Early 1200rts
Have a 2005 model with 50,000 miles on it.
My only regret about it is that I did not buy one with cruise control.
Makes journeys less fraught if there are speed limits.
On to the bike and what has or has not been done to it:
I change the oil and oil filter every October.
That's it, other than tyres and rear brake pads (Goldfren -Ebay - Dirt cheap - excellent)
Before anyone asks: No, I have never checked, never mind changed the oil in either the rear hub or gearbox, nor changed the bloody brake fluid.
I have never washed the bike either.
What has gone wrong:
Started missing at circa 20,000. New plugs cured it.
Fuel pump controller at circa 22,000.
At circa 45,000 a crack appeared in left hand footrest. Bought a second hand one off
Motorworks.
Gear position indicator has occasional hiccups at present, but too much effort to replace it.
Good, troublefree bike.
Round Europe every year.
I never check oil level from one year's end to the next. It does not use oil.
The occasional one has servo problems, but only a small percentage.
Like the rear hubs, if you have a good one, you have a good one.
If you have a bad one, no amount of oil changing or brake fluid changing is going to fix it or extend it's life.
