I am currently running in the bike work permitting and tend to agree that the 4000 rpm limit is sometimes unavoidable to keep to. I have adopted a TRY to keep it to 4000 rpm but if it goes over then so what. If an overtake needs more rev`s then I will use them but not hold them afterwards.
I do agree that every mechanical device does need a period of bedding in but likening a jet engine to a motor cycle is beyond me. The motorcycle is a mixture of differently functioning parts each needing to bed in in different way. I would treat the motorcycle with a certain degree of symphathy until the first oil change but then its game on.
By that time the tyres, brakes, chassis, suspension and engine should be bedded in and checked by the dealer. Any immediate initial manufacturing faults would have become apparant and would be dealt with. Thats what I think that the running in period is. A test to see if they have got it right. If the machine survives this period it is proberly ( looked after properly ) going to last its service life, whatever that is.
I would suggest to people running their bikes in, is to use this initial period to get to know it, enjoy it, and dont get hung up about over revving it for brief periods. Check it often, ride it lots, get it out of the way as quickly as possible.
