Dream vs Hawk Riding

[Waveblaster]

Hello

I took the my recently rebuilt 64 305 dream out for a long ride today . It was great riding weather so had to make the most of it!. I noticed that there is a degree of vibration at 55 - 60 mph. Not a big deal but noticeable. I guess this can be attributed to the 360 degree crank design.

I am curious to know from those who have ridden both the superhawk and dream and the differences around ride and smoothness. I understand the hawks run the 180 crank and I am interested to know how this affects the riding characteristics at cruise speeds.

regards

Greg
