Saw this on the Bonneville owners facebook page: Neat looking side bag until you find out that it costs 225.00 Euros! Alternatively, saw this on a Bonnie at the DGR this year and thought it didn't look too bad but assumed it would be treble figures. Turns out to be a mans shoulder bag for about £18.00 on Amazon! https://www.amazon.co.uk/Kaukko-Sho...TF8&qid=1508414238&sr=8-5&keywords=kaukko+bag
I've seen loads of different bags on Bonnevilles in different sizes either canvas or leather. I've seen people making great use of old canvas ammo pouches and respirator bags as well as dispatch and messenger bags. I saw one a few weeks ago with and old canvas tool roll attached, a neat way of carrying a set of spanners. Fleabay is a great source especially for leather.
I have a leather ammo pouch either side of the Bonnie for disc lock and tool kit. Austrian StG58 - bought as a pair for £6.99 on ebay.
Not planning on getting one myself! It did look better in the flesh than the picture to be honest and I was surprised how cheap it was at it did look good quality.
