520 Chain Kit & Clutch Upgrade.
The 520 kit is one of the best life changing mods for the GV125-S , every customer i know did not go back to stock 428 skinny chains & tiny sprockets.
Clutch = It just compliments the 520 upgrade, your clutch will have a bit more punch 👍
Exhaust = Get a garage to cut yours and weld a 51mm cone ===> Get / Find a full size 51mm exhaust muffler that you like
but remember All GV125 including 2001 models all the way to 2025 models will run SLOWER if you do not keep DB-Killer inside. It is because GV pipes are too short compared to Hyosung GT bikes, the GV models I tested (both carby and EFi) always hated it when I installed very small exhaust cans
Yes the noise is good , but the performance was rubbish. I used OEM exhaust and drilled a bigger hole for nice sound and the other bike I used OEM Harley 2022 exhaust pipes as a custom job.
Chinese cans from China = I did not care to try , they look like they will rust in 2 winters and look poorly made. The EU where we live is very salty and wet , especially UK!
If you want a good example of an exhaust that does not make your bike slow ==> Look at LEOVINCE Exhausts for GV125 and GV250 , then ask your mechanic to see if he can do something like that.
Whatever exhaust you have , make sure it is long enough to reach the chain adjuster
