Look at it this way, a mate of ours has a GSXR (updated every 2 years or so), I have an M1000sie.
I do about 6 - 10 thousand miles per year, he does about 15 - 18 or so.
My service intervals are the same as yours - his are same time schedule as ours, OR 4 thou miles (whichever is sooner)- as recommended by Suzuki, to keep warranty valid.
He has at least 4 services a year costing about £350 - 400
I have one or 2 costing £250 - £400 (depending on major/minor, and yes - I know mine is cheaper than yours, as it is aircooled & doesnt have fairings)
He therefore spends more in servicing each year than I do.
I dont know of any manufacturer selling in the UK that doesnt lay down rules for service intervals - but I am happy to be corrected (unless by Dibble:P )
Sorry to echo the lads above, but it is something you should look into when buying ANY new bike/car etc & compare costs for mileage/use.
