Speed wobble at 95

[Gnasher]

I was riding my @ today on motorway today and kept getting speed wobble at around 95. I'm about 95kg and I had a top box with about 6 kg of weight on the tail. Does anyone else experience anything like this?

I've had problems like this on loads of bikes. It can usually be traced to:
Gripping the bars too tight (inducing the wobble yourself)
Incorrect tyre pressures
Worn tyres
Not enough rear preload or compression damping
The windblast catching on top box
Head bearings

Have a go at relaxing your arms, griiping the bars lightly. If that fails then whip off the top box.

If all else fails then slow down

Hope this helps

Check your steering head bearings, I reckon you'll find a bit of play in them. I'm 99% sure it will be this because mine is exactly the same because I've been too lazyassed to adjust the bearing up.

Another tell-tail sign is a slight knock if you go over a speed bump at any sort of speed.

Could also be worth tapping a screwdriver/pencil around your spokes as well, just to make sure they are all "pingey" and none are loose.

My @ will sometimes go a bit mental (normally if im changing lanes quickly) - usually anything from 95 upwards - this is fitted with tkcs which have slime in inner tubes - i thought this might have something to do with it upsetting the wheel balance

But probably because tkcs dont like such high speeds

Ive tried lightening my grip but it doesnt go away at these speeds, so i just slow down a bit

I have only noticed this since I fitted tkc's myself...... Iv'e not got any slime in mine yet. I was going to put some in at the weekend. I rekon the tyres are looking like the culprit at this stage. Iv'e experimented using a light grip so I can rule out rider error.
Has anyone else have experienced this with tks's?

all of my @s did this under load it was the only thing that bugged me about them must be down to the budget suspention

[Gnasher]

This is my 3rd @ now. It looks like I have been lucky up until now. Its a new one on me.

Don't do 95 mph - easy innit!

gnasher i agree firstly check head bearing but possibly your rear wheel is out a fraction the snail ajusters have probably had some stick in there time. take em off and clamp em in a vice back to back then round file em into submission and refit. use a wet string to check your rear wheel is in line then thrash it to within an inch of its life. if you still have wobble throw a brick through the bookmakers window. it will-not cure it but you will feel better.
