whats the best and easiest front end swap to convert early H1 drum brake to disc
thanks

H1B onwards and any H2 should swap and bolt on. I bet someone here would straight trade a disk setup for your drum front end.

From what I've read from this board, ideally you want to use the lower tree from the H1B in order to maintain the correct (same) geometry as the 69-71 when upgrading to the disc-brake set-up. The rest of the parts - forks, axles, calipers, etc., from all other models should work fine as pointed out.

Ok thanks for the replys

so just to confirm....are we saying its the lower tree that changes the geometry and not the frame headstock .its just that its easier to find latter ones ,D,E,F than to find a B type ....thanks for your help

Darn, I just can't recall...it's been awhile since I learned of this detail in lower clamps. I hope others will chime in with a definitive answer. In the meantime I'll search around to see if I can find more information.

Update:

Here's a couple links regarding this topic:

Thanks for that info Kawi3cyl

The triples all have parallel trees. IE the forks are parallel to the steering head. It's the distance from the steering head center line to the center of the forks that is the critical for the trail.

There is a calculator on Dales site.

now the hard part,.........trying to find H1b steering parts

If you cannot locate the upper and lower trees over there (to avoid overseas shipping costs), just send me a PM - I may have both trees in my garage.
