1. Husqvarna Motorcycles Made In Sweden - About 1988 and older

Any of you old timers know the mid 80's triple clamps offset off the top of your head

    Just kidding, I'm an old timer now too, I guess. Only notice when I look in the mirror, or move lol. But yeah, this is my first Husky, and I'm gearing up to try and adapt the 98 RM Showa 49mm TC forks. I'll be taking big time precise measurements of all things important of the stock 40mm Swede front end, before then comparing to the Showa's. Just as I've been giving it more thought though, and looking into it, I'm seeing some interesting numbers when looking at other triples, and then what some team riders tend to like on other makes, etc.

    I'm planning to eventually, really have this big Husky dialed, in all areas.

    Right now, I'm just about to start the measuring, but I'm wondering already, if I'm going to need to get my hands on some other triples or not.

    Just some cursory stuff I found in a little googling, and note taking.

    These 49mm Showas were rated as 11.4" of travel. So a gain of .2".

    The stock RM triples, supposedly are a 24.5mm offset (stem centerline, to fork tube forward offset / centerline).

    DRZ, read are actually 18mm, which is tight. Perhaps if that's accurate, it's for the woods riding :excuseme:

    Saw reference to the KTM 50mm WP conventionals as being 14mm from one source, then 16mm from another. Now that's real tight.

    Some RM triples available with a 21.5mm OS, but hard to find supposedly.

    Then spotted some reference to Kawi factory team riders tending to like a 22mm OS.

    Just interesting food for thought. Will be real curious to see how things actually measure out, and what triples I do in fact wind up being able to use.

    Goal is to not hurt the strait line stability, but if at all possible, try to gain some turn in ability in the big Swede. Will be fun, regardless.

    Oh, and as I've been continueing to look into the forks, I actually have spotted some more fellas that actually prefer these Showa 49mm TC conventionals over all other forks, including the WP 50's for various off-road outdoors riding. Plush plush plush continues to be the word on the TC Showa's, can't wait

    Sure would appreciate though, if anybody knows the Husky factory triple offset for the 85 to 87's. Noticed in some of the bulletins, reference to custom tighter triples, but no numbers given as to what guys were going with.

    To address the issue of the title, the clamps for the 40 mm forks I have seem to have two different offsets. The ones with the rubber handlebar mounts are more straight across than the other ones which are more triangular. Both are mid eighties and I sure haven't had every model from the mid eighties to inspect.

    You seem to be jumping around and not looking at what the larger picture is. Generally rake and trail are the things listed in spec sheets. The offset of the clamp and the offset of the axle to the center of the fork have to be added together without doing this and listing a bunch of offsets and manufacturers kind of leads to the garbage in garbage out type of result. I am not sure if any dirt bikes have the triple clamps so that the forks are not parallel to the steering stem, I have a British twin which is this way.

    As for the ktm stuff you post above, for 2004 200 or really 193cc model the exc came with 20mm offset and sx came with 14 with similar forks for geometry purposes. Some models later had adjustable clamps. Are you sure the conventional 50 mm forks aren't marzoki or some similar spelling magnum instead of WP?

    As someone who had done a bunch of mix and match of triple clamps and frames you have bearings, seals, and stops as the general issues. If you are unfortunate you get into the length of the stem.

    So it seems I need to also quickly take note of the axle centerline to fork centerline, when then stacked with the triple offset. I realized it was that total that gave the important numbers. However, with so much specific discussion on the net of simply the triple offset, guess I thought I'd focus there too, at first.


    Thanks much for the info.
