the only problem i had was when,after five years the engine pack in on me. recommend change bike after three years. service every six months, even that i only do 2500 miles a year, and just died on me, just put a new exhaust on and a service. but still love the model and getting a new one, this week. just bad luck,spending £400 and six months ago spending £900 on sorting out the engine,was exspect it to last a couple more years. but being self-empolyed and putting it down against tax, the bike cost me about £15 pound aweek. but if i had change it after three years, i would have got aleast £1500 for it, and that would of cost me after putting it against tax, would of work out £6 aweek, as of now costing me £15 aweek and left me with a pile of metal. so recommend to sell bike after three years and buy a new one it save you money in the long run..... peter
