After the shaft drive on my R1150R broke at 50k miles (a common fault I'm lead to believe) I'm thinking of selling the piece of German junk. Apart from the shit build quality and crap indicator switches that need 3 sepearte buttons to operate them the thing that irks me the most is the fact that I have to fill the tank every 160 miles, a real pain as it needs a fuel stop every day if I'm commuting to work or every few hours if I'm on a long run. being able to get 200 + from a tank full would be an advantage.

Anyone got a XJR1200/1300 tell me how many miles it'll do to a tank?

And any other problems the bike suffers?

About 150 miles then onto reserve. (And I've never pushed my luck to see how far that goes.)

Apart from a tendency to overtake everything in sight, no.

If it's abused, it'll go through rear tyres, chains and clutches, but then so will anything. Most of my mileage is two up, with luggage. Rear tyres (BT020s) do 6k, just changed chain and sprockets at 22k (front sprocket slightly hooked) and the clutch is sound. I've got a temperature gauge that screws in place of the oil filler cap, useful on slow runs like the Wootton Bassett ride.
