![]() I'd blame whatever that dark spot and light spot are, it looks to me like there may have been a fluid spill of some kind and drying stuff used to clean it up recently, and it's still slick. Looked like your front tire wiped first but they both went at the same spot.

The surface does look like there is something on it, but on top of that you were still on the gas while steering. This will provoke a slide in situations where there was otherwise enough traction.
The correct action would be to roll off, steer, then begin the roll-on again. Even if that spot were slick, you should be through it before the bike falls down unless the back tire is spun up on the gas. The rear of your bike did swing out as if it slid more than the front, which is consistent with being on the gas a little too much.

My guess would be diesel fuel. Hard to get any more slippery than that.

I am very glad that you're ok. There are no other vehicles, objects or animals involved. Don't blame the bike, don't blame the road and don't blame the weather.

I have anecdote of two similar incidents. One to me, one I observed.
The first was in Phoenix. In July. I was making a turn lane left turn and almost lost the front. It was a slow turn, from a stop, but my front Moved. I didn't see anything, but honestly I suspected the road surface had an issue with the heat. Tar, oil, something. The second did not happen to me, I simply saw it happen. Random intersection, just starting from the light, and a bike came in to the intersection, going straight, and simply dropped like a stone. Completely lost the front and was done. I again didn't see anything obviously, it was like the bike was just yanked out from underneath this guy. One of the scariest things I ever saw. That sorta happened to me once, but I was making a left and it was pretty clear I lost the back end on that one. Bike slid out of underneath me. I zigged, it zagged. But this guy wasn't turning. So, mysterious.

Looked like sand on top of something slick.
Yeah, those getoffs suck.

If there is antifreeze on the ground it is very hard to see and super slippery

I pulled over and went back to look. Nothing to see at all. I did feel the road being a little slick when I walked on it and smelled diesel fuel. This road is used by heavy logging trucks and other semis and I concluded that likely there was a diesel spill by one of the trucks. The amazing thing is it was invisible. My Dad had a similar experience many years ago while riding to work. Getting on the freeway on a cloverleaf, down he went. Invisible, slippery, smelled of diesel fuel. I remember it like it was yesterday, I was sitting at the kitchen table eating breakfast and here comes my Dad riding up the driveway, handlebars pranged and nylon jacket tore up (he was on his Honda 305 Dream). No injuries to speak of except for a little skinned up here and there. Dan Last edited by bergmen; 05-01-2020 at 07:08 AM.. |

Question for the OP: Did you examine the surface near where you fell? Was anything off about it in the way people are suggesting?
The control input I commented on earlier would exacerbate a situation where traction was compromised. Rolling on the gas while adding lean angle will cause a slide at lean angles and cornering forces below what the conditions will really support.

Legs churning away as I slipped and crashed multiple times on my ass or face - all while enjoying the view of oncoming semi trucks as they dodged my bulging eyed meat-sack self. No bones broken, just a motorcycle that was a foot shorter and a lot of deep bruises all over my body. The other was in a slurry of diesel (again!) combined with sand and water running off of a construction site. This was less than 1/2 block from the TV station I was working at, after they failed to secure the hose filling their water truck. I smelled diesel and WHAM! down hard. That one broke 3 fingers and my thumb along with my left ankle. Busted the windscreen off the bike with my chin too. Rode it home after working my shift. What lesson did I learn? Pay attention to the road surface, if you smell diesel go to full alert mode. Last edited by islemann; 05-01-2020 at 09:59 PM.. |
