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

received this item today was only posted yesterday wow i was shocked but in a good way of cause well recommended seller will be purchasing more off of this site

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

Bought and Installed on RC 2018. Excellent strength, the full kit that is provided is excellent value for money and much better than other providers. Sprocket especially is a great upgrade. Visually it looks great, I will aim to get some photos added to show final product.

Great item fast delivery just what I needed for my bike to get it through its mot thanks

I've added this upgrade onto my bike it's perfect only thing I found was that the front sprocket was a little loose even with the washer. I'm hearing some noise but unsure if it's the upgrade so I can hear the chain go more now if if there's a problem. ============== Admin Reply: Thanks for your feedback, glad you love it like others do!💎 - If your font sprocket has a rattle, please investigate your drive shaft itself, we don't know if your own previous sprocket splines caused any issues to it etc, remember the original OEM sprocket from Hyosung is made in China, another owner made his bike chain adjustment too tight and he lost his engine shaft, so it was a mess! (his own fault) but the original sprocket was badly worn even inside the spline teeth connecting to the front engine shaft , so double check your setup! Remember to check chain slack and keep it lubed well!

The best upgrade you can make on this bike. Those sprockets change everything - acceleration, higher max speed, better rmp/speed ratio. I'm super happy and I'd do it again, anytime. The only suggestion to Marcel I'd have is to offer the front sprocket with rubber to make the chain work quieter with less vibrations. All the rest, 10/10!

BUY THIS NOW! I have no regrets, this kit is amazing, amazing, can tell the difference after installing. I had great support and help through the buying, delivery, and installing, and I honestly wish I had done this sooner. And honestly, guys, get this. Ride safe fellow riders!

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.

Installed on RC 2018. This will be longer than most reviews but want to get all the details down to help you guys decide. Ladies and gents, the big ticket item on here for the GT family. If you enjoy performance and speed, then my god is it worth it. The damping and preload makes bumps and crests effortless, no bottoming out and chain is free to do it's thing. I have managed to test it here in Ulster on the road race tracks (not when closed roads sadly) and it performed like a dream, ride flows from section to section, cornering is massively improved, I can't fault it. Adjustment is relatively simple, I'm 85kg/6 ft4 so some adjustment/firming was needed out of the box, but all very straightforward, plus a higher set ride height is noticeable for me. Installation is one for one with OEM, would recommend mechanic there to give the bones and links a once over/lubrication and for an extra pair of hands. It is a larger price tag, but it's not everyday we get a company like YSS making a specific product for Hyo's. If you are on the fence, then definitely go for it.
