Inclement Weather

Alright, so how does the weather effect your riding?

I saw no less than three incidents on my way home from class today and that got me wondering. (It's sleeting here in Northern Virginia)

Witnessed a guy on his Harley Fatboy driving in this mess, nothing happened to him other than he looked quite pleased with himself.

Just before Christmas, I got out my Daytona to go to work as I always do. It had frozen overnight and the ground was frosty. One hundred yards from my house I hit some black ice. You can't see black ice, it's invisible. I wasn't braking or leaning or accelerating, but I was shifting my weight slightly in the saddle. I was doing 10-15 mph. The bike went down - straight down, no chance of saving it. The drop did £2,800 worth of damage (5,600 USD).

The average motorcycle tye makes about one-and-a-half to two square inches of contact with the ground. That's not a lot. That small amount of tyre (x2) has to generate all the traction you are going to get. It doesn't take much to disturb that and when something does, what you have is a hazard.

At any time, wet roads can be slippery and reduce traction. Braking distance doubles in wet conditions. In a heavy rain you could end up hydroplaning where you have lost contact with the ground altogether and are skimming along on a layer of water. You can have a slide and deck your bike on wet metal drain covers and wet white lines - both very slippery.

In the autumn the odds go up. You now have to deal with wet leaves, wet mud, and the patches of loose gravel washed out of the banks by rainfall. Fog is great, because it turns idiot cagers into idiot homicidal cagers.

In the winter, you have frost, snow and most particularly black ice to add to the excitement. You also have loose patches of salt that the authorities kindly lay down to keep you 'safe.' Road surfaces can break up very quickly in winter conditions if not attended to. Is that just a puddle up ahead or a three-inch deep pot-hole filled with rainwater? And then there is the cold. It is easy to get hypothermia on a bike when the weather is cold - it depends on your gear, your constitution and how much fat you carry. As hypothermia sets in, your concentration plummets, your reactions go into slomo, and your safety margin disappears.

Sure your guy on the Fatboy might have been pleased with himself. He might have been pleased with himself all day and the next, but the chances of his not being pleased with himself at some point in time are much greater in frosty or icy weather.

Riding in poor weather conditions can be done; some guys do it for years before they have a serious spill. Yep, it can be done. But when the going is poor you need a well-developed ability to read the signs, a lot more riding skill and a fair bit of luck.

For me safety is most important, followed by the fun factor.

I've been able to safely ride only 3 times this winter. The last time the roads were dry but when I got to my destination my usual bike parking spot had somewhat of a snow bank, which I had to break apart with my boots and then park around! Later that day a cheery scooter parked beside me. Great minds think alike!

I pay attention to rain and snowfall, and the temperature. If the road is dry and no precipitation is expected, then ride (either above or below 0C/32F). If it's above 0C and wet, try to figure out if the temperature will be above zero (ride), or below (maybe not) on your trip back home. Note added to the usual cage incompetence, drivers are not expecting a bike on the road, so light yourself up like a Christmas tree or a pink bunny.

Most weather reports have a dew point reading. If there is precipitation in the air and the temperature is below the dew point, this wetness will fall to the ground. If the ground is also below 0C/32F that wetness will freeze and you will get black ice. If you ride and hit black ice your fun factor and your wallet thickness will significantly go down.

Sliding out and doing £2,800 worth of damage (5,600 USD) is not what I consider fun. Ouch. sv-wolf, sorry about your crash.

Freezing temps + falling precipitation means I do NOT ride. Two wheels on ice/snow is a very dangerous combination.

I don't ride if it rained previously and temps have been low. I'll pay attention as I drive my car to see that puddles are gone on my route. A surpise frozen puddle can really wreck your day (pun intended).

I'm south of Baltimore, and I was amazed to see a HD heading along RT100 just before lunchtime. Just as the snow flurries were about to turn to sleet.
