Operating the clutch pushes the clutch pushrod forward and hence the pressure plate into the flywheel and in turn tries to push the crank forward. Noisy front bearing?

might be worth checking that the engine mounting bolts are tight, that can exaggerate any noises
my bike thuds a bit under load, but its better when you rev the nuts of it
an Italian taught me that
this is a thing worth knowing
it makes it go faster
and it makes the dials whizz around which looks pretty

It sounds like Mike is suggesting the front main bearing but I would be surprised if it is that on such a new bike. On the older bikes this is a plain bearing which any pressure from the clutch on the crankshaft would have little effect. I am not sure what type the main bearings are on the Breva but would be surprised if it is that. Have you worked out where the noise is coming from?

It could be worthwhile to check the oil pressure,at a dealers If you don't have the gear to do it at home.Any excess radial clearance between the front main bearing and the crank would result in a drop in oil pressure.I don't suppose this is the problem but it would be beneficial to know that all is well in that department and eliminate one possibility.
