I want to reslove some questions aboutt the bearing on the wheel axle
on the classsic Vespa scooters.
Piaggio Partnumer 090025 is a 6204 C4 (or sometimes C3) bearing.
nowdays it is replaced with Piaggio partnumber 434735.
The substitute bearing No 434735 has builtin seals, works fine for the
scootamatic Vespas, but are they reaally asubstuitute for the VGLA, VBB and others?
The question is, has the bearing 434735 also C3-C4 classification ?
