The R model needs a better quality rear shock.
The seat humps should be standard
It should come with 2 sizes of screen.
A rear brake would be a nice touch.
Maybe some integral master cylinder/reservoirs on the bars.
Colour scheme - Apes are always bonkers so I guess we have to live with it.
Power wise for a naked road bike it's got plenty, if I am honest.
Switchable maps - wet/road/track would be good if the engine got more poke.
mpg is entirely a factor of your right wrist. My wife gets 150+ out of a tank full.
I dont. :rolleyes
Seat - I have taken the "many pies" route to padded comfort. :dunno
Better range - ie a bigger tank as long as it still looks nice.
I would like the "factory" to include fully adjustable rearsets, variobars and a full "set-up" service in the price. So once it's run in you could tailor the riding position, suspension etc to your taste.
Looks wise I think the T is still pretty good, cans are a bit big, but the rest of it still looks better than most naked bikes.
