Generally over here in UK we use this kit by many 125 n 250 owners.

Uprated Japanese 520 Chain & Sprocket Kit :: Hyosung GT125R GT250R GT125 GT250


Also the best front sprocket aftermarket would be the UK made RENTHAL ones.  They are on the shop page.


I am looking to see if I’ll stock up PBI (US) sprocket, i believe i may have found one but will be sure soon lol.


As for chains. You will want to use a japanese one over cheap aluminium copies.
