They
I really can't see where the £42k has gone tbh. They "inherited" the V4 when they bought the company. The previous reasoning for the price tag was its a bike developed at the TT over several generations of race bike etc etc blah blah blah. But TVS have done none of that, they've just picked up where Norton left off, essentially with a bike that was 75% there. For me, it's still a beutiful bike and if the TVS version rides like the Donington version, then the chassis will have excellent road manners....hopefully they've tuned the fueling though, as that was pretty "raw" (a term used by journalists when they're saying something aint finished yet).
TVS do need to improve on the visuals of their welds and polishing though. Skinner designed the fairing to cut away in key areas to highlight the welds, as they were worth showing off. It looks as though some of that detail and thought has been lost.
First picture is a V4ss I currently have in for work, second picture is a Brummie-Norton V4 weld.
