Bike listed is a new condition 1974 BSA B50MX / Triumph TR5MX. (Bike is badged a BSA and VIN number indicates it was produced in March of 1973. but Manufacturer's Statement of Origin labels it a 1974 Triumph B50MX. )Matching VIN and Frame numbers: VIN: B50MXCH01104 Frame Number: 01104Original English Dunlop Sports tires with most of the new tire 'hairs' still visible. This bike is in new condition and has never been started. It has been stored indoors since 1974 and I purchased this bike from the estate of the original owner. It still has the original spark plug seal (see photo). and there is no carbon in the exhaust. That being said. sitting in storage for 40 years can cause some wear. There is a dent in the exhaust mufflers (see photo) and a tiny ding in the gas tank (I took a photo but the dent is too small to show up). The paint and decals are in excellent condition. Also comes with new-in-plastic BSA B50MX Owner's manual. If you're looking to add an excellent bike to your collection. or just want a new bike from 1973
