swedish steel will do for the application I am going to use it for. Thanks again for your comment to my question, much appreciated!

On another note looks like you have a 390CR just like mine, cool!

Yes Sir. I just picked this one up from the second owner for over 30 years. He did a nice job on the restoration. What year is yours?

1979 same as yours! But I have a lot of work to do on it, almost a basket case when I got it. Right now I am designing a seat pan for a 1976 250CR that I have out of carbon fiber with stainless steel brackets (or Ti6-4, already made) and SS fasteners. It will never rust out or crack like plastic does. The trick is how to design a nice system to attach the vinyl seat cover to the carbon fiber seat pan, no staples here. I will probably use stainless steel strips over the vinyl and bolted into the carbon fiber with special fasteners. I guess I do things from an long-lasting, quality, engineering (being an engineer..Lol) viewpoint rather than a "get er done" approach.

Thanks! That is a great Idea! I will email them today and see what happens. Thanks very much for the contact information. Although my dad was 1/2 Swede with his birthday being today (making me 1/4) I don't speak Swedish and hope that they can reply in English. Thanks again Vinskord!!
 
Any feedback on your inquiry? Be interesting to know.

BTW - more than 80% of Swedish people speak English - a phone call would not be a problem.
