The measured values ​​of a Honda CBR 600 F show how different road surfaces in the rain affect the braking distance and the possible lean angle. The braking distance is hardly longer on grippy racetrack asphalt than on dry slopes. On the wet country road, the sports tourer needs 77 meters to brake hard from 100 km / h, and on bad surfaces it is significantly more. In addition, the possible inclination is drastically reduced.

In the dry, zebra crossings and other road markings are no problem, but when it rains the applied plastic is as smooth as a mirror. Therefore do not accelerate or brake, but simply let the motorcycle roll over them.

Cast iron manhole covers are slippery. You should therefore avoid them, especially if they are in a curve. Alternatively, raise the motorcycle up slightly and let it roll. The mostly short slides can be balanced more easily.

Bridge heels are often garnished with steel plates that hardly offer the tire any grip. Since you cannot drive around it, the general rule here when it rains is: do not brake, do not accelerate, but let the motorcycle roll without tilting if possible.

Blocked areas are not allowed to be driven on, so a lot of dirt accumulates there. For a motorcyclist, however, this means that if he needs it as an alternative space, banking and braking are extremely delicate there.

Bitumen strips offer little grip even when dry, but are really smooth when wet. Usually the steering twitches only briefly when one or both wheels roll over it. The wider and bigger they are, the sooner you have to go around them.

Driving in the wet and in the dark
Special conditions


Motorcycles ride well and safely

Rain is nasty, but dry roads don’t protect against slippery spots either. But darkness also presents motorcyclists with special conditions and frustration can also lead to dangerous situations.

Having a beautiful, winding road with the finest asphalt in dry weather to yourself – that’s probably what most motorcyclists dream of. Unfortunately, the reality is often different in our part of the world. And you can neither choose the weather nor the degree of filling of the streets, if you want to move a little further away from the garage at home.

Rain like in the picture above is nasty, but not a big problem with good tires and clothing. Dry and, thanks to the anti-fog visor, also with good visibility, we should still slow down, because the wetness and lower temperatures mean that we have noticeably less grip available. Road markings and bitumen strips, cobblestones and manhole covers are even more slippery than when it is dry. In addition, when we are wet, we cannot perceive such nasty traps as we may later even not notice an oil trail and the like. In dry phases, a lot of oil, dust and rubber abrasion is deposited in the pores of the covering. The next time it rains, these substances are moistened and act like soft soap. Shortly after the onset of rain it is therefore slipperiest, and after a day of continuous rain the grip has often improved again. The drawings on the right explain how the tires can interlock on the wet track.

Bends in the wet: drive soft lines

Bends that can be taken with easy turns in the dry require sensitive use of the accelerator and brakes in the wet. When it rains, the optimal line selection is even more important in curves than on a dry road. A defensive driving style and a smooth, rounded driving style are popular, which is good training for fine motor skills and concentration at the same time. The driving dynamics work no differently in the rain than on a dry road – with the crucial difference that processes such as accelerating, braking, turning and cornering should be much more gentle. If you turn sharply, jump into the iron or turn the gas hastily, you can suddenly overwhelm the tire grip on wet roads. Even when downshifting and engaging the clutch (tip: double-declutching!) You should go to work more gently; It is better to select a higher gear when cornering in order to accelerate smoothly and evenly from a lean angle with less speed.

Curves are pretty tricky when wet. Stop braking before the bend and turn in gently. Set the imaginary apex late so that there is enough space to accelerate gently. It is dangerous to live on the wrong line (dashed), especially since the asphalt there is often polished smooth by car tires and offers less grip.

In all of this, the following applies: stay relaxed. Especially when changing from dry to wet road surfaces, many people tend to tense up. And if you tense up, you will feel the motorcycle’s reactions later, maybe too late. In order to arrive safely in the rain, you should always consciously relax: drop your shoulders, loosen your upper lip, loosen your hands a little, take the tension off your buttocks. This is also possible while driving. In addition, maybe take a break and choose the pace so that you still feel comfortable in spite of the wetness. We recommend training under professional guidance, during which braking maneuvers and cornering on artificially watered road surfaces are practiced intensively.

So that the front wheel does not immediately slip away on the damp asphalt when braking without ABS, it is more careful to pull the brake lever and build up the brake pressure quickly, but a little more slowly than in dry conditions. Stay a little below the personal, trained maximum value. Important: brake hard at the rear. Braking decelerations of up to 8.0 m / sec² can be achieved on non-slip asphalt in the wet. This corresponds to a braking distance from 100 km / h of 48 meters, i.e. only around eight meters longer than the optimum in the dry. However, the risk of a blocking front wheel is relatively high, which requires lightning-fast loosening and gripping. Or an effective ABS, with which you can still get in fully in the rain or on a slippery road surface (see chapter “Correct braking”).

