Reply To: 520 upgrade – Chain & Sprocket Kit Discussion for GV125-S Gv125 S EFi 2022
Yup, that’s Hyosung! – They use either a “stud and nut” with lock tabs OR as you witnessed on yours , “Full Concave/Countersunk Torx” bolt.
Just as they made very slight changes to how long the chain adjusters are (eg. 140 on early models vs 138 link OEM chain used on later models), and hence I no longer supply bolts for the rear sprocket as it depends what hyosung chooses to do with their hubs! – Rear sprocket not an issue , just as long the original bolts are used or replace to stainless for the same ones.
Have a good weekend!
