I thought the Quadrant was based on the 500 cases with a extra casting added to the centre? .I'm sure i read somewhere the bike may have been available long before the CB750 mid 60's maybe.........anyone remember the prototype Yamaha...looked a bit like a XS650 but had a watercooled 750 /4 cylinder 2 stroke engine (TZ?).

Or the good looking Harley that eats sportsbikes.

More chance of the Loch Ness monster biting Auntie Helens head off than that happening.

That was the Trident,a 500 with a centre case,well sorta.Quadrant was another cyl,just an exercise to see if it could be done - but there was no real need to,the Trident could clean up a CB750 in everyway....except relability,and the ability to keep marching forward.They thought they had done enough and the world asked for more,and got it.

Yamaha had quite a few big bikes in the wings,including a rotary,but after the TX750 and TX500,I think they just stood back and watched the rest.The XS650 was almost British in that it was aimed at a market that moved,but they kept with the very good design.What was the first 4cyl Yamy,the XJ?

The BSA/Triumph 350 twin was another design that was pulled just on release,the press had even ridden and done test reports on the bikes.The story is that the market had shifted away from 350s onto 750s,but it may of been more than that.A Triumph Bandit sat at Whites for a few years,story had it that the engine was just a wooden mock up,but I don't know about that,I saw it on the showroom floor,and it look real enough to me,but it may of been hollow inside.
