"Desert" cross-country riding and "dune" riding are two completely different things! You are an Easterner, so we will let it go this time.

Out TRX90's are excellent machines! Just air the stock tires down low, and they do great in the "dunes". They are also great in the "desert", and for trail riding, too. It's a do anything machine.
