I don't recall seeing this before. Thanks for posting
After watching the vid, my personal choices:
I still stand by my 300. Being of short stature, it suits me, and is a decent performer.
Next choice would be the R3. Due to the suspension and braking review, has set me back in making a deliberate decision to getting one soon.
Next choice is the RC390. Although the best performer of the four, I like the looks of the R3 best, then the 300, then the RC390. It is rated being the tallest of the four as well. Being 5' 1", I can't get two feet on the ground on the 300. Doubt I would be even close on the RC390. Although, if I had a choice of the KTM, I would choose the Duke. For me, it's a better looking bike.
Lastly, the Honda. Rated for best suspension and braking, but lacks power. For me, aesthetically, is bland.
