Meguro 50cc : MA Amica (MAS Amica-Sport) It is MA:Amica which Meguro the medium size and whose large-sized motorbike were the main force planned as first mopeds class according to the trend of the world. With KH type (K Stamina) of 500cc class by which synchronous development was carried out at 7th Tokyo Motor Show by which started the trial production in June, 1960, it was made to complete in October, and way holding was carried out immediately, exhibition public presentation was carried out and popularity was won. From immediately after that, 100 mass-production trial production remainder is manufactured using the completed exclusive line. It was lent to the member's store of general agent organizations "Meguro-Kai" all over the country, the show and the exhibition were carried out in various places, and the trial production motorbike attracted the interest. However, in addition to performance aggravation of Meguro, it is said just then that interference with the small motorbike which was the prime product of Kawasaki was disliked, and it was made the selling stop by the business tie-up with Kawasaki Airplane Industry which negotiation was materializing at the same time just before marketing. Or two cycle cars which Kawasaki makes elated are opinions referred to as having presupposed that it does not build with Meguro, or there is also a report referred to as a production plan stopping having realized and having been stopped from the necessity of concentrating on other prime products by the so-called Meguro labor dispute which intensified from next year February, and it can be called the sale stop by having missed business opportunity anyway. By a prime medium size and a prime large-sized motorbike, it can be told by it having been impossible desiring a leap beyond this that it was aiming to gain a new customer layer to the background of having planned the small motorbike whose Meguro is 50cc. Honda has already announced Supercub and is beginning to occupy a share wonderful as a practical use motorbike of a moped those days. For this reason, it was the state that the maker who many practical use motorbike makers are dismissed, or is going to overcome by taking advantage by similar goods appeared. And Meguro was also influenced not a little. Although "Midget" which appeared on the other hand from Daihatsu Motor which was a three-flower automaker was lengthening the share by overwhelming budget prices and an overwhelming exploitation campaign, thereby, it is beginning to invade the share of a large-sized practical use motorbike. It is said that the business manager of "Midget" was actually appealing to the customer of Meguro. In such a situation, Meguro united the focus with the small motorbike (it is also a sport motorbike) by which the rate of occupying to the selling share of the motorcycle in Japan was extended greatly, and tried new entry. Meguro ages '58 and begins plan development of a 50 cc small motorbike. The motorbikes (except a scooter) of 50 cc class also including a sport motorbike were called the moped those days. Meguro aims at development of the characteristic moped which is not in a domestic moped being conscious of being late-coming. Mr. Reikichi Yura, the industrial designer who is the external specialist who had played the central role in 250cc : F type development, was appointed again, and he is requested from the whole composition (style design) development. It seems that according to Mr. Yura the request from Meguro is the sport specification which thought hobby nature as important, and considered the light and smart form to the concept. Mr. Yura proposes the motorbike style which will be in fashion based on the situation from an own Europe stay experience in Europe which was the advanced area of a moped from now on in consideration of on what kind of small motorbike popularity has taken off. The motorcycle model called Moto Gucci:Cardellino and NSU:Cavallino was mentioned as reference, it having been used as the lightweight sport specification in the appearance which emphasizes a straight line. Although the drives were the ambitious contents of a shaft drive as three steps of advance with 50cc single cylinder 4 cycle engine, or an automatic gear with a centrifugal clutch, the basic specification of a Meguro moped will develop 2 cycle engine newly for the first time as Meguro noting that there is a limit in small lightweight-ization with 4 cycle engine, when a trial production actually starts. Although MI type : single cylinder 2 cycle engine became specification with the characteristic of high rotation and a quantity horsepower of having taken it into consideration for sports models, having used the boa x stroke as 40x39 The automatic gear with three steps of advance or the centrifugal clutch which was the original plan specification, and a drive from consideration of the practicality which is also the company concept of Meguro a shaft drive It changed into the orthodox specification of the 4 steps of advance chain drive from the former, and was collected into the thick motorbike of torque which is easy to treat. An engine design is the young hope Masayasu Hayashi of Meguro group of technical experts. Development of each engine for models under new development is left to a wood with 20 years-old cost those days, and CA Cadet(125cc) etc. is dealing with it after that from 125cc : E3 of a first design. It is known for having dealt with the KH type two-cylinder OHV4 cycle engine for K Stamina(500cc) which becomes behind at the base of Kawasaki W series especially. About the design of appearance, Mr. Yura has acted as the supervisor also including engine as the point. The frame composition adheres to a straight line to the last, and in order to lightweight-ize as much as possible, the together joining point of a rear shock, and in order to allot even the tail end in a straight line further and to hang engine to this, the hammock form base of a reverse trapezoid is constituted from the handle head by the pipe like the backbone in the pipe. Engine prepared attachment Sutee in this base lower part, and was attached in it, a together joining point with the swing arm of Rear and the grandstand have been arranged at the same attachment Sutee, and the desirable form with which lightweight -izing and a design harmonized obviously is completed. Appearance has the square fuel tank near a rectangle by small size which blended the sport motorbike which the Japanese maker sold with the style by the maker of Europe to which it referred, and since the long single from which a sheet is also likely to turn into a tandem seat, the battery utilized and arranged in the hammock form base of a reverse trapezoid, and the tool box are hidden in the cover which felt it refreshed, it is visible also just like Battery less. Even if it applies to a muffler from an exhaust pipe, being conscious of a sport motorbike, it is rise type specification. Moreover, since the winker which was not duty, and the taillight are becoming commonplace by moped which the Japanese maker had already sold, it is equipped those days, a front winker is attached in handle both ends as a unit united with the handle switch, in order that between right and left may obtain 250mm, and appearance felt refreshed as the original plan is realized. In order to extend the range of a user, the "sport" (MAS) which is original sport specification (with a long single seat) is prepared for Amica with the "standard" (MA) which stopped the engine performance a little and made basic specification practical appearance (the saddle seat and the career were attached). Moreover, as for the "sport", two more kinds of specifications were set up by the difference in appearance (especially form of a Rear career), and convenience 3 type was planned. Although it considers that Amica which suited just before marketing excels by the design which is not so good to Honda CR110, the TOHATSU "RUNPET", etc. among whom the amateur race was also popular those days, the engine by which became a plan stop and precedence mass production was carried out with Amica of the 100-set remainder by which the mass -production trial production was carried out, without seeing sunlight is immediately said to have carried out abandonment demolition disposal. However, although it is a fact that thing touched the general eye at the show, and a non -returned car does not exist miraculously, either, if the situation which it is lent to affiliation each store of the distributor organization "MEGURO-KAI" of the Japan whole country, and is later called selling stop is seen, for the moment, it is supposed that thing is not existed. Although it imagines that a model like Amica may be accepted very well as seeing the prosperity of the sports model of a retro moped in fashion now, how is it? *** Principal statistics *** /(MAS) * Total length : 1,760 mm * Full-width : 650 mm (610 mm) * Total height : 1,000 mm (900 mm) * Distance between axis : 1,135 mm * Weight : 74 kgf * Engine type : MI type: Single cylinder 2 cycle * Entire aerodynamic volume displacement : 50 cc * Installed capacity : 4.2 HP / 7,500 rpm (4.5 HP / 8,500 rpm) * Full speed : 80 km/h (95 km/h) * Fuel economy : 90 km/L * Transmission : Advance 4 step rotary * Tire : (Front) 2.25~17-4 / (Rear) 2.25~17-4 * Starting system : Sel-motor
