The only problem I see, is that their loyal customers are generally of the older age group ( apologies to those under 45 ) and are less likely to use a bike at their time of life. If it had been electrically powered, then perhaps the market size would have been bigger.
I am note sure if the large majority of the population even know what a Morgan looks like, let alone want to own one. Thats the problem that the MMC has too tackle, otherwise they will go the same way as Axminster carpets.
