Good point about the Motobatt. I had one in my other bike (Honda CX500 Turbo) and it failed without warning after about 18 months. I do put that bike on a battery tender about once a month.I've had two new Motobatts fail me in the last year and have now changed brands. I have been using them in all of my eight bikes until now and rated them highly on both price and performance but I now believe (rightly or wrongly) that they don't like trickle chargers. This non-scientific knee jerk response is probably unwarranted but I decided to buy a $25 Powerline from ebay and so far it works very well indeed. If it turns out that the problem lies with my Ctek charger then I'll know soon enough. However, if money is no object, then I'd always recommend Yuasa for longevity.
