Ive got a 600 SS. Basically the same bike but with a smaller motor, single front disc and single exhaust.
It is my first bike after a 250 and I think its a good step. The 900 will obviously be faster than mine and mine is about the slowest 600 sports bike you can buy...but mine is still alot of fun. Not the fastest bike but still faster than just about all cars, and its very rare for me to need to wring it right out to go as fast as I want it.
Size and weight wise (mine is 172 dry, 900 will be a couple more) theyre very similar to a Hyosung so it should be a relatively easy step.
Ive only had mine 6 weeks and 1200 ks so I cant comment on reliability (has been fine so far).
I wouldnt worry about people saying theyre slow, itll still be alot faster than what your used to, who cares if its not as quick as a Jap 4 cylinder sportsbike.
Plus its got the ducati noise, nothing else sounds like them

(that I know of )
