I only use the standard setting sprocket the manufacturer wrote in manual. This raw bike machine is tested well in factory and they come out front and rear sprocket size is the best. Also the digital meter speedo gets input from front sprocket gear spin NOT from front wheel spin.
wheel bearing u can change to KOYO or NTN but must be "covered" type and not those open can see ball bearing. Yes. bearing also helps reduce vibration.
my extra tensioner + cam guide one set is for future use. Cannot sell.
why u need all above. Since in setia tropika they have all parts and will do one short everything for u.
