I bought a sled again this year cause a few trips out in 2ft+ of POW on the bike sucked. Hard to get around, sled way more fun in those conditions. I also like the challenge aspect of riding a sled sometimes too. However, i've put 6 hours on my new Axys this season, and 25 hours on my timbersled. The conditions just lean so much more heavily to a snowbike. I can't say which is more fun, depends on the day. I love exploring on the bikes. that's the best part. And racing through the woods. Super fun.
Especially in WA. Cant swing a dead cat without hitting a tree or 10 here!
Having lived/ridden in a lot of western states, bikes shine in the PNW for several reasons.
Low altitude doesn't suck the life out of a 450.
Trees, gullies and steep is like 90% of the riding.
Wet heavy snow means not as many stucks on powder days and even though stucks are worse in heavy snow, bikes are 10x easier to get unstuck.
Compared to AK which is probably the most polar opposite riding with the rest of the mountains somewhere in between, except for altitude.
Wouldn't really want a bike in AK.
Wide open, not conducive to lower track speeds of a bike. And its funner to powder turn your way across powder fields than pinning it on the bike and trying to hold 4th gear until you hit a hill.
Cold as shiiiiiit a lot of the time. Not so much fun on a bike.
Miles from nowhere means more tools, survival gear etc, easier to pack on a sled.
Never ridden a sno bike at high alt, like 10kft, but the way it tames stock 800s and big bore bikes on wheels, I'd be back to mod machines. (Another thing I like about WA and AK. My "weak" 2012 stock Pro pulls like my mod M1000 in Colorado.)
I will be doing both for a long time, I predict. Different conditions make each machine shine....and its not like riding a sled sucks!
