Hi there. I am new to the group and have an MP3 500 sport 2016. over the past few months I have noticed that my bike moves around a lot over bumps and cracks on the roads. it feels very unstable and not great to ride. any ideas would be greatly appreciated please.
thanks Francis (Puddsy)

Hi there. Bike is serviced about every 2000miles and has just hit 10.000miles. Tyres are good although not sure what make they are lol. Bike was okay until a few months ago now just does this weird movement where everything gets very lose and feels very unstable. Also front end moves around a lot going around bends.
Hope this helps?

Sounds like time for a basic pre-flight check to see if anything is amiss.

Pull it up on the center stand and give the rear wheel a wiggle. Up and down? Left and right? Should only spin and not wiggle.

Then either jack up the front or have someone lean on the back to lift the front. Same game, check each wheel. In/out, up/down, left right. Check for wheel bearing wobble, any looseness of the vertical fork tube bearings. Also pull the wheels in and out (pigeon toe'd?) to see if there is any looseness of the tie-rod between the wheels.

I find tyre pressure always critical to some road conditions

What exactly do you mean by moves around a lot? Side to side?

Hi there. Yes exactly what I mean the whole bike seems to move around from side to side. Steering feels heavy to which it never used to. I have checked tyre pressures regularly and also looked at wheel bearing play. So far all that seems good. It's strange to say that two wheels feels far more stable and secure than the three I have now lol.

I can't help you with your problem but I think I know the feeling you are talking about. This stretch of road on my ride has grooves in it parallel to my direction of travel. When I hit the section the bike feels like it's on ice, sliding from side to side a couple of inches. It feels like I have no contact with the road, and it is pretty unsettling.

Check for the 'Notch'. When the steering bearings in the front legs get a 'notch' in the straight-ahead position, the steering can feel very weird. The first symptoms are when it becomes dodgy to try to filter, as it's hard to keep the bike going in a straight line. When it gets worse, you'll find it's tricky to steer with confidence at speed around curves.

If you have some scrap Contiboard (melamine covered board) handy, then cutting four squares can make a 'lazy susan' under each front wheel at the same time. Then turn the steering through the centre position a few times - if you can feel a small 'click' in the centre position, then you have the notch. It's an MOT failure - so get it done ASAP if this is the case for you.

A very good temporary solution is here:
Short term fix for "notch"? - It works... and this can become a long-term solution if you get the steering bearing special grease bolt and grease up the bearings.

Or you can take it to your dealer and cough up upwards of £500 to get them to fix it - again *if* this is your problem.

It could also be all the things mentioned in the above posts, including the swing-arm bearings.

I would go for the notch problem as it has has all the hallmarks of over tight steering head bearings( on a conventinal motorcycle steering head). Also if the rear tyre (citygrip) is quite worn i found the fuoco wandered around quite a bit a new tyre sorted most of the wandering and new quality rear shocks cured the wandering .
