I think you'll find the UK distributor are Motohaus in Hampshire and calamander are just a stockist unless they have become the importer in the last month or so.
www.motohaus.com JohnW if you've fitted a single seat subframe you will need the single seat kit, but the fittings vary for alloy or steel subframes. i.e. different part number for 998S mono steel subframe D013/B and998S mono alloy subframe D006/B
I have the Ventura catalogue if you need to check or contact Ventura direct in New Zealand (search on Google, they are very helpful)
If you have a single seat on a Bip subframe i'd check with ventura themselves to be sure.
