Having owned both the 600 and 900 Hornet and an MT-07 I can kinda see the comparison as all 3 are let down by budget suspension. I disliked my 600 Hornet as it was an IL4 scream machine with crap suspension. The 900 was the better one of the two by far.
The MT-07 has a peach of an engine, albeit with a disappointing lack of top end, but is also let down by the suspension, front end in particular, which Is woefully under sprung and really vague, and thats from someone who doesn't exactly push a bike hard! I did think the MT was a great bike though and I felt a bit cheated, or annoyed at Yamaha for not giving it better suspension, as it deserved it!
