*UPDATE*
I'm in the process of writing a more comprehensive review having now owned my bike for over a year. In the mean time I have made some updates to this page:
You can now enlarge and scroll through all the photos without even leaving the page! Simply click on a photo to enlarge it. Click on the right side to go forward, click on the left side to go backwards. (Thanks to the hardworking people over at LightBox JS.
The "Hyosung Comet Photos" and "Hyosung Comet Movies and Photos" links now take you to my Comet4Sale page simply because I have a very cool slideshow and a bunch of embedded movies there - saves you having to navigate away to youtube and such.
Summary

I guess I wasn't the only one hard up for information
on the Hyosung 250 Comet when I bought it. "Hyosung
Comet Review" searches in Google keep bringing
searchers to this page. Having now owned my Hyosung
250s just over six months, I feel I am able to
write a more comprehensive review. This review will be
broken down into the following sections:

Overall Impressions

Overall, I have to say I am completely satisfied with
the Hyosung Comet. It performs well for what it is... a
250cc naked bike. If you're expecting it to be on par
with larger japanese bikes you'll be disappointed. This
bike is ideal for everyday riding. It performs well in
the city, on the open highway and even in the dirt! In
short, I would recommend this bike to anyone looking
for a cheap, good looking, comfortable and versatile
bike.
Pros
-Cheap: Around $2500 USD new (Here in Korea)
-Fule Economy / Milage: The Comet has large 17L fule tank. I avearge 320km to a tank under mixed driving
conditions and up to 340km per a tank on the highway. At around 300km I usually have to swith to
'Reserve' fule.
-Good looks
-Comfortable
-Dirt cheap maintenance (Here in Korea)
Cons
-It's only 250cc
-Really lacks any noticeable power-band
-The gearbox makes loud clunky sounds when shifting
-Electrical is a little shoddy (could just be my bike)
Personal Background

I've included this section because I feel it's
important that you first understand the person writing
this review. A persons age, experience and physical
characteristics are all factors that undoubtedly bias a
reviewers opinion. If you and I share many similar
characteristics there's a good chance this review will
be of more relevance to you.

Riding Style:

I ride this bike like it's stolen. It was cheep, it was
used, and parts and maintenance cost close to nothing
here. In the past I was my own mechanic but here in
Korea I don't have the luxury of having my tools. My
alternator has been shot for the past 6 months so every
time I go riding I jump on, run, pop into second and
ride away. These cold starts in -10* couldn't have been
good for the engine. Still suffering from the loss of
my Suzuki DRZ 400s dual-sport, I occasionally try to
fill the void by venturing off road with my Comet. So
far my buddies on dirt bikes have had trouble keeping
up with me in the dirt. As soon as they have more than
a few months riding experience I know this will change.
What all this boils down too is the fact I am extremely
hard on my bike. Surprisingly, I have had no major
problems.
Looks
The 250 Comet looks good - click
here to see for yourself! The big round headlight
nested into the copper shocks gives the bike a more bad
boy, curser style look from the front. From the back
and sides, she exudes more of a sport bike appearance.
The silver cargo rack that came with the bike defiantly
detracts from it's overall appearance... I can tell I'm
getting old when practicality begins to out way what we
in the army liked to call the LCF "look cool factor".
The bikes best feature is its sleekly styled, oversized
fuel tank and big, deep saddle.
Performance

Once again, if you're looking to buy this bike you'll
have to seriously consider what riding expectations you
have. Forget doing any wheel-ies or burn-outs right
now. I seem to have done things bass-ackwards in my
biking career. I learned on a 550cc, then stepped down
to a 400cc and now find myself riding my smallest bike
ever. I don't notice the lack of CCs at top speed, as
none of my previous bikes were really capable of going
that fast, but rather a lack of acceleration and power.
But I really can't dwell on this too much as it's not
like Hysoung is trying to conceal the fact the Comet is
250cc. Whenever I feel down about my bike being
underpowered I just jump on my buddies 125 RXR for an
hour and my bike feels like an 1100 CBR after.
