Putting 2 front wheels on a motorcycle - Page 18

You won't have to re-title your motorcycle as long as you leave the
steering head
intact and leave whatever stickers are in that area intact.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I was really hoping to use all the front end components of a 2 wheel
drive, 4-wheeled ATV.

Trying to salvage the the steering head knuckle of the donor bike would
be problematic.

====================================

But you don't need to use the steering head at all. Just clamping a
straight axle between the two front wheels won't work because you won't
have Ackerman steering where the inside front wheel turns tighter than
the outside front wheel

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I considered using the front-end of a pro-class go-cart, they're
surprisingly sturdy and might do the trick. (it would have a nice
low-center of gravity too)

Unfortunately it would be nearly as simple as putting a whole different
front-end, with all the suspension and steering components already to
go. (using an ATV's would mean just attaching the throttle and clutch
cables, after welding the front-end + motorcycle together)

=====================================

If I was doing this to a regular motorcycle, I would shop around for a
Renault Alliance front end and weld some adapter to the motorcycle frame
so it would bolt up.

Google that "Sport Renault" and "Spec Racer" and find out what wheels
and tires are available.

The Renault Alliance became the basis for an SCCA sports racer class
that was once called "Sport Renault". The class was called "Spec Racer"
when Alliance engines became rare and they went to Ford engines.

It used a Renault Alliance front end in front, and another one in the
rear, with a
cross rod that kept the rear king pins from pivoting

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I probably look for a Mustang II front-end, (the kind used for many kit
cars) or something light and simple like on the front-end of a dragster.

It wouldn't matter if the steering head was bent a little, it wouldn't
take any chassis loads, you would just it for attaching the steering.

But, whatever condition it was in, you would want to keep the steering
head because it has the VIN number stamped into it.

You would never take the modified vehicle to the DMV, you would just
want the numbers in case you got stopped and some officious highway
patrolman
wanted to check them.


Problem with small diameter tires is that ride quality would suffer.
The little
tires would vibrate like crazy in response to rough pavement surfaces,
not matter how finally the wheels were balanced.

You'd get front end washout at a rather low speed. Go kart racers
don't mind having their kart slide around, but it would definitely
bother *you* on your three wheeler.

If I built a three wheeler, the front tires would be at least 18
inches in diameter, but 24 inch diameter tires would give a better
ride, similar to what
a motorcycle already has.


Whatever you can easily bolt up to some longitudinal frame rails would
work
fine. Just don't forget that your frame rails will lozenge (twist)
when weight is transferred between the wheels and design proper anti-
lozenging bulkheads
with diagonal or X cross members.

Seems to me that the simplest approach would be to find a dead Type 1
Beetle and pull the front end, then rig a bracket for it.

Nice thing about that approach is that the front end comes off the
Beetle with (IIRC) 6 bolts with the shocks and shock towers and wheels
and everything else still attached, and there are well established
procedures for adjusting the spring rates and the like.

The hard part is finding a dead Type I in this day and age.

'74-'80 Pinto front suspension uses the same parts as the '74-'78 Mustang
II, and there are a lot more of them.

Any light, small, basic car front-end should
do, if I went that route.

Using an ATV front-end has the advantages
of being more akin to the designation. (that
being registered/Titled as a motorcycle)

I'd even look for one of the same make and year.

I'm willing to bet that building something which would require getting
it certified by DMV would not be easy or cheap. (to certify)
