I was thinking of upgrading my Girlfriends trx 300ex to a DS650 and i really havent heared much about the pro's and con's. How good are they for trail riding or racing. How easily are they to handle cause she's not that strong. Plus how whellie happy are they. I know there about 500lbs but they make around 38 hp. How soft of a ride are they cause my Raptor has a really stiff shaky ride and She doesnt like it. How durable are they because i want them to last for a long time.
