As the weather is nice I thought I'd have a quick look again today. So I can definitely confirm the bike has been lowered at the back as it's sitting on longer third party dogbones as per the pic. Although it doesn't look like they've balanced it at the front as the front forks are right at the top of the yolk. No cracks, smooth movement everywhere and no leaks on the forks. I plan to take it to a garage tomorrow but I still haven't got a clue what's causing it.

How much of the fork leg is protruding above the top yoke?

Seems to me like it's been lowered (too far) by dropping the yokes on the fork stanchions.
Yup.
First thing that sprung to my mind and I don't know st about bikes.

It might be an optical illusion but that fork leg nearest the camera does seem to be clightly curved frown

As per pics, no protrusion from top yoke at all. So although rear has been lowered, there's no indication the front was lowered to match. I think it's very unlikely the garage would have swapped the suspension from another model as the cost would have been mad. Also previous owner used the term of them lowering the seat, hence the rear suspension.

First thing i noticed and i hadn't even read what the pictures were about.

Edited to add, holding a bit of paper up to the screen along the fork leg it's not looking too good....

Looking in the flesh I can't see it myself, I think it's the way the photos came out. I'll see what Honda say tomorrow. Unless anyone has any recommendations for a decent independent in central London?

I think it's more likely that they cut down the spacers fitted in the forks and / or fitted softer springs.

If it has a centre stand and you can still get it on it, do the forks extend much further? Or try putting the front brake on whilst sitting on the bike and pulling the front end up.

How about calling the dealer that did the work for the previous owner?

Even if they had done that, the forks should hit the bump stops before the mudguard catches on anything, surely?

This is exactly the thing I can't quite get my head around.

Those pics really look like the forks are bent.
Have you bumped it at all?
Did you buy from a dealer or private?

Private, but I've had the bike since October and until this it's been perfect. Been to the dealer for minor things and they've done a health check and not flagged anything other than consumables. Haven't bumped the bike at all.

It looks bent.

tbh I'd also be getting the fairings off and lookiing to see if there is any sign of frame damage.

Yes I was thinking that too and it should hit the bump stop before becoming coil bound, but something is up.

If the fork bushes are worn, head races likewise and the mudguard bent slightly, it might be enough.

OP, get a tape measure and measure the length of the forks uncompressed. Get someone from the NC forum with a stock bike to do likewise.

I’m new to motorbikes, but is it possible they’ve altered the rake/steering angle?

Is it definitly an original mudguard or an aftermarket one that's a bit longer than standard?

I had initially though that either the frame and/or fork must be bent. Looking at a picture of a new one though, it appears that the rear of the mudguard will travel towards exactly that point (trace a line at the same angle as the fork tube).

I'm now wondering if it's a result of messing with the fork internals to lower the front. However, the standard bike would have very little front end travel if it stopped before that point. Maybe it really is so close that a slightly bent mudguard is all it takes.

Well looking again at the picture of the whole bike on the previous page, the front had definitely been lowered.

Given that the forks have not been dropped through the yokes, clearly they have been modified in some fashion. So start there.

I thought that picture was showing the bike in its 'jammed' position.

Yes it is.
