I have the base 1299 and have done lots and lots of mods to it. All cosmetic with the exception of the steering damper exhaust, rear sets, doing a 520 conversion now and a 41 tooth sprocket and rapid bike. Within the next few weeks Ill be doing the front and rear suspension. Did lot of mods to my 2015 S1000R , more than I should have which include a full 2018 Akra system and the 2018 Akra gp can along with rear sets, rapid bike + my tuning , 520 42 tooth conversion and much more. And did lots of mods to my 2016 S100RR. I love the 1299 and will keep it. Love the weird look of the S1000R and enjoy riding it when I want a more relaxed ride. But once I pay off the 2016 S1000RR or paid it down enough Ill either sell it or trade it in for the Ducati V4s or the new 2019 Aprilia RSV4 that they say is coming out. But Im leaning more towards the Ducati V4s. Would love to have the previous generation Ducati sitting next to the new generation Ducati
