Yes, BMW do not have shops as such, but this site which has been referred to on this thread is United Online Stores GmbH (see extract from website below), of which
www.BMW-Motorrad-Bohling.com sells genuine motorcycle clothes and equipment by BMW Motorrad. More importantly, if a UK franchised dealer not only openly recognises them but will also genuinely honour the 2 yr BMW warranty, then it's all legitimate then, isn't it? I think so, and I also realised (some time ago) the huge mark-up BMW put on thir goods sold here in the UK, irrespective of the onerous 20% VAT.

Welcome to
United Online Stores! We are a young company based in the city of Karlsruhe operating several multilingual
online stores selling
motorcycle and
bicycle equipment and clothes. We are not only active in Germany but also in Great Britain, Italy, Spain, and France.
We made our first tentative steps on the online market by selling
used motorcycle parts on a popular internet auction platform. The once small ebay department of a motorcycle retailer has grown into a separate autonomous company,
United Online Stores GmbH".
