520 Upgrade Chain & Sprocket Kit [Conversion] - Hyosung GV125-S EFi Bobber 125 S

It really does make big difference I’m just not sure about the front sprocket Because I see the one on shop it has 14teeth I recited 13teeth But I’m very happy about this upgrade Thanks Marcel

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.

Uprated & Braided Fuel Line + Filter Kit - Hyosung GV125 & GV250 {Carby Models}

New fuel lines are just awesome! After upgrade my bike starts immediately - my problem with starting is over now. Very good quality.

520 Upgrade Chain & Sprocket Kit [Conversion] - Hyosung GV125-S EFi Bobber 125 S

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!