Wet roads: danger of slipping

The macrorough elevations in the asphalt store the rainwater, but only the microrough tips, which drill through the water film and thus establish contact, ensure a good grip and toothing.

In wet conditions, the grip of the tires drops dramatically, which means that significantly less lean angle is possible than on a dry road. However, it depends very much on the road surface. In a coarse surface with fine tips (technical term: microrough), the tire can interlock perfectly and even in wet conditions allows proper inclines, as can be marveled at over and over again in rainy races.

On the other hand, coarse surfaces with smooth edges (technical term: macrorough) such as cobblestones displace the film of water, but the interlocking and thus the tire grip are poor, and the possible inclination is greatly reduced.

Tire grip in the rain

The edges of the profile blocks work in a similar way. The rubber block is displaced by lateral forces and the edges are pressed onto the asphalt by the film of water. This is why tires wear out the most on the edges of the tread.

The tire tread is also extremely important when it is wet, as the water is transported to the outside via the tread grooves and a high pressure builds up on the edge of the tread block. This is the only way to break through the film of water and establish contact with the road.

Silica plays a major role in this context and is now added to many tires. In addition to other good properties, it ensures the necessary elasticity, even at low temperatures, in order to interlock with the micro-rough asphalt peaks.

Aquaplaning on a motorcycle


Motorcycling under special conditions


Illustration: Muller

When the water level is high, a water wedge forms in front of the front wheel, which is pushed between the tire and the road surface. If the water pressure is higher than the contact pressure of the tire, aquaplaning occurs.

Advantage for the motorcycle: Compared to the wide car tires (right), the motorcycle tire (left) has a smaller contact area and – more importantly – a rounded contour. This pushes the water wedge to the side, the tire pushes through the water front, and the risk of aquaplaning is reduced. The flat contour of the car tire, on the other hand, creates a wide water front directly in the direction of travel.

Riding a motorcycle in the dark

But even in dry conditions, not all tar is easy to grip, slippery road surfaces are not uncommon. Bitumen strips, for example, which become as smooth as ice in the summer heat, can turn out to be unpleasant surprises. And with gravel or gravel, you also have to cut the gas. Braking maneuvers on slippery terrain work best with ABS.

At night, visibility is difficult anyway, due to oncoming traffic, lamps, traffic lights and dark corners in between. With a scratched visor (right) and poor light, the night drive becomes a strenuous lottery

The edges of bends, where cars that cut corners never drive along, also offer more dirt than grip, which makes the choice of line, especially in left bends, demanding.

Excursions in late autumn should also be enjoyed with caution. Residual moisture and damp foliage in shady curves are sometimes as smooth as a mirror, and in river valleys bad banks of fog obstruct the view. The only thing that helps is to sit wide awake, but physically relaxed in the saddle and be on your guard. Especially in adverse circumstances, it is important to make sure that your eyes do not fall in front of the front wheel.

A strategy that is also recommended in the dark. The biggest problem when driving overland: the glare from oncoming drivers. Only good visual guidance helps against this blind flight, i.e. stubbornly stubbornly stare far ahead into the dark on your own lane, consciously away from the headlights of oncoming traffic. It is important to have a clean visor that is as scratch-free as possible, which, in contrast to city traffic, is not so easy to open on the country road.

Frustration can be a source of danger

And when the conditions are perfect, we often have to share the road with others. Does that sound any familiar to you? Even the motorway on the approach was packed, then Sunday column traffic on the favorite route, curve after curve passes without any real driving pleasure.

Beware, frustration makes you aggressive: If you finally get a free run after a long period of gamble, you should take a deep breath before you accelerate

We just can’t get past, and at some point it’s enough for us – according to the motto “now or never”, we plan to overtake.

This scenario is what accidents are made of in the best of circumstances. As difficult as it is, here we have to wait, wait for the right opportunity. Or take a break, choose a different route, drive the curves on the outer line as far as possible, or try to drive when not everyone else is doing it.

Above all, however, it is important to recognize when you get into such an inner state and then to consciously slow yourself down. Otherwise it can happen that on a dry road, with the best visibility and the finest grip, we simply dig into the next bend far too quickly, brake the car that we have just overtaken and still fly out because we are so frightened that we cannot release the brakes.
