Jeff,

Hello.
This is the story from original designer of Bridgestone motorcycles.

In those days, 350GTR to 400cc version was tested in factory.
It was very nice feeling but they decided to sell 350cc for requiring of the market.

And then they planed big flag ship "V4 1000cc with shaft drive " but it was only drawn as sketches.

Thank you,

Kotaro
