No experience, just a quick check of the Munn price
of $788 for the KTM stuff vs the Moto-Sport Baja cases & brackets for $885.
The Zegas are bigger but unlined, the Bajas... just the opposite.
Streamlined appearance doesn't mean much to me... I'd do the KTM bags and do my own liners, or the 37L H&Bs Andrew sells for $869.
