Of course it would be ideal (and certainly my strong preference) that the engines were assembled in the UK however, if the bike was 5-10K more expensive the criticism would have been all about a lack of affordability. It appears we can’t have it both ways.
The bikes were designed and are still ‘built’ in the UK - yes I know we’ve had the ‘made in England’ debate before!

Plenty of manufacturers (including Triumph) have engines/ bikes built overseas - Norton need to compete in the same market I guess.
The focus now is surely on just how good a bike Norton has built. If it’s a great bike then no doubt it will sell. Will the majority of those buyers give a toss if the engine was assembled in Honsur? Certainly wouldn’t stop me buying one.
