I have owned this from new, now 9 years old. Apart from consumables, only header pipes have been changed to stainless steel. Makes 93bhp on dyno, and does 12 second quarters at santa Pod, so not much slower than newer ones. Have done trackdays, mostly ridden hard on sunny days, no breakdown in 9 years. Still on original battery, clutch, brake lines and shocks. Strengths: Cheap running cost, even the insurance is £75 a year. superb reliability, build quality is excellent. Weaknesses: Lots about, but being this good its to be expected.
