Guzzi had an alternate top plate for the triple tree that kicked the bottom
of the forks out to reduce trail. This makes the steering much lighter which
is a great help with a side car rig. Same idea as with the BMW/2 earles fork
models. Only draw back is that it makes the bike tend to go into a wobble
when the side car is removed. Local dealer had one that he crashed on a test
ride as it hit a pot hole and went into a wobble. I have the upper triple
clamp from that bike and as I recall there is about 1/8" to 3/16" difference
in the position of the holes for the tubes. The top of the fork tubes are
pulled back which changes the rake and trail. It lengthens the wheelbase by
about 1/2 inch. Makes for much lighter steering on a sidecar rig.

| Subject: Newby....wheelbase/wobbles Hi, my name's Barry. I'm considering buying a 1970, ex LAPD Ambo 750, and I'm told it has a longer wheelbase than most,thanks to its non standard triple tree/fork angle, which gives more rake to the forks, and makes it more suited to hauling the sidecar it's attached to. My question: what's the standand wheelbase of this model, and can anyone confirm that this triple tree/long wheelbase was infact an option. I read with interest some posts to this list re speed wobbles, how common a problem is it? I have heard that the early /5 BMW's from the seventies had wobble woes, so they brought out a the long frame version. Did Guzzi do the same with the " Loopys "? Thanks alot, Barry Swanson, New Zealand. |
