NCY 15/36 Upgear Set - GY6 125/150cc Scooters

Let your GY6 build stretch its legs with the NCY 15/36 upgear set. Made for compatible 125/150cc GY6-family transmissions, this two-gear performance upgrade will raise the gearing by 22% compared with a stock 13/40 set, helping a big-bore setup reach higher top speeds with a more usable rev range. 

• Performance gearing: 15-tooth countershaft gear and 36-tooth final-drive gear for a taller ratio than the listed stock 13/40 set.
• Big-bore pairing: Helps compatible GY6 performance builds make use of their added power.
• Two-gear set: Includes the pictured small countershaft gear and larger splined final-drive gear.
