In Japan & Singapore, there is a niche for 400cc bikes due to their licensing structure (in Singapore for example, Class 2A license lets you ride up to 400cc, a year after holding a Class 2A you can finally move up to the full Class 2 to ride anything >400cc).

There is no such niche to create a demand for 400cc bikes in particular, unless they create this niche via pricing instead.

I don't know how they're going to do that here though to make it even worth their while.

I used to own a GSXR400-RR - it was a fun tool to terrorize the 750s in Batu Tiga circuit, coz you could outbrake the heavy 750s into the corners. When the Sepang circuit opened, it was kinda pointless...

Keeping the engine on the boil was part of the fun, but yea it was gutless in the lower RPMs. It was a lot like the 2-stroke 250s of the time - RS250, RGV250 etc.

The old Japanese 400s tend to have a low seat height and I would have happily gotten the CB400 SuperFour for the wife if it weren't so fucking expensive for what it is.
