Usage of this Modified Cyclone version can be quite confusing. This YouTube video gave a fair explanation on its history. Note video is in Mandarin narration.
Kamen Rider TV series back in the 1970s were made with little consideration for smooth flow and logic. Within a single episode, the Kamen Rider can be seen riding on 2 or more different "Cyclones". A logical explanation is different snippets filmed on different times, were stitched together scenes. Recycled scenes were also used in different episodes on Kamen Rider riding his machine(s). Therefore Hongo was also seen riding this vehicle. As the series move on, it is quite clear Kamen Rider Old Nigo should be the rightful owner of it.
