Alloy Wheels and Access to Bearings Question

[DoubleT]

Looking at the newer model TM that now come with Alloy Wheels how do you access the grease fitting to service the bearings. The alloy wheels have a chrome hub cover that covers the hub. Is there a removable center part of the hub cover that comes off to provide access? Or do you have to remove the entire wheel to access and service the bearings???
