I just installed my vintage yellow cycra power flow plastics on my 2015. Kind of a pain at first and a little confusing. The airbox and radiator shrouds are the most troublesome. I ended up using the D-Ring as is for the top bolt and then just removed the D part of the other two fasteners for the airbox. The new red air intake guides didn't want to stay on at first but once they were secured by my radiator shrouds it all worked out. Loving it so far. I live 5 miles from the oregon dunes so the previous stock airbox would scoop handfuls of sand whenever I fell over (which happens often). I will give some more feedback after a few rides.
I can tell how mine were modified, as when the previous owner bought them from RedLabel, I don't think the graphics were out yet for the Cycra plastics. I can see a gap where the upper shroud bolt hole is, and they were also cut in half where the stock shrouds were in two pieces.
They're starting to get worn anyway, so when I replace them I'll have to get the correct set.
