Ultimately it depends on what you like. I just put a K2 GSXR600 Rear Ductail on my 89 GSXR1100 and I reckon it looks awesome. Yet my best mate thought it looked rubbish. At the end of the day streetfighters are about us as individuals and what I like may not be what you like. So I'll throw up a few pics of 900RR's for you and hopefully it will inspire you for your build.I have a 99 900rr looking to change the subframe and tail section if you know which one would fit and flow the best please let me know I was thinking about a 06 r1 subframe and tail
The first post, first picture looks to be a 2004ish YZF-R1 tail with dual undertails.Thanks shadow zone I'm looking to steer away from the European tail look but what tail and subframe is on the 1st post 1st pick and 2nd post 2nd pic
