Reply To: Levers – GT125RC
you will need an OEM GT650R master cylinder (actual one) & clutch perch mount to consider using their thicker adjustable shorty levers you see online. The OEM 125cc master cylinder will not fit 650 levers.
Others resorted to “universal” aliexpress master cylinder and clutch kits but you will be back needing a new clutch cable, Hyosung’s OEM perch stays undefeated , plus i can’t trust £10 master cylinders in emergency braking. So I avoid them.
If not, get OEM Kawasaki ZX9 Front master cylinder and use its shorty brake lever. As for the clutch side, you will study how to implement a hydraulic clutch (custom work & time consuming for a novice to fine tune it) , i’d recommend staying with traditional Hyosung cable setup. Hydro is overkill for 125cc & more maintenance jobs to keep on to off.
