10 years, battery and rear box
My 2002 147's battery gave up the ghost this week, but that was the original factory battery so it's lasted 9 and a half years which is pretty impressive. I was really surprised it had survived the last two winters. The breakdown guy who rescued my wife was gobsmacked.
I changed the rear exhaust today for a timax one, which looks ten times better. I'd put off this job for months but couldn't wait any longer. The box was a ******** to get off but got there in the end. Once i got the clamp off it slipped off not too bad. Again this was the original part and was still serviceable after all these years - just looked pig ugly and I'm glad to see the back of it.
