Having bought the ultimate addons pro motorcycle bike mount kit (see separate review) which arrived just a few days after my order, I went to fit the kit to my sports bike but found that I didn't have the conventional tube style handlebar but a flat central yoke. This is the answer - very neat solution and really well made but 2 words of caution to any buyer - 1) check very carefully the internal diameter of your head tube as there are 3 different size adapters available. 2) if you have already bought your UA smart phone or satnav case check what kind of mount it has on it - if like mine ( I phone 4) it has a female 3 pin plate you will also need the 1 inch 25 mm ball to 3 pin adaptor sold separately - not clear from website you will need this. However very good service from ultimate mobiles lady who kindly sent by express delivery. Recommend.
