I thought I'd share this in case it's of interest. I already have one from this company for another bike and it's been great, I'd been putting off and forgetting I wanted one for the Bonneville. This is their cheapest option for an indoor dust cover and, despite this, it's fantastic quality and will even offer protection against minor bumps. The lining is very fine breathable fleece with a degree of cushion to it. I asked for it to be customized to allow for bar end mirrors suggesting they use the same pattern as per the Thruxton, and asked them to accommodate the rack for which provided some measurements and a photograph. I have to say they've excelled themselves and I couldn't be happier. Not particularly cheap at £99 but worth it. Machine washable in a regular sized washing machine too. Excuse the busy/messy backdrop!
