my '01 1150 has done around 90,000 and I really dont think I have spent £1000 on it in the 60,000 I have had it.
I bought a job lot of 'H' rated Tourances from Germany for £100 pr have had to change 1 final drive bearing (£18),1 set of pads and a throttle cable set(£45).
Still on original front discs but put a 2nd hand 1100s one on the back that I had lying around.
Have changed 2 fuel filters 2 air filters and a few sets of plugs and also changed oil and filters at 6000 miles
3 x Mots at £20 (my mates shop, he also gave me a box of oil filters that he didn't think he would ever use) Twist and Go, Hatfield
Finally - I had to change 2 low beam light bulbs and one speedo bulb.
Sad thing is, is that it actually runs as good as the '05 1150GSA I bought last week. (and I prefer higher top gear)
