Yamaha CS3C, CS3B and CS5 Coverage
Yamaha's official U.S. model mapping identifies the CS3C for 1970, CS3B for 1971 and CS5 for 1972. PartsNMore's legacy product tags list CS3 and CS5 across a broader 1970–1972 matrix, so this collection deliberately asks shoppers to verify the complete model code instead of repeating every tag as confirmed fitment.
The current Yamaha CS item is a stocked fork-seal set measuring 30 x 40.5 x 10.5 mm. Its product record spans several makes and models; only the exact listing and a dimensional match should be used to confirm the seal.
