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 The previous version was outdated and no longer supported.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

Shock specs for 1980 frame

I need to replace the shocks on the 390 I am rebuilding. The frame is from a 1980 XC390 and I am trying to find out the specs of the shocks that should be fitted.

I believe the overall length from eye to eye should be 17.25 inches but I also need to know the travel of the shock. Please could someone confirm both of these dimensions? Thanks in advance :)
 
Murph,
My 79 CR390 has 17-1/4" Ohlins (I believe they are original).
The exposed shaft length is 4-1/4" and they have a 2" bumper.
I would think this would be appropriate for your bike.
Wasn't the 390 an "OR" in 79? I think the XC's didn't show up until 81.
Hope this helps,
Ron
 
Thanks Ron. As it happens I have just been looking at the Vintage Husky website and it has a copy of the brochure for the 1980 OR390 and it is exactly the frame I have, so I think you are correct. I was told it is an XC frame but now I agree with you, it is an OR frame.

I am pretty sure the shocks on your bike will be the same ones used on the 1980 OR frame, so thank you for your help. Just one question. Is the 4-1/4 inch exposed shaft measured to the top of the bumper or is it not including the bumper at all? Thanks again.
 
The 4-1/4" did not include the 2" bumper, so the shaft would be 6-1/4"
with no bumper.
I believe most tracks consider 1/2 of the bumper thickness, as shock travel.
I agree the 80 frame is the same as the 79, except they cut the rear fender loop off on the CR's from 79 on.

Murph,

My 1980 390CR has 16-1/2" c-c to shocks, & the Husky OR brochure
i've attached says travel is 314mm or 12.4 ".

I think and I could be wrong, the OR's used Curnutt shocks that were shorter to rake out the front end a bit more.
The OR's got their changes based on input from the desert and Baja racers, like Larry Roeseler (I remember reading that somewhere).
