Well..I have just about 5 weeks left to decide what my next ATC will be,I have got it down to a 200X/350X or a 250SX/250es big red. I would like to know a little bit about pro's and con's of shaft drive vr's chain drive,like durability,hard to find parts on the shaft drive? Do you get more life out of the auto or manual, given It will be all trail riding. I like the 250SX but I don't know what to look for when I go to buy one as far as play in the rear end.I know what to look for with the chain drive. Any advice on any of these trikes I would welcome. Thanks in advance..and wish me luck!
