The Honda CB400F2 was indeed one of the last Japanese motorcycles to feature classic stays on the front fender. The CB400F2 was a model produced by Honda from 1992 to 1997. It was a retro-styled motorcycle inspired by the classic Honda CB400F Four of the 1970s.
The classic stays on the front fender were a design element that harkened back to older motorcycle styles. In more recent years, motorcycle designs have tended to move away from this traditional aesthetic, favoring sleeker and more modern styling. Therefore, it is less common to find motorcycles with classic stays on the front fender in modern production models.
It's always worth checking the latest offerings from different manufacturers to see if there are any models that incorporate classic stays on the front fender.
