Norton Manx.
If you’ve never heard of the Norton Manx, you haven’t been paying attention. No other motorcycle has turned as many laps at the Isle of Man TT. 
Brough HB.
This Brough was one of three models offered in 1915. It featured a 497 cc horizontally opposed twin mated to a three-speed Sturmey-Archer gearbox. 
Brough-Superior MK1 replica.
This is a faithful replica of a 1921 Brough-Superior MK1 with an authentic J.A.P. side-valve V-twin. Only three MK1 models would have been produced in 1921. 
Hildebrand & Wolfmüller replica.
This Hildebrand & Wolfmüller is the first ever production motorcycle. Well, not this one — it’s a replica. The first one was made in 1894 and was powered by a 1,488 cc water-cooled, four-stroke twin. Quite innovative for a first kick at the can. 
Münch Mammut.
The first time I heard of a Münch was sometime in the late 1970s in a motorcycle magazine, and it was weird even then. Friedel Münch founded the company in 1966 by sticking a 1.0-litre air-cooled NSU car engine into a chassis of his own design. The aptly named Mammut (Mammoth in English) seen here is a later model featuring a 1.2-litre NSU inline four, that produced a not-so-astounding 87 horsepower. Münch made 476 motorcycles before closing shop in 1975. 
Whizzer Tandem.
Whizzer was known for making bicycle-mounted engines throughout the 1940s, but also produced a few motorcycles, like this rare 1946 Whizzer Tandem. 
Neracar Type A.
Neracar motorcycles were produced from 1921 to 1927, initially in Syracuse, NY, and later in Kingston-on-Thames, UK, as Ner-A-Car. This is a very early Neracar Type A. It featured hub-centre steering and a 221 cc two-stroke single. Transmission was CVT. About 50 are known to be in existence today. 
Hercules W-2000.
In the 1970s a few motorcycle makers dabbled with rotary engines, including Germany’s Hercules. The W-2000 (W for Wankel) was produced from 1973 to 1979. Its single-rotor engine displaced 249 cc and made 27 horsepower, or about as much as its piston-powered equivalent, but while burning much more fuel. Rotary engines never caught on. And we’ve got even more. Click Page 3.
I have been by there several times and have stopped for a coffee at the cafe even, maybe I’ll have to take some time and check it out next time. Timmelsjoch is a great road also.
How did you manage to pare it down to these gems. Looks to me like there should be a follow up article. Is that an Imola Ducati in the first picture or a replica
