I bought My '99 1100S in 2003 with 14 k miles currently with 94 k miles.
I used to do 12k plus per year but have more bikes now so currently maybe 5 k per year on the S .
Replaced the following , Front wheel , ( the original is repairable ) 2x fuel pumps , ( preventive maint) 2 x front caliper rebuilds with pistons , currently have alternative calipers fitted, 2 sets of front brake discs fitted,
removed the abs in recent years ( more consistent brakes), 1 x right hand camshaft and followers ( wear noticed when investigating a noise) 2 x pushrods ( didn't cure the noise) , clutch slave cylinder ( preventive), rear bevel box at 93k (noisy/vibes) 2 x secondhand oe silencers (cracked/leaking)
Throttle cable set ( preventive).
1 x set of rubber inlet manifolds (cracked), 1x set of second hand throttle bodies ( noisy). 1x rear brake master cylinder (leaking).
3x batteries (never failed)
Routine oil&filters and pads , plugs , couple of alternator belts (never failed)
Swing arm bearings x 1 set , paralever bearings x 2 sets and one set of para lever pivots.
That's all I can think of at the moment...
1x non start at home , corroded fuel pump connector.
1x breakdown 2 km from home( very recent) , poorly crimped clip on fuel filter after fitting new pump to prevent breakdowns...
Don't do what i did and push home it damn near killed me
No valid comparisons really , Y2k CB 500, 80 k miles from new, 3 x clutch cables , 4x C&S sets( probably cost more than the bevel box..) , one front caliper rebuild. 1 x rear set of wheel bearings, one x neutral switch . Valve clearances never needed adjustment. 1x front and rear brake disc, usual service stuff.
