Upgrade Clutch Springs & Plates Friction Drive Overhaul Kit - Hyosung GV125-S EFi (Injected)

Upgrade Clutch Springs & Plates Friction Drive Overhaul Kit - Hyosung GV125-S EFi Bobber 125 S

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

Premium 520 Chain Sprocket Kit - Hyosung GT125R GT125 GT250

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!!

EBC Heavy Duty Clutch Plates Friction Drive Overhaul Kit - Hyosung GT125R GV125 GT125 XRX125 RT125D GA125

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

EGR Valve Blanking Plate / AiS Delete Block Off Kit - Various Hyosung Carb Models

Bought these EGR blanking plates the other week and they look spot on, were delivered quick too. I'll upload a picture once I've rebuilt the engine. Cheers

520 Upgrade Chain & Sprocket Kit (Conversion) :: Hyosung GV125 Aquila

Gfreak120

520 Upgrade Chain & Sprocket Set (Full Conversion Kit) - Hyosung GV125 Carby Aquila

Chain worked well for a few months, had 85mph on flat, compared to normally 65, however it's been roughly 3 months and now the chain isn't holding between rides, tightened it and became slack at the end of the same ride, resorting to a max of 65 down hill, have taken 2 links out and tighten with chain slacking still got the same problem, not impressed by the quality of the chain, in total I've done less than 600 miles on this chain. Admin Edit = Customer bought kit in July 2026 and reviewed in September 2026 ,we are waiting to hear from customer about their bike configuration at the rear end (if badly worn cush drive was at fault , or carrier bearing or too tight chain adjustment, or chain was skewed // instead of straight || etc ) - We supplied a world class AFAM gold chain made in EU, so 600 miles is worrying for us and not good. Fortunately, the sprockets are fast and appear intact, we will await their reply for us to investigate the "chain" premature wear.
