Replacement / Upgraded replacement Starter Motor Drive Chain for Zongshen 190cc ZS190 Engine! 

For some engines/starter chain set up, this is considered an upgraded starter chain, which is thicker than the normal starter chain by 0.17mm, which is about a 14% increase! 

For the later generation of ZS190 engines, this size chain would be considered a replacement as some later engine received an update to the starter chain. 

• Links thickness ~ 1.19mm
• Earlier years factory thickness is ~ 1.02mm

For the ultimate starter chain upgrade, please look into the Spata Bullet Proof upgraded starter chain and starter gear upgrade SKU: RS-1001 with optional starter clutch upgrade as well!
