Letting off or braking is the worse thing you can do and will usually only serve to exacerbate the head shake. Anytime that happens, gas it.
You're right.. not a thing wrong with the bike, except that it was designed for crisp turn in.Actually, maintaining steady throttle is safer. ANY additional bar input, even unintentional additions from twisting the throttle grip could prolong the wobble or intensify it. If you have your wits about you, slight application of the rear brake can help, but usually we are puckered too much for our wits to be working
This kind of thing is normal and to be expected on rare occasions. Unless it happens on smooth straight Tarmac, there is nothing wrong with your bike.
And a valuable, accurate opinion at that.I am a very firm believer that dirt bike riding makes you a much better road rider.
1. You get used to front and rear wheel slides and learn NOT to lock up and panic - or you fall off a lot.
2. You learn to modulate braking to achieve max braking without losing traction - or you fall off a lot.
3. You set up the bike controls and handlebar relationship so that you ride with relaxed arms and elbows out. This is key in being able to let the bike do its thing while maintaining steering, throttle and braking control. Elbows out and grip the tank with your knees to add your bodies inertia to the bike's turning moment . This is exactly why I spaced my bars closer.
And Nickpilot, I cant help but totally disagree with
I have ridden big loaded motard style bikes across the Australian desert and ridden KTM 990 Advs across Malaysia and into the palm oil plantations on the slimy red mud roads. If you get wayward, crossed up, tank slappy, doing nothing means you eat it big time. More often than not, careful throttle increase is the answer and sometime it is slam it open. If the front end is squirrelly or following a rut, the bike will peel out from under you unless you unload the front by opening the taps. Doing nothing will see you off. Like most things, you have to train your reflexes to do the right thing which is often the opposite of what your brain tells you.
Just my opinion.
