899 has been out for over a year now and still only in the launch colours. My money is on a dark stealth next and perhaps a corse edition?
I doubt they will do a single sided swing arm version, price for 2015 is £500 more than last years launch price, single sided will add another £500 or more, plus the fact they are launching 1299 & an S version too. I think colour schemes or any other alterations are out of the question IMHO
Can't see the single swing arm, ever. I do think the black is likely early in the year and the white being dropped.
