i was thinking about buying a 650.Has anyone had any major probelms? Do they they have the bottom end as a 400ex?

 

I HAVE'NT HAD TO DO ANYTHING BUT HAVE MY BELT TIGHTENED AT 750 MILES, THE DEALER SAID THIS WAS REAL GOOD AND THAT WAS PROBABLY THE INITIAL STRETCHING AND IT MAY NOT NEED IT AGAIN FOR A COUPLE THOUSAND MILES. SO THEY SEEM TO BE HOLDING UP GOOD. REMEMBER THIS IS A FIRST MODEL YEAR SO THEY WILL HAVE A FEW BUGS TO WORK OUT BUT KAW. SEEMS TO BE STANDING BEHIND THIS QUAD. YES IT WILL OUTRUN A STCK 400 EX AND THE TOP SPEED IS ABOUT THE SAME TO. AROUND 65 MPH. GIVE OR TAKE. I JUST GOT OF MINE ALITTLE WHILE AGO. HAD IT 63 MPH.
