hi, tbh 40,000kms the bearings will be knackered anyway, so greasing them then is a too late!

better to get it done as soon as you get the bike as there's not much grease in to begin with.

as for is it on a service schedule i have no idea, i'm guessing it will be like changing the brake fluid, you will most likely have to prompt the dealer into making it into part of the service/maintenance
