When I accelerate upto around 100mph I get a small vibration in my handle bars and am scared to go any faster incase it gets worse. Why is this?????? Yamaha R6 2002

100mph!!! must be on a track day lol! its just the engine reving it nuts off I shouldnt worry bout it

The revs don't seem to effect it. It feels like the front wheel is kinda doing that shopping trolly thing!?

What do you mean that its doing the "shopping trolley" thing?

Im concerned because it could be you are experiencing high speed weave or high speed wobble..............

ok if it feels like the front wheel is weaving , a number of things could be.

front wheel bearings

front wheel buckled

head stock bearings

front tyre, it could be the balancing of it, are the weights still on the rim, or it could be the tyre its self.

is the bike new , or second hand , has it been in a crash, cause it could be a bent frame if its been crashed

are you sure its the front end thats moving {i know that sounds daft but} rear end moving could give you the feeling that its the front end moving .

are the tyres well worn?

look for flat spots on both tyres as well!

And check wheel balancing.
