Wheel bearings, in fact wheels in general tend to be overlooked with mechanical reliability taken for granted - and of course for most of the time this is not a problem.
During the winter period when the machine is less likely to be used on a regular basis, why not take out the wheels and check for wear and/or damage, not just tyres, but bearings, sprocket & chain, sprocket carrier and a number of other components that make up, arguably, the most fundamental assemblies on a motorcycle?
Other wheel related components you may wish to consider:
Add as many parts as you wish to the same shopping cart, new fastening screws, nuts & bolts 74810461A 77913991A for example (look nicer than reusing the old items), and still only pay the same single fixed price shipping cost. This component may have other applications within the Ducati model range. Please ensure the part numbers are correct for your machine prior to placing your order.
