As previously suggested, buy from a dealer and you are covered for two years, I’ve had the 2013, 2014. 2015, 2016, and get my 2018 next week. They have all been fabulous bikes, each one getting better than the rest, although my 2013 bike was the most exciting, the 2014 is the better of the two bikes to go for with the heavier crankshaft and the fitted steering damper, the motor felt more grown up and the fuelling was better at town traffic speeds on the 2014 bike, also the damper did calm the steering down at bit on fast bumpy corners.
No issues at all with any of my bikes, approx 8,000/11,000 miles per annum.
Go out and buy one you’ll love it!
