I am looking to get an Across and i have gone to have a look at a few bikes. I am unsure about a few things: - All bikes that i've looked at have not had a complete service history, or receipts / stamps of services. Is this considered normal? Should I expect the seller to have service logs conducted from 0km? - Is it risky to buy if the seller does not have a warrant/service manual and /or receipts for services done. - In particular, I had a look at a '98 Across with 15000km however they had no record of service although they insisted it had been serviced by a friend. For this bike i'm looking to pay approximately 3400, and have to replace tyres and do a full service, bringing the price to approx. 3800. Does this sound reasonable? Ive done most of the main checks already listed on the website, my main concern is that the service history is never complete.
