Was made by HRC I heard .Seen those on the same year NSR500The RVF750 in its various versions was, in my opinion, one of the finest racers ever made.
Thanks for the pictures.
PS: are those HRC-stamped calipers an in-house design?
Stunning scans as usual Simon... I saved them all...very rare magazine find.beautiful shots of the 1990 RVF750 factory 8 hour machine I saw Wayne Gardner ride this for a few laps back in 2007(little promo race with T Taira) the power and response seemed as good as a modern factory bike
