I"d love a 250 SX.. in deep mud with manual clutch can be a trailprotrailprotrailprotrailprotrailpro ( not that anyone ever need to this ! > but if you have to GET OFF to make it over train tracks, or in VERY DEEP mud , a manual clutch CAN be a trailprotrailprotrailprotrailprotrailpro, not always tho .LOL.. )
Personally i'd go with the SX, but i saw a few pictures of a 350 X on atvconnection.com that made me drool and gave me heart irregularities today !
