Thanks for your advice JimDirt, it’s only the front end bouncing, and I haven’t hit any potholes so my suspicion lies as you suggest with the front rim or tyre. I will jack the bike up, give the wheel a spin and see if there’s anything out of shape going on.Welcome to the site !!
Is both the back and front bouncing ???? , did you happen to hit a large pothole or something ?? , I would expect it to be a wheel (or tire) out of round or out of balance causing that , maybe check to see if the spokes have not come loose and that is causing it ......
Only so many things it could be and it all relates to the rims and/or tires , if you can put the bike up on a stand so the wheels are elevated and spin them by hand (to get a good spin on the rear you may need to remove the chain) , or very carefully start the engine and put it in 1st gear , let out the clutch slowly and see if the rear wheel bounces or wobbles , which would indicate out of round or balance or a spoke issue , the front you can just grab and spin as hard as you can to get it spinning fast to see if there is anything going on there ....... But that is what I would start with ....
Thanks for that, I will investigate and let you know. If I don’t find anything unusual it’s going in for it’s 1st service soon so hopefully the dealer will find the cause if I can’t.The front will bounce around if somebody didn't put oil in the forks or it is at a low level. Of course it will need a bump or out of round wheel to get it going.
Not something that happens often so just a suggestion.
New bikes often lose spoke tension so that will be a good place to start.
Use the right size spanner and if you haven't tensioned a wheel before there are several good articles about it on the net. Thought there was one on the How to page but don't see it.
