During a fast decent this morning i thought i was going to die! The bike started to wobble and i thought the front wheel was going to come clean off! I must have been pushing 65-70kph at the time.....i really thought i was in trouble.
Anyway, hit the brakes (in hindsight this is probably not such a good idea) and came to a stop. I checked the bike for loose bits but nothing! The bike had just started to wobble because it felt like it.
I don't want that to happen ever again, it was far from pleasant! So, can you lovely people please tell me a) Why? and b) What i can do to prevent it?
Thanks in advance
A shaken up GaryRoberts!

Perhaps at your speed the front wheel did the same. Maybe keeping a little more weight over the front wheel with your position on the bike would help. Glad to hear that you're ok, though.
If I've just offered advice that will actually make things worse I await to be corrected by the masses
That sounds kind ball slappingly scary!
Dont let it get into your mind that it will happen again. Get on the beast and nail that descent aghain soome1
Sounds proper scary!
LOL
I can imagine its very frightening.
Interestingly at the same speed.
Nice sensation isn't it!

This crazy fool makes it happen on purpose. Looks like it can stopped by standing out of the saddle though as this changes the resonant frequency of the bike.
So, relaxing your grip on the bars usually sorts it out. Takes your arm mass out of the system. Also, a loose grip then has a damping effect.
Hitting a bump on my Dolan at about 55kph or so can sometimes set her off. Relaxing the death grip has stopped the wobbles (and ensuing brown shorts) every time.
Scarey and basically not a lot you can do other than grit your teeth and ride it out as braking too vigorously can cause a 'steeping off'.
