So I'm looking at my speedo reading today and it clocks over to 30,000 miles but on checking the registration papers I see that it went into service with the Ministry of Transport (Traffic Police) on the 9th March 1982 with zero miles, by 1987 it had done 38699 miles.
So that's 7700 odd miles per year on average for the cops, by 1989 it's done 60,226 miles which is 8600 miles per year.
It is then mothballed until 1996 and probably sold at Government auction, in 2005 it surfaces on the live vehicle register again but now the speedo reads 18797 so I'm guessing some plonker didn't like the original large speedo with the stop switch for setting when you chase other vehicles and has replaced this with a rather ordinary Honda speedo.
On the 20th October 2008 I buy it and it has now got 27641 miles on it.
Given that at some time it sat for 7 to 10 years off the road and I can only account accurately for 69000 miles of this bikes life, just how long do they keep going with the original engine in them? I know from the engine/frame numbers that she is all she was when she came off the production line in Japan so at somewhere in the region of 70,000 miles how much more can I expect from this one engine?
