For those that want more luggage capacity. My California with the Baglux Bagster black/white tank cover and bag.
For those not familiar with Baglux, the tank covers are available for most bikes and there are varying sizes of bags available.
The covers for the California are also available in white and plain black although I must add, the eagle badge was hand stitched on, by my good self.
I can’t recall the storage capacity of my bag but it does come with detachable shoulder straps so can be used as a backpack when off the bike.
As nice as the OEM tank bag is, I already had the bag from my previous bike so it made sense to buy the California tank cover. Having used Baglux on various bikes for many years I would certainly recommend this system, certainly in terms of price and quality.
