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 The previous version was outdated and no longer supported.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

Frame differences.

Hello,
can someone explain the differences between the WR-CR-XC frames of the early to mid 1980s.

Where they any suspension setup differences (apart from the obvious, twin-mono shock)?

Apart from the casting and bushing difference between the H1 and H2 forks. ls there any usage/setup difference?

Thanks.
 
There were many changes in frames from 80-85 through out the different models. Some small and some big changes were made. This will end up being a large list.

Ok, to simplify. What are the handling differences between the XC-WR-CR models, due to steering head rake, suspension travel?

lm not concerned about the engineering differences, as you say would be a long list, 3 major frame differences per model in the time frame and who knows how many smaller changes.

lve just read alot about 'woods bikes' and track bikes etc etc
 
XC-CR same suspension travel but XC has WR frame with rear "hoop", extra tube under engine for protection also, makes it hard to sit on flat bike stand and different rear brake pedal/mounting, CR swingarm is different than XC as CR has floating brake and XC has swingarm stay. XC as I know is a wide ratio CR engine with external rotor. WR frames, same as XC but use shorter swingarm and shocks are back further, lower seat height. 84, up they steepened up steering head angle from 30.5 to 28.5, In my opinion they handle better. I built what I thought would be a good combo, 84 WR frame with XC suspension, including swingarm, CR jug on WR lower.

I agree. I think this is what it boils down to. Suspension travel, seat height, swingarm length, fork position in triple clamps... all can be swapped around and work great as fine tuners. But the rake changes are the largest difference by far. I looked into this pretty heavily at one point, and came up with the same numbers Mr. Fleet posted above. Also found a few references that the 83 was pulled in 0.5 degrees to 30 before the 84's went to 28.5. But that's been hard to verify. Personally, I'd like to have an 81/82 (look/colors/rear suspension/overall feel) with the 84's 28.5 degree rake. Ya, baby!
 
"Why" is a deep, philosophical question, Mr. Skidmark. Each must answer his own "why."

But apart from that, it makes a nice solid mount for a fender pack. And I think the bikes with the rear loop vibrate a bit less. Seems to tie those frame rails together solidly. And makes a nice grab handle. And looks cool.
 
Didn't a lot of enduro riders use that loop to attach a small tool bag on top of the rear mud guard?
I guess the main reason was to stabilize and take care of the extra weight on the rear mud guard equipped with tail lamp and license plate
