I'll claim my smart butt points for that one then
WRT 6 hours labour -tell them to fook right off
Wheel bearings - 45 mins total inc removal and refitting wheel
Strip front end to get at headstock - 40 mins inc removal of bodywork
Fit bearings - 1 hour
Reassemble - 1 hour inc cleaning the bike
To my mind thats 3.5 hours and I'm no Honda mechanic with a proper workshop and all the right tools!!
