1980 Brochure
Positives:
Very
easy to maintain. Great power and handling for this type of
machine. Good ground clearance. Easy to get replacement parts
for. Electric start is available for this engine from Goki.
Because this series of Odyssey was so popular, a ton of aftermarket performance
parts are available.
Negatives: Horrible
suspension but makes up for that in entertainment. Early
electrical system (points) can be a pain in the butt to set.
Pull start can be a dream or nightmare depending on your mood.
Sometimes the pull starter can rip your arm off.
What to Watch For: Watch for cracks in the frame just
behind the seat. I don't know if it's a defect but I've seen
three Odyssey's with cracks developing in this area. I think
its cause may be aggressive jumping. Look for
bent frame tubes and check the compression on the engine. It
should read 128 pounds. If not, there's trouble inside.
Check for spark! Up to 1980, Odysseys had a point and
condenser ignition system. Check to see if there is a good
clean spark and that all electrical connections are good and
tight. If there is no spark, it could spell trouble with
the stator and that can set you back a lot of money. Look for
a sheared or beat to death woodruff key where the flywheel is mounted. Odyssey
electrical components are hard to find and are very expensive
to purchase from Honda.

Ramjet's Ride Report
When
you hop on this machine, it's unlike any ATV you've ever ridden. You
really don't ride it, you drive it. It's extremely fast and can turn
on a dime. It will also roll onto its side if you're not careful and
control your speed and attack into a turn. I have a scar on my elbow
to remind me how wicked this machine can be.
This Odyssey has an air cooled, 250cc, single piston, 2 cycle engine
that powers an automatic
clutch/transmission system. It's a pretty flawless transmission.
There's a generous power curve to tackle the most demanding terrain.

The fiberglass body tub and fenders
do a good job of keeping mother nature off of you but you can still
take a good soaking when you blast through a mud hole and a wave of
cold water and mud wash over you from the front. That's what makes
Odyssey's such a blast. You can get into the down and dirty with the
best of them. The Odyssey has enough guts to pull you just about out
of anything you get yourself into. I buried mine up to the seat in a
swamp with other four wheelers and I was the only one to escape.
This Odyssey has an independent
front suspension with small shocks that do a moderate job of
absorbing the bumps and lumps on the trail. Where you are really
punished is on the rear end. Honda had the theory that this Odyssey
didn't need a rear suspension because of the balloon tires in the
rear would absorb the majority of the shock. Well, Honda was wrong
but I think I understand their reasoning. The pounding of the trail
is transferred right to the fillings in your teeth. Try to take a
jump and you'll bite your tongue! Sure, you can take a jump but the
landing can be quite violent and you may bounce end over end. Short
of not have reverse capabilities, it's probably on only thing about
this Odyssey that you can complain about.

There appears to be little of note
concerning mechanical changes in the Odyssey line from is debut in
late 1976 to 1980. The only way to tell a model year is from the
serial number on the rear part of the frame, a change of the color
of the Odyssey decals and the position of the headlight. In 77 the
headlight is mounted to the front bumper. In 1980, it moves to the
top roll bar and Honda adds a heat shield to the back of a more
padded seat. Also in 1980 Honda added rebound limiters to the rubber
engine mounts to keep the engine from shaking so much while running
and increased the output of the generator from 6 volt, 35 watt to
12V, 45 watt
All in all, it's a really fun
machine, easy to maintain and still plenty of parts are available. I
would hesitate to purchase another one.
