I think they had sidecar tripple trees with more trail built in, which
might make an infinitesimal difference in wheelbase.

 Barry,

My experience with the "wobble" has lead me to believe that the wobble
is
primarily caused by a loose swing arm. Of course there are other
factors to
consider like the steering head bearings, tire pressure, loose shock
mounts
etc but any wobble I have experience (on a few bikes now) has been
cured by
fixing a loose swing arm.

As for the wheel base, I don't know of a modified version of the
police bike
having a longer wheel base....maybe Greg Field would have a better
idea.
 From the manual V700 had a 56.9" wheelbase, the 750 had a 57.8" and
the 850
is stated as a 58.8" wheelbase. It should be noted that the manual
states
includes the word "about" in those dimensions :-)

Hope this helps...Ian

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.
