Why do Motogp bikes wobble?
The rear caster is much longer, feet rather than inches. Casters, as we can see any time we push a supermarket cart, are capable of oscillation, the castering wheel swinging rapidly from side to side. Motorcycle engineers call oscillation of the front caster “wobble” and oscillation of the rear caster “weave.”
How do you prevent a tank slapper or speed wobble?
Usually you can safely halt a low-speed tank slapper by simply leaning back and accelerating. You can also experience speed wobbles under deceleration, especially if you have only one hand on the bars. They are usually not as wild and can easily be corrected by releasing the brakes and adding a little throttle.
What causes motorcycle tank slapper?
Most tank slappers happen when the front wheel breaks traction, becomes airborne or somehow leaves the track of the rear wheel, causing the frightening chain reaction.
How to control a motorcycle with a tank slapper?
However, few riders understand how to best control a motorcycle that is already experiencing a tank slapper. When this occurs, it is advisable that you relax the pressure on the handlebars by holding it lightly and allow the pressure to settle down.
How do you fix a tank slapper?
If you are under deceleration and have only one hand on the handlebars, you are also more likely to experience a tank slapper. These are however not as wild and can be easily corrected by lightly holding the steering with both hands and adding a little more throttle.
Why do old bikes wobble so much?
What the old videos don’t point out is how these speed wobbles were much more prolific on old bikes because of their thin forks, basic suspension, low-speed-rated tyres, heavy wheels and poor aero. Speed wobbles are not as prevalent on modern bikes with better suspension, tyres, lighter wheels and better aero.
