It looks to be a nice bike. I'm not familiar with the model, but it's pretty much an Amp linked 4 bar which IMO is the best all around rear suspension out there. I had a Specialized FSR team downhill frame with that rear end on it and it worked great. The rear shock looks to be a Fox TC or RC with at least rebound, I don't see the compression dial on the piggy back but it's still a good shock. Marzocchi forks are great, once I tried my first one I never went to any other brands, I had two Z-1's, a Monster T and a Shiver on various bikes. Hayes front and rear with 8" rotors are a part you will never need to upgrade. I think those are Truvative cranks, but does that thing have more than one front gear? I see the front deralier(sp), if you are going to be hitting some pretty nasty terrain, A single fornt with some sort of MRP ish chain guide might be in order.
Considering where you're from, you will have great terrain to really abuse that thing. I spent one year racing some of the Norba Nationals in the US and alot of the fast guys were from your neck of the woods.
Advice, keep your weight back, learn how to spin good because those bikes will bounce all over the place if you have a sloppy spin. LEARN HOW TO FALL, no joke.
