Your motorcycle will go through various "zones" of oscillatory stability and instability as it accelerates up to its highest speed. you might even compare this to musical notes or octaves of relative vibrational resonance.
Steering dampners are made to help with this problem as the main dampner ( you ) cannot always handle the correction of the vibrations.
The best advise is to slow down, as this can be a fatal but also unavoidable occurrence and even though the problem may go away with more speed the best way to take the bike out of that particular resonance range is to back off.
The tread of your tires could also be a contributing factor, particularly the front one. different treads have different resonant properties.
In addition to above, get both wheels statically and dynamically balanced. It reduces wobble, increases road holding and reduces tire wear and rider fatigue. Check forks and swing arm for correct operation. A lack of fork oil and too much side play in the swing arm are sources of vibration. Check panier box lids are fitting properly and are locked. Lid 'chatter' in the wind can be one of those resonances mentioned above that sets wobble off.
If your motorcycle is pulling a sidecar or has a handlebar-mounted fairing, this will increase the likelihood of a steering wobble under certain conditions. The wind wash from driving near a semi truck can also cause a steering wobble.
Although many things can contribute to starting a wobble, they generally won't happen if your steering head bearings are properly maintained. Test your steering head bearings by accelerating to 50 mph or so on a straight, smooth road on a calm day with no oncoming traffic. Close the throttle and remove your hands from the handlebars. If your bike's steering seems to pick a direction and stick there, your steering head bearings are too tight. If there is any wobble at all, your steering head bearings are too loose.
yes, but it is the gear ratios that affect the overall speed
Though it highly depends upon motorcycle class and engine but normal speed is about 30/40 kmph.
Instantaneous Speed
you have to have good balance. other than that, that's all i can say. sorry
Unbalanced wheels or a bent track rod
the posted speed limit
It is a speed demon
Top speed is 140mph
Motorcycle mph varies from make & model. The average speed of a motorcycle ranges from 180 mph up to about 395 mph.
varies based on the type of motorcycle and the engine size
A 200 cc motorcycle should do around 75 mph.
Suzuki hayabusa it is the fast motorcycle in the world. This motorcycle looks heavy but it is light and your ride is with ease. This motorcycle has fast speed and must be handled carefully when riding.
