Can anyone offer their opinions please.
The 80s/ 90s Kawasaki GT550 shaft drive VS the Yamaha XJ900F or the 650/ 750 variants.
If these two old timers, in your opinion which of the two had the best as in best handling Frame /chassis set up geometry etc ?

Only ridden the xj550 and xj1100 maxim. Liked both bikes. The 1100 was very smooth.

I have riden XJ900F built a cafe racer, the handling was not what i would class as inspiring, i still have several XJ900 f engines and lots of parts even a bare frame swing arm and stripped front forks. I however have a quite complete rolling with its own reg documents GT550 minus its engine, and today a tape mesure hinted one of the XJ900 motors would probably fit the Kawasaki frame.
Thinking if the GT550 was a decent handler i might just try shoehorning in the 900 yamaha motor. i never had a Yamasaki before.
