What is the slipperiest stuff you have ridden on?

[Shorty]

The old Sunshine Skyway Bridge, running a Yamaha dirt bike with knobbies. 

[Huzo]

This thing.  With virtually no forward speed, the front end slid out on the smooth steel deck covered in water and oil and diesel fuel and Pete's yellow Griso dropped to the ground, well-protected by the cushioning my leg.  Sheesh.



Lesson learned, and I am now super, super careful whenever I'm rolling (or even walking) on the steel deck of a ferry.

So how was your Tassie trip then ?

[Muzz]

Oil, and lots of it. Went down so fast I can't remember it happening. I remember sliding a long way. I also remember three of us could not keep our feet to lift the bike up. We had to drag it off the road the best we could and get out of the stuff before we could keep our footing to lift it.

Wet cow sh*t is pretty slippery too.

Beautiful.

Clay for me though a mate would probably say the Kero
that leaches out of fresh Asphalt.

Without a doubt this 25 foot wet,algae covered walk way on my property.
Goofing around on my dr650 and tried to rear brake and turn and I
  went down fast. Wasnt hurt but sure did scare my mule!

When I rode my dirt bikes in Oregon, some places there was this light brown clay? that was impossible for anything to stay upright on.  There would just be  little round part of it but if your or your bike wheel got on it, you went down. 

But the fastest time I ever went down was my 1st time road racing on Oahu, Hawaii on a drag strip/road race track on my 305 Yamaha twin at the end of the straight away.  1 moment I was upright, the next moment I was laying on the side of my bike.     What had happened is between the air pressure I put in the front tire & the heat transferred from jamming on my front drum brake thru the spokes to the tube was enough air pressure rise to BLOW the metal valve stem off the tube!!!, which stopped me from moving forward real quick as I began turning left in the corner!   Luckily when it all happened I was hardly traveling forward so I didn't get hurt at all.  This was my 1st road race (`66) so I learned from it.

Black ice is pretty bad stuff and once you're on it you know.  It goes very quiet, etc. You can just feel it.  A long time ago a college friend of mine was coming into college when he was aware that he'd hit some.  "Okay", he thought, "so long as I stay upright and don't change speed or direction I might get away with this".  Then a cop stood out in the middle of the road and put his arm out for him to stop.  As my buddy was lying in the road looking up at the cop, the cop said to him "I just wanted to warn you that there's black ice here".  Luckily the bike was only a Yamaha DT175 so it didn't do too much damage.

Helpful cop, eh?

Did the deck/ramp also come with helpful 1/2" x 1/2" steel bars (sometimes at 45 degrees) welded to it about 6" apart to "improve grip"?

The fun part about these though is that you can't even slide your feet along for a tad more stability

I hate wet ferry ramps

[Nic in Western NYS]

Was riding last year in tomato farm country in western Buncombe County (yes, the name of this county is the origin of the slang term 'bunk' or 'bunkum' https://www.merriam-webster.com/dictionary/bunkum), and the front end got loose.  It was dry, hot, no tar strips, and I was going SLOW around a curve, like 10-15mph.  Went back to see what happened and there was very fine clay dust on the road which blew in from the farm.  Knock on wood the only time I've lost control of the front tire.

Tar snakes on a hot day.

Yeah.  Those suck.

Yeah.  Those suck.

 New Mexico 58 and 64 between Eagles Nest and I 25 are a tar snake nightmare .

Snow and ice on an RZ350 with Pirelli Phantoms on it,ill walk next time lol

[Muley]

crushed acorns and some not so crushed in the NC mountains
wet tar snakes
wet white arrows and  wet white/yellow lines
random sticks in tight turns
whatever that crap is they use on dirt roads in Alaska (calcium carbonate?) - when wet
the wet and oily steel grate in the middle of the 2 mile long Whittier tunnel
any surface at all when my rear tire is past worn out and I'm too cheap to buy a new one


these are not necessarily in order


I don't ride on ice

[Moto]

Strangely, in light of the "what makes ice slippery" thread, it was extremely cold ice that was most slippery for me. I'd been commuting on frozen snow/ice all winter so didn't see any problem when it turned 20 below zero (F). But when got a quarter mile from my house I found I could barely keep the bike upright even when hardly moving at all. I shuffled it around and went back home.

I guess there was another time when I didn't see a patch of ice on a city street corner. Both wheels shot left, but I stabbed my right foot down and saved it. So no big deal.

I used to commute at night to my job in high school, on ice, and kept up the practice on and off until 6 or 7 years ago. I quit because of the effects of salt on my bike.

Gasoline when the stupid fuel line crossover pulls apart and dumps fuel on your rear time.  Don't say I haven't warned you..

[Huzo]

I'm reliably informed that when I was 2 years old I soiled my nappy/ diaper while on a big journey to the front gate, about 35 metres as I recall, on my Cyclops trike, heavily loaded with gear ( pacifier/dummy and jam sandwich in the front basket, the end of the path came up damn sudden at the speed I was doing and she got a bit sideways.  Hit the front 2" drum brake hard at 4 kph and skidded inside the garment. That was slippery by all accounts and not exactly cold..Outt'a my depth on a big trip, nothing much has changed. Just sayin'.

[Brand X]

Mount St. Helens ash in 1980. Like riding on Grease..Ice storm is 1973-72 was about the same, but different..

YEP..... fricken cow pies.... left on the road when they do a drive from one pasture to another, not only very slick but they stink and stick to everything.

[normzone]

There was a member here who crashed on avocado innards , maybe someone can find the story - Dusty

That was [Semper-Guzzi] of Fallbrook CA, now code-named " Guacamole ".

As for me, frogs were gross but not slippery.

I did have a moss go-down, six inches of slow moving water over a concrete stream crossing - I got no further than one bike length into it at low speed and it was all over.

While I was moping an onlooker told me not to feel bad, the day before the same spot took a full size truck with camper shell off the road and it had to get winched out.
