• 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 The previous version was outdated and no longer supported.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!

How long is it and what is the distance from the pivot to the shock mount? And are all the ML arms the same? Thanks, Ed

Looking through the parts catalogs at halls-cycle.com for my various projects, I found that the 1978 CR 250 & 390 have the same swingarm (part # 1510720-01). But the 1978 WR 250 & 390 WR, the 78 CR 125, & the 78 390 AMX have a different one - part #1510609-01. The WR one is 20 3/4 inches overall length, and the pivot to the shock mount distance on it is 14 inches. Also, the chain adjuster layouts are different on the 78 CR and WR swingarms. The 78 OR 250 had a 1510716-01 swingarm, but I don't know the dimensions on that one.
 
SwingarmComparison

Here is a picture of a 1978 CR250swingarm in comparison with a 1980
OR(same length as CR) Note that the 1980 was longer than the 79 but had the same width The 78 was narrower than both the 79 and 80 but the 79 and 80 were the same width. The 79 was the same length as the 78. 1980 was the year that the CR and OR recieved a longer swingarm for better tracking and handling... conversely it also now made the bike more stable but it was harder to turn.....

1978 vs 1980 length comparison 22.250" vs 23.250" picture is slightly misleading so Ihave listed the actual dimensions here:
