Lubricating TRF201 Bearings?

[Origineelreclamebord]

Just a quick question... Do the bearings supplied in the TRF201 need re-lubricating or not, and if so, with what oil is it adviced to relubricate them?

The thing is, So far the bearings I've bought were always for bashing and filled with grease and I didn't really ever give them attention because they didn't seem to need any. With my TRF201 being faster and doing stuff tougher on the bearings than I ever did before, I think it would be a good idea to inform myself of the maintainance needed
