==Engine==
The engine was a Liquid cooled cooled Four stroke, longitudinal 800 V-twin cylinder, camshaft nestles at the base of the V between the cylinders. ,OHV, 4 valves per cylinder operated by pushrods. The engine featured a 9.8:1 [[compression ratio]]. 
 
==Chassis==
It came with a 100/90-18 front [[tire]] and a 120/90-18 rear tire. Stopping was achieved via Single disc in the front and a Drum in the rear. The front suspension was a  39mm Air adjustable forks leading axle while the rear was equipped with a Dual shocks adjustable spring preload. The CX650 Custom was fitted with a 12.5 Liters / 3.3 US gal fuel tank.

Look! The twin that first made Honda's V-engines famous.
The Honda CX is an engine of many disguises. It was a brilliant original
piece, engineered to be the basic power block for modular motorcycles including
cruisers. Some buyers of high fashion, however, thundered right past the CX650
in 1983, beating the showroom carpet flat on their way to the Shadow corner.
Maybe they should have taken the thinking man's pause, because the cross-wise
CX is bright stuff.
The CX is a singular piece; an imitation of nothing else, this V-twin is pure
Honda engineering, designed on fresh paper and refined by the experience of a
half-dozen years in production. Who else would build a water-cooled transverse
V-twin, then close up the V-angle to 80 degrees, and skew the cylinder heads
around to tuck in the carbs and keep the engine out of the rider's way? Then
there's the matter of the clever pushrod-actuated valves from a company that
brought single- and double-overhead camshafts out of the exotic world into the
engineering mainstream.
From a distance, the CX650C has a rough-hewn look; up close, it's Honda
smooth and seamless. The shaft-drive engine package is civility manifest, and
the greatest disturbance the rider will hear is the roarty exhaust note. This CX
cruiser has a passably decent seating position (look, Ma, real bars).
Honda cleverness extended from the engineering department to the price
committee. Think of it this way: The CX650C has been on sale all year long, at
$2598. Perhaps it isn't quite as stunning a bargain as $3498 Interceptors, but
you catch the drift. In certain cases, the first price is the sale price.
Still not satisfied? Maybe you should write to Honda asking for a free
Lone-Ranger mask.

Review by Todd Quigley
As some of you may know, I own a 1983 Honda CX650 Custom. Some of you may not
remember or even care, though some of you may find it interesting. The CX650 was
the last in a short-lived run of an odd design by Honda. It started in 1978 with
the CX500, a simple and reliable motorcycle. It soon became popular among
couriers in the UK for it’s rugged reliability.
 
The CX500 however wasn’t what you would call a “normal” motorcycle. The engine
was a V-twin, not necessarily an innovative idea, but Honda decided to stick in
the bike sideways! The configuration was similar to the Moto Guzzi motorcycles,
with the cylinders sticking out on either side of the gas tank. Honda paired
that up with its shaft drive to get the power to the rear wheel. They also made
the engine water cooled, enabling it to handle a wide temperature range without
trouble. This was unlike an air cooled engine in which overheating can be a
problem if the motorcycle is not moving fast. Add in the comstar (a cross
between spoked and alloy) wheels and an electronic ignition and you had a very
low maintenance, rock-solid motorcycle. It was never a high-performer, but it
was easy to ride and maintain.
 
A few years later, Honda tried something new with it. In 1982 they added a
turbocharger. If you search around the internet, you will find reviews on that
bike. It was a masterpiece in modern engineering. However, it wasn’t quite up to
the performance Honda was looking for. So in 1983, Honda bumped the engine size
up to 674 cc’s. The new CX650 Turbo took the world by storm. It could easily
keep up with the 1,000 cc sportbikes. I’m told on good authority that there is
nothing quite like it. Honda decided that since they had this new 674 cc engine,
that they would use it in the rest of the CX line. So, along came a GL650 and
the CX650 Euro and Custom. The Turbo, GL650, and CX650 Euro had already existed
as 500 cc versions so were not changed much besides the larger engine.
 
The CX650 Custom was another thing entirely. A completely new design sharing
very little with anything that came before it (or after it for that matter). In
styling, it looked a lot like the 1983 Honda 750 Shadow and the 1983 Magna’s.
Though they looked similar, they shared almost no parts! By 1984, sales for the
CX650 series were not what Honda had hoped for. They decided to halt production.
Some say the CX650 Custom was cancelled because Honda didn’t want to compete
with itself with the 750 Shadow. But since the entire CX650 line was cut, I’m
more inclined to say they saw the low sales and dropped the entire lineup to
concentrate on the more “American” Shadow lineup.
 
Whatever the reason was, the CX650 was dead. So, if you are the kind of person
that roots for the underdog, or enjoys having something pretty unique, a CX650
Honda might be for you. There are some drawbacks to a unique piece of history
though. Parts, or the lack thereof; Honda made the usual amount of spares for a
motorcycle but 28 years have passed and most of those spares have been used up.
Ebay has become my new friend when it comes to parts for the CX650, though it
can be rough sorting through improperly labeled stuff. Another problem is that a
28 year old spare part sometimes is no better than my current 28 year old broken
part. As time passes, parts are going to be harder and harder to find. Owners of
the CX650 Custom are starting to look seriously at alternative sources of parts;
other models of Honda produced around 1983, other makes of motorcycles, and
aftermarket parts that can be modified. For instance, my water pump seal is a
known weak point. This means that the parts are disappearing at an alarming
rate. One savvy owner decided to track down another source. Turns out, 2005-2007
Yamaha FZ6 motorcycles used the same part source!
 
Now we come to the point of my discussion, the 1983 Honda CX650 Custom Infosite.
I’ve taken it upon myself to put together a single source of information for my
motorcycle. That way if someone needs to get parts for their bike, they can find
everything on my site.
 
* Need a copy of the manual? Download it off my site.
* Need to know where a part can be found? Click the link on my site.
* Need to know how to do something on your bike? Read the how-to on my site.
 
As time passes, I hope to add more and more to my site so that my fellow CXers
can continue to keep our bikes going for a while longer.
