Ive rode renshaw many times on my snow bike and no issues with fuel. i pack the 3 gal mountain addiction can and my tank on my yz is 2.3 gallons. I have had to borrow alittle fuel before to get down but rarely. Its abit of a long trail ride into renshaw but long as its got some decent snow coverage good to go. When trail is whooped out you can ride the trail edges or just blitz the whoops passing all the sleds lol .Spring is only time ive rode bad trails then it can be sketchy on bike lots of icy or bare trails rocks and crap and open creeks just have to take it easy on that stuff. Rarely do any sleds make it down before the bikes in our group anywayI am also thinking of building a snow bike. I have only been sledding for a couple years, but have been riding dirt bikes for years (summer and ice racing). I do have a couple questions. What are guys using for boots? Also what range to guys get on fuel? Again only sledding in the mountains for a couple years we usually just ride Renshaw. Am wondering if you would just have enough fuel to ride to the cabin play around a bit then head back? or can you make a day of it?
