I look at it this way.1) If you have minor annoying problems that normally are covered under warranty will it cost more than £1250 to fix locally ? This seems unlikely.2) If you get a major serious warranty fault would it cost more than £1250 to freight the bike back to the original dealer? This also seems unlikely.With the amount of money you are saving warranty is not such an issue. Its more important to look at other factors - the history of the two bikes and also any differences between 2010 and new models (do the UK 2011 C5 have the kickstart for example). Also how does a new B5 compare price-wise with a second hand C5.
Would people be using them as primary transport for thousands of miles if they were all that bad?Do you take us for idiots? As we're using them? Go for it. Or buy a Honda.Or ask on a Honda forum!!
