Assembled by Dutch entrepreneur Michael Buttinger, the collection comprises almost 100 machines, the majority of which are Hondas ranging from the humble but design-classic 50cc Super Cub to the technological tour-de-force NR750. The NR75O is estimated at a value of £50,000-70,000. It was designed with no expense spared by Mitsuyoshi Kohama, and intended to showcase Honda’s advanced technology.
Also on offer are a selection of early Suzukis, Kawasakis and Yamahas, a variety of later 1970s and 1980s classics, and two prototype engines—a sand cast CBX1000 and a CX500. Many of the motorcycles are effectively new or unused, and many have only a handful of ‘push’ miles recorded.
Outside The Buttinger Collection, the 1974 Kawasaki 500cc H1-RW 500cc triple is estimated to sell for a value between £60,000 and £70,000. Japanese works Grand Prix motorcycles from the 1970s are exceptionally rare and even rarer in private hands, most having been either scrapped or consigned to museums. So the Kawasaki is sure to attract attention from collectors. It is one of only two machines built by the factory for the French Kawasaki importer SIDEMM for use in the 500cc World Championship. The bikes were ridden during the 1974 season by the French endurance racing specialist Christian Léon and French-Canadian Formula 750 star Yvon Duhamel.


Other desirable British classics include a 1938 Vincent-HRD 500cc Meteor ‘barn find’, acquired by its recently deceased owner in the late 1940s and laid up since 1957, estimated to fetch bewteen £22,000 and £26,000, and an incomplete 1939 Brough Superior 980cc SS80 restoration project, estimated at £10,000-15,000.
