Ill still keep my twin even when the V4 comes out. No point to sell it or trade it in. I think of all the bikes Ive had or even have now the 1299 Panigale is the one I want to keep. Call me nostalgic but I want to hold on it as a part of the twin history. Maybe Ill wait a year after the V4 comes out to see if it has any kinks to work out but if its trickled down technology from motogp then it could be proven already and its most likely been in the works for a while now. I'd trade in or sell my 2015 BMW S1000R for a Ducati V4 but still keep both the 1299 and 2016 S1000RR. My friends dad still has his 1990 851, 1993 888, 1995 916 and of course his 2015 1299R. Ive ridden his 851, 888, and 916. Love all of them. Im sure the V4 will be off the charts. Buts a twin is still a twin. Im sure most will agree with me here
