The legendary classic cars revived here now compete across time at Mobility Resort Motegi
Vintage and classic motorcycles from the 1960s and 70s that have been preserved and restored
gather at Mobility Resort Motegi for an event that tells the story of the good old days in modern times,
Good Old Days Motegi. The opportunity to see particularly rare machines racing on the MotoGP™ course as a special event
is also a major attraction.




The 'CB72' tuned by Mr. Hideo Yoshimura (commonly known as POP Yoshimura) featured innovative tuning at the time, excelled in numerous races, and greatly contributed to the development of Motorsports.
Seventy years after the founding of 'Yoshimura,' Fujio Yoshimura, the eldest son of POP Yoshimura, will perform a demonstration run of 'Team Yoshimura Honda Racing,' which symbolizes the dawn of Japanese motorsports, at Mobility Resort Motegi, where the two-wheel world championship MotoGP™ is also held.

Excerpt from Moto Maintenance magazine, released in 1995
