“I first saw a Hyosung GT 125 Comet in 2003 and I liked...”

Written on: 10/03/2005 by DanLeeds10

Good Points
Very comfortable, strong 4 stroke v-twin engine and a tall, well balanced riding position not to a mention totaly oversized which isn't a bad point because the power the engine gives hurls a respectfull 85-90 mph on a flat!

Bad Points
Short gear ratios on 1st and 2nd and 5th is too long how ever there is a 250cc model and its easy to change the sprockets over. Because its still an uncommon bike to come accross after market mods like cans huggers etc have to be made at a cost! Some of the powder coated parts are poorly done but these are sorted under warrenty easily.

General Comments
I first saw a Hyosung GT 125 Comet in 2003 and I liked the Bandit looks from the word go. Well on the 18th of Decemeber 2004 I took the plunge and bought the updated model (look for the biggger head light). When I first started riding the comet it could only achive a poor 60-65mph top speed but the more miles and revs it got the more the speed increased to a quick 85-90mph at a constant and I have finaly just clocked 100mph down hill in good weather, so its sluggish when your breaking the bike in but it adapts very quickly and after the first 500 miles and then the fun really begins. Because the frame used to build the Comet GT125 and GT250 is identical to that of the Suzuki GS500E its very big for a 125 and I stand at 6ft so its comfortable and because the frame is oversized every other part of the bike is and this gives fantastic performance and looks!



The rear wheel on the comet is bigger than that on a 600cc Bandit it corners beautifully without a single effort and if you have the guts it will drop right down to the danger balls on the foot pegs and come back up with some but not a lot of effort.



Now if you were reading this carefully you will notice that there was a reference to Suzuki and thats because the designer for Suzuki also designs for Hyosung and its purly a Suzuki that has bits from a Bandit here and bits of a GS500E there and it works perfectly.



All i'll say is get your cheque book out because its the best £2600 I have ever spent but be carefull because I think the price may go up shortly as this bike will hit off to compete with the RS125 especially when 2006 euro legislation kicks in about 2 stroke engines but the Hyosungs beafy 4 stroke wont be affected by this.



This is a growing bike and its the best 125cc on the road today.

Hey, I've had a Hyosung GT125 for about a year now, and I'm always looking for more speed.
<br/>I've changed the jets and put on a performance exhaust, but that hardly made a difference.
<br>
<br/>If anyone has any ideas on picking up performance please can you let me know here on on the Review centre forum?
<br>
<br/>Thanks.
<br>Renny.

Steads Motocycle shop in Dagenham, East London have a showroom full of every Hyosung motorbike there is! They are a Hyosung dealer and have all the spares and performance parts you will ever want! I have a Hyosung GT125R. I brought it from this shop, when I got it, it only hit about 70-75 mph, after fitting an end can and fiddling around with the engine it hits about 95 mph. Great bike.

Well the best way to make a GT125 go quicker is to remove the catalytic converter in the rear exhaust, this really makes a difference, also if you don't already know the catalytic converter is the funny lump of metal welded to the end of the exhaust and when you remove the exhaust can, looks just like a bit of cardboard if you look inside it. Well just carefully remove this with a hacksaw then fit a Blueflame exhaust with the baffle removed as this also makes hell of a difference.
<br/>Hope this helped, oh just to let you know run the bike in for at least 750 miles before you expect to much of a dramatic speed change.

MAZA: Please can you go into more detail as to what Mods you had done since I live no where near the garage you mentioned.
<br/>As for top speed mine only does 55mph but I think it may be since it’s only got 1500 miles on the clock and wasn’t run in properly by last owner?

I've changed the can to a 250 one because I was told it would go faster got to 60mph. Guess what had a Yamaha yb100 over take me - talk about shame.

Apparently they take a while to break in. Since mines got less than 1500 miles on clock and still only does 55mph. Other friend with them say the engine loosens up after 2K onward.

Does anyone know if it would be possible to fit a Suzuki gs500 performance can to a comet 125? I know that they are basically the same bike and want to find a decent can for it.

I have bought 125 gtr. I think its a good bike for the money. I have not done any mods as yet as it has only just had its first 600 mile service. I've had a top speed of 78m.p.h so far but that was at 12000 revs. It doesn't accelerate very well but I'm hoping to sort that out in the not too distant future. Do the mod chips work?

We love hyo's. I have had a GT125R for a few months now. Big characterful machines with surprisingly good mechanics. You can find lots of help, support, tips and modifications for Hyo machines at http://ukhyo-ownersclub.co.uk
