Richard, first welcome to the GWOF. Second that is a fairly loaded questiion because in mechanical things there can always be issues, however there are many Wings out there with 200K+ miles on them so maintain it well & ride it for all it's worth.:happay:
Welcome to GWOF from Down Under. To get high mileage you only nrrd to do the basic maintaince.
Oil changes, filters, belts, cooling system, batteries, fork seals, stator, tyres.
It takes a lot of riding to do 3,000,000 miles.
