Yamaha sleds are starting to make their way to dealers across the North American snowbelt. Tucked inside each sled's owner's manual is a notation of the unit's dry weight. Here are the stats on a selection of new models for 2003.
RX-1: 558 pounds
RX-1 ER: 564 pounds
RX-1 Mountains: 589 pounds
SX Viper Mountain: 515 pounds
All weights were measured by the factory without any fluids.
