89-90 750-1100 Frame Differences

OK. So growing up in the 80's I have always had a 1st gen bike. But lately I have been getting into the 2nd gen bikes.

What are the differences between the 750 and 1100 for 89-90?

School me.

Re: 89-90 750-1100 Frame Differences

The 90 750 frame is a bit taller , so its the best for 7/11. You don't need engine removal for valve adjustment.

89-90 1100 and 90 750 frames may be the same but , they also may have different head angle.

Ghost probably knows.

Re: 89-90 750-1100 Frame Differences

I have 3 now. 2 are deff 750 frames but they are a little different. One has bolts that hold the tank bumpers and the other does not have any bolts, they just glue on. The sub frames are slightly different too. One has more bolt holes and brackets.
The other frame I do not know if it is a 750 or 1100 frame. There are no Vin numbers on the head tube and they have not been removed.

I think the lower engine mount has a larger hole on the 1100.

Relaxed steering geometry in 1990 750 to fit the curved cooler.

I think the 1990 frame gained some weight too,
but just relying on (flawed) memory for that
