Original Yamaha / Nippon Seiki mechanical tachometer believed correct for 1973-1974 Yamaha TX500 and TX500A motorcycles.
Research matches this style to Yamaha tachometer assembly numbers:
371-83540-00-00
371-83540-03-00
Features the distinctive original face with
12,000 RPM scale
HIGH BEAM indicator
BRAKE LINING warning indicator
NEUTRAL indicator
YAMAHA logo
Nippon Seiki Japan marking
Mechanical cable drive
Tachometer has been tested and is working properly.
The face, needle and markings remain readable. Housing and bezel show typical age and storage wear, including oxidation and finish deterioration. Please study all photos for exact cosmetic condition.
This design is a much stronger match for the TX500/TX500A than the RD250B.
Some interchange references also associate Yamaha part number 371-83540-03-00 with the later XS500, but I would advertise the primary application as 1973-1974 TX500/TX500A unless a number stamped on the back confirms the exact version
