    What a great kit this is!! Delivery to belgium was very quick! I'm happy with the result. Don't have to shift as mutch as with the original chain. Lower revs and more accelaration. And a higher top speed. If you buy this kit you won't regret it!! Top notch! Thanks marcel!!! Greetz from belgium
  • Fast X-Ring Upgrade Chain & Sprocket Kit :: Hyosung GV300S
    Erick
    After installing this kit, my 300 can really cruise through every gear without screaming through the ram's. This bike is immensely more enjoyable to ride now and I often leave my iron 883 at home to take the aquila out for a ride. If you only do one thing to your Aquila 300, install this kit. I promise you won't regret it. Great parts, great service. E.

    MARCEL ROCKS! Not only is this kit is a must have upgrade for your bike, but the support and advice i've got from Marcel is amazing! You should now that this is my first motorcycle and I really love to make my hands dirty. I love my bike but the acceleration was a bit disappointing. I've read about a tooth more or less on the front or back sprocket, but i really didn't wanted to loose any top speed. It seemed to be one or the other (more acceleration more top speed). I talked to my dealer about this, but I didn't find any help there. So I contacted Marcel. He sent me the kit and the delivery was very fast (I live in Belgium) Then came the moment of truth: would I be able to do the upgrade myself? I succeeded with easy with some remote support from Marcel over messenger. His reaction time was very fast and I didn't loose time with the procedure if i had a question. Many thanks for that Marcel. The day after the installation came the second moment of truth. Would this upgrade perform as advertised? In short: IT DID! The test ride with these sprockets / chain exceeded my expectations . The acceleration in gears 1-4 is superb now. In second gear i can pull up to 50km/h - in 3th to 70 km/h without going in the red range! The bike pulls really fast now. About the top speed, with original chain kit my top speed was 107km/h on a steep downhill. Now on a far less steep one i reached 119 on display and gps speed was 107 !!! Speed record easily broken.

  • 520 Upgrade Chain & Sprocket Kit (Conversion) :: Hyosung GV125 Aquila
    Oliver
    After reading the reviews and speaking to Marcel I decided on getting this kit and I'm glad I did. Great quality parts and I have noticed a change in performance. I can now get 90mph out of it, which is crazy for a 125 cruser! It will comfortably ride at 70 all day and acceleration has improved to for safely getting away from idiot drivers haha! Would highly recommend
  • Aftermarket Rear View Mirrors (OEM Style) - GT125R GT250R GT650R
    MattHyo627
    Installed on RC 2018. Wing mirrors are excellent, exact replacement for the originals. Still maintain that sporty, angular look, as much as you can with bike mirrors. Service excellent as always from Marcel/Hyo riders team.

  • Clutch Plates Friction Drive Overhaul Kit - Hyosung GT125R GV125 GT125 XRX125 RT125D GA125
    Kevin Barrier
    Wow such a huge difference, finally changed this myself. Not too scary. Straight swap for old kit. Didn't even need a gasket. Much sharper gear changes and acceleration. I highly recommend. On a scale of 1 to 10 it's about a 6 in mechanical knowledge. Remember to soak the plates and don't over tighten the bolts. It's a full oil change so have at least 2 litres handy
  • High Performance Ignition Coil :: Hyosung GV GT 125 250 R + RT RX 125
    eman ellul
    Just upgraded to these coils, the uprated regulator, the uprated stator and ngk caps with iridium spark plugs. I have to say it made an amazing difference, the bike almost no longer needs choke (less than a minute and only on first start in the morning), acceleration has improved significantly and my bike is now charging (which was my original problem :p). Very happy with all items 🙂
  • 520 Upgrade Chain & Sprocket Kit Conversion Hyosung GV125-S EFi Bobber
    Sheldon - GV125S EFI 2021 - UK
    After a little bit of a struggle I finally got the kit on! Thanks to the forum post that front sprocket was a right ass to get off! The bike feels much nicer to get up to speed, it feels a lot smoother and nicer to ride! So far I’ve noticed an increase of about 5mph on the top speed but I haven’t pushed it to see how far it will go but that extra 5mph gives a more comfortable carriageway experience. Highly reccomend!

    So got this set few weeks ago as i wanted a bit longer gears. im using it in city, heavy traffic, daily commuting. Before was changing gears like a lunatic 1st to 4th non stop.. this set sorted my problem a lot to be fair. 20-35(40 with screaming engine) mph in 3rd gear. 2nd gear comfortably around 25.. unfortunately havent tried whats the max speed now as grown up life sucks and havent had time to push the bike yet

  • Upgrade Clutch Springs & Plates Friction Drive Overhaul Kit - Hyosung GV125-S EFi (Injected)
    TomaszG81
    Highly recommend to install this kit. The clutch reaction is much better, lever is more stiff, clutch action is more punchy. Super nice feeling when you change the gears. I have the impression that the bike is less jerky on 1st / 2nd gear when you ride with small speeds. I love the kit and I'd do that again without any hesitation
  • 520 Upgrade Chain & Sprocket Kit Conversion Hyosung GV125-S EFi Bobber
    Stuart
    Really great. Low end acceleration is much better and gets up to 60 in 4th (used to have to use 5th for this). Got it up to 70mph, although it did take a while (previously only got up to 67pmh), but I ran out of road. Pretty sure it would have been up to 75mph+ on a longer carriageway
  • Uprated Japanese 520 Chain & Sprocket Kit :: GT GTR 125 250 RC Hyosung

    Bought for 2016 GT. Straight forward swap out. Bike feels better geared in all gears. No massive top end gains but worth it for the increased rideability!!

    Where do I start? The beginning I guess 😉 I bought this Beauty, a GV125-S last Month and was not happy with the Power and acceleration, or should I say missing Power of the 14 PS compared to my last ride a Yamaha XV 125 with 11 PS. Dont get me wrong I noticed the difference, but she was just laggy, screaming at me, and the Vibrations when going above 8000 Revs. In 5th gear she hit 10-11000 revs and just stopped power wise, not going any faster than 105 Km/h on the dial. In the German Group on Facebook it was suggested to upgrade the front Sprocket to one with 15 teeth, which I did, She run a little smoother through the Gears and the Engine sounded a bit quieter and wasnt screaming at me, but the loss in Power in the lower Gears, especially going from 2nd to 3rd, and the Top speed of 110 Km/h, which took me ages to get there, wasnt satisfactory, taking her up into the Red again to get here.. Then I saw Marcels post in that Group and decided to buy this Upgrade from the UK and have it shipped to Germany, thanks to Marcel here for the support. What can I say? I took her out on a 3 Hour ride to test, what a difference! The smaller front Sprocket (13) and the Larger Rear Sprocket (Dimension) and 520 Chain is the perfect combination. She shoots up through the Gears, no Jerking, no screaming Engine, next to no Vibrations, just smooth and fast, at 9-10000 Revs in 4th Gear she hits 100 Km/h and in 5th I had her at 120 Km/h and felt like there was still more .... plus it was a windy day 😉 I also ordered the NGK Spark plugs and HT leads which just finishes off a perfect combination. Thanks Marcel and Team, Season nears its end and I just cant wait to get out there next year, the Bike is so much fun now and I dont miss my Yamaha at all 😉
