Hi I'm from Croatia in Europe and I'm thinking to buy conversio kit for kawasaki kx450. Have somebody try Russian brend Snowrider and how is it compare to Timbersled ? I plan to ride deep powder and climb high on the mountains so I'm looking for 137 model. Is it possible to ride it uphill with two riders and then one can snowboard downhil and other can charge on a bike ? Thank you for your answers.
