rode 06 last year for bout 6000 miles bike is very good you could get them for 3999 . 2007 s2 is the same as 06 model bar new swing arm comfy seat clocks fairing different engine the same. the uk is not getting the lower bhp option same as last yr 98bhp. and almost forgot new brakes on the s2 model.. a much improved model on an already good bike.
be careful with regards to the 06 model as lots of dealers still had 2005 models kicking around usually have silver engines and silver frames apart from abs model and a few black ones , 06 colours were lava red yamaha blue and towards the end of year black as yamaha ran out of faired models.. have seen a few dealers selling pre reg 2005 spec r6s for as little as £5000... happy hunting stueee
