Special framed bikes - Krauser, Rickman,Dresda Honda and Simoto ?

A friend,Dave, who I first met approx 19 - 20 years ago is particularly a fan of  BMW boxers, but also likes bikes that have 'special' frames. He got in touch with me last Summer when a old bike of mine - Sidlow framed BMW - was up for sale on Ebay. Coincidentally another friend had put the seller in touch with me. To cut a long story short the seller let me know that he'd let the BMW go for a lot less than the original listing. It now became of interest to Dave and after a phone call they agreed a price etc only for the seller to renege on the deal. Obviously in the day or so that passed he'd had a more financially rewarding offer. Dave was particularly disappointed / gutted as he'd agreed to sell his modified Z750 at a very reasonable price just to help finance the purchase.
   Anyway,what came out of this was a few pics of  his other 'Specials'. He actually no longer has the Rickman, deeming it too uncomfortable.
