Is this Monster 900 good bike to buy?

[Bun-bun]

Sounds like fun - they had great color schemes - post pics!

You'd think so, but actually the 900 only made 78 hp and 75 Nm where the 695 was 73hp/61Nm and 696 is 78hp/69Nm

I really wasn't as concerned with HP and torque as I was with the clutch. The dry clutch takes some finesse to use well, and a noob won't have the right reflexes and could get into trouble.
Anyway, he says not a noob, so MPTH.

Those numbers don't give 100% of the story.  Look at the torque numbers to give you an idea of the character of the 900.  While it's only got 6% more HP than the 695, it's got 22% more torque - it's that torque that give the 900 it's grunt.  Also, it's just something about how/where those mills make power that's just a little different. 

Add the fact that the output is measured at the crank on the newer 695 and 696, and at the wheel on the older 900s.

Let's not confuse things with the facts.....

Well, really - we all know that the 620 is the least beginner of those bikes... I mean, really - it'll do 140 and 0-60 in 2 seconds flat..

Yes but only if it's the Caprex version

Sorry...

I don't know what came over me.

To the OP...

the venerable 900, whether carbed or FI is a great bike IMO.

The M900 is an awesome bike.  I <3 mine very, very much. However, YOUr m900 was obviously crashed (tank damage/broken lever= typical monster crash outcome) so I would seriously take it to a reliable mechanic to have everything checked out, for safety's sake, as well as assessing the parts your seller said needed replacing.
