it fixed most of the problems that the original CB750 suffered, some due to Honda's attempt to keep the cost down
Could you elaborate on these?
When the original production Honda CB750 was released to the public in 1969, many were surprised at the low price of less than $1400, which undercut the Triumph 750 Trident and BSA 750 Rocket III by several hundred dollars, which was Honda's intention. But in order to achieve this, many features that appeared in the 1968 CB750 prototype at the Tokyo motorshow was changed with cheaper items, like simpler side cover badges, less fancy chrome gas tank strip and most important, switch from the duel throttle cable system of the prototype with a cheaper single cable unit with cheaper carburetors, along with many other small items. But when CB750 became a success, many features that originally appeared in the prototype reappeared in their new and improved 1971 CB750K1 model, but the carburetor type didn't change until the 1977 model run. Early production CB750 suffered delays due to labor strikes back in Japan at the time so the original release date of April 1969 was pushed back to June 1969 and even then dealers had a hard time getting CB750. As a result, some parts to complete about 20 CB750s were shipped to the United States earlier so they were assembled by Japanese and Americans so some can be registered in April 1969, some even made it to Canada. None of the 1969 CB750 made it to England but when they were introduced at the English motorshow in April 1969, it was a pre-production model that featured the production engine, side cover with emblems and seat but also had the same front end and gas tank from the 1968 Tokyo prototype. Honda made many recalls to improve their early Honda CB750s. Early Honda "sandcasts" suffered from destroyed cases due to main drive chain damage and original smooth oil filter cap was changed to more rugged finned version because people kept over-torquing them. The best improvement list can be found on My. John Wyatt's excellent Original CB750 book, even though his information on the prototypes are little inaccurate but then without Honda's original documents, it's hard to be certain because Honda of Japan kept dark about the prototypes even to the American Honda.
