Looking forward to Roger's, Ian's. and others views from the event last night - I presume no-one is allowed yet to look under the bonnet or bootlid.
My initial view:
Wins: modularity for side luggage etc (presuming they can make that waterproof!);
+ new body design in total;
+ front wheel design although I'm surprised they didnt offer a (hugely expensive option of a) wire wheel alternative at the launch
Loses: lower engine torque at low revs will change this to a cruiser rather than a 3-wheeled bike? I saw some hints of them using the 3 cyl turbo (Super 3 Super?

) in future which would address that, although if a turbo fitted they could have used the 1l 3cyl turbo from the start...
+ side blades trailing edge looks clumsy being straight (angle or crescent indent might have been more in keeping)
+ front cowl-and-below looks too fussy (beware kerbs with the steering rack as your "bumper"!
+ that custom tyre is for sure not going to be easy to source!
Unknowns: where does the exhaust run - along the side / sill? Could get warm ...
+ did they fix the engineering snafus (BB mount, rear brake access, rear wheel bearings et al ) from the old car?
Annoyances: if they could "fix" the bevel box for this, why not for the 2012-21 model?
