Yesterday I went over to a friend's house to check out a 916 he's semi-trying to sell. It's a '95 model and my M900 is a '98. I'm trying to come up with a good qualitative description of the differences between the two aside from the ergonomics. My monster seems to have a bit more low end grunt and with the open air box plus Remus exhaust it sounds meaner. The 916 sounds a bit more refined, doesn't give up much on the low end and when it's comes on the pipe it yanks pretty darn good but it makes this different noise than my Monster. It's definitely not a noise like a Japanese I4. Could it be that the engine is just a tad smoother than the Monster? I don't know. It's as though if my bike were a good running well tuned 427 V8 then the 916 would be a race tuned 289? That was the first time I've ridden a Ducati 4 valver and at the time one of the thoughts was that it sounded exactly like the footage of that guy riding a 916 at Nurbergring. (Duh) What a hoot!
