Yeah I have A 570 and I couldnt come up with a bad thing to say about it.Its by far the best bike I have ever riden.
As far as handling is concerned it what your used to and if thats a Jap bike then a Euro bike might not be for you.
Ive had my bikes suspension done both back and front to suit the kind of riding I do which wont suit someone else.
Ive had no problems with it at all, it has always started and got me places my other bikes would have had trouble with. The REKLUS cluth helps alot.
As for the Fro testing a 390 and not being as fast as a DRZ 250 what a load of B*&^S#$T who sponsers the show, So why would they say a berg is better or faster, it would only insult there sponsers.
Cheers
