Changing rear wheel bearings and crank shaft for a gilera DNA 50 cc?

how much will it cost to have the rear wheel bearings for a Gilera DNA 50 cc (2004) model changed?

Also how much for the crank shaft to be changed?

well its alot of work mate the crankshaft requires the entire engine to be removed and split in half to be removed and the output shaft bearings are a mixture of ball brearings and needle rollers they need to be removed using a blind bearing removal tool and its accesabel by removing the plate behind the clutch in the trnsmission.if i was doing the job i would charge 180.00 labour and the cost of the bearings too.the main bearing are special and need ordering from the bike trade a bearing supplier will not be able to get them as they are only released through the bike trade.bring it to me and ill do it :) i like working on Them.i got 3 dna's
