Thank you for viewing! This is a key set for an NS50F. It's a set of three: the main key, the gas cap, and the helmet lock. It should all work with one key, but the gas cap is stuck and the key cannot be removed. Although this is a problematic item, NS series keys are becoming increasingly expensive, so why not take this opportunity? Please consider purchasing with the understanding that this is a defective item. Returns are not accepted after purchase. #NS50F #NSR50 #NS-1 #KeySet #NS50R #Parts
