Can someone give pointers as to what would be vibrating at 4000-4500 rpm while in motion? It seems like it's coming from up front around the steering neck. Any help would be appreciated. Thanks

have you check the tire's pressure. if not, do it when they are cold.(front 36 psi/back 41 psi)

My apologies, it's a rattle/vibration as if there is some small part loose does not affect driveability still a smooth ride!

It could be loose plastic, a very common problem.

It could also be the brake pads, particularly if the pad springs have been removed. If so, the noise will go away when you pull the lever and come back when you release the lever.

Look for a loose or lost bolt.

Thanks guys, I found the windscreen was loose but there is still something else loose. I'll remove the front fairing and check everything over the weekend.
