I bought this from highside motorcycles (
http://www.highsidemotorcycles.co.uk/) for a very reasonable £35 plus £4.95 p&p, delivery was quick and communication was good.
It seems very well made and fits the wee tank nice and snug. The magnets are very strong. It isn't a large capacity but you can squeeze a pair of waterproofs in the main pocket. There is a seperate pocket for your phone and another seprate pocket to put your mp3 player with a hole to put your earphones through if you like listening to music on the move, it is big enough to fit your wallet and other stuff in here. It is only shower proof so there is a rain cover in another pocket. It also comes with a shoulder strap.
I bought it mainly for popping the camera in and for easy access to travel documents. I will be using a protective mat under the bag to stop any scratches as the magnets make a right 'clunk' when you fit it.
