High Speed Vibration
Posted: Fri Nov 06, 2015 11:13 pm
Hi,
I am noticing a fine vibration coming in just before 80kph in my 2013 PCX 150. It changes pitch when the bike suspension goes up and down slightly. Feels like its more in the rear end. I also have a slight clunk if i push down on the seat and make the rear shocks move, i have new YSS G Euro shocks. The clunk isn't noticeable at speed and everything feels good. I m not sure if its related to the vibration. I took it to Honda and they pulled the storage box out and checked the shock mountings and all was good. I have spent ages trying to work out where the clunk is coming from. It appears to be just as the shock moves down and is louder if i push down quickly. Its not the basics like the seat, but i was thinking it might be the shock valving? I can't see or feel anything loose.
Any ideas??
