I hope you didn't take my comment the wrong way. There is no way I'd condone riding in those elements with that large of moto. I wasn't planning on getting into snow on my ride and just did near the pass. My point was really to emphasize that the weather in WA is unpredictable and how it can change at high elevations even in late June.
This is the worst bind I've been in while in snow but on a light weight dirt moto.. sketchy stuff. My friend was pretty excited but we still had his moto 100 yards down the slope and had to get it up to the pass.
Lol, if I was on a lightweight dirt bike with good tires, I'd probably have ripped that up, as long as I was pretty sure that there WAS a dirt bottom under the snow, i.e. not crossing some crevice packed with snow and ice. I regularly rode some of the California deserts where the dirt was like Talcum powder; can't be all that much different.
In fact, one my more painful dirt riding spills was when I was riding in a group of six, three youngsters maybe 9 to 12 years old, along with their dad's (all neighbors on our block). I was bringing up the rear, we were running through a wadi, and the lead rider decided to turn and go up and over the berm. Right before I went over the top, talc sand was kicked up and I was blinded, riding into nothingness. Just as I crested the berm and about to come down, I saw thru the dust one of the kids and his bike sprawled perpendicular to me. He had fallen, and was up against the berm. I was just about to crush him. I reacted instinctively, blipped the gas, and prepared to lay the bike down just ahead of him, again, in absolute blind-darkness. Well, the drop was a little more than I had expected, dunno, maybe 15 feet, so I essentially dropped from a jump down into dead air, hitting the ground hard on my left side. The air was knocked out of me, and was on the ground for a couple of minutes before I could move. I (probably) broke a couple of ribs and jammed my left shoulder badly enough that I later couldn't lift my left arm. I rode back to the camp with one arm, fortunately, my throttle side.
Of course, rather than being a hero, my (then) young son said he was deeply embarrassed. I guess from the other side of the berm, with clear visibility, I looked like a clown. The other dad's didn't try to help me, the father of the boy didn't bother apologizing or thanking me for not killing his son, and ... we never road with those guys again.
But anyhow, as long as I have good traction and can muscle the bike out of any trouble I get into, I'm not too worried about sand or snow (though I also, wouldn't go out of my way to find either - I like trail riding actually). On the 700 lb Beemer, ahh... yeah, no thank you. I've already done my "stunt riding" on dirt bikes, and I usually hurt for 6 weeks afterwards. 😏 That's a young man's gig. I hurt for 6 weeks last spring when I was practicing slow speed maneuvering on the RT, and (I think) accidently stuck the clutch in the corner, resulting in an authentic looking "rookie tip over". I bounced down, landing of course, on my right elbow, jamming my OTHER (right) shoulder and ribs. Fun times! I can't wait to go out and do it all over again, next spring. 🙄😖
