Below is an interesting history of the development of the DT1. Very informative and worth the few ads you need to skip.


 

Very cool.. at about 11:30, I saw the slow motion of the forks getting a vigorous work out. Amazing!

Yes just watching that bit.
First saw that part [or maybe the whole video i'll go watch] when we went to a Yamaha Dealers school learning about new models before their release i think, be 1970.
Anyway the gasps from the audience was interesting haha.
It's a wonder anyone wants to get them them off the ground after watching that.
Reminds me of my old Matchy [Matchless] 500 when slightly above idle the forks looked like they flexed about half that amount with each motor pulse.
Wasn't worried then but would be nowdays.
