| | |
| Presented at the Bologna Motor Show in December
| |
| 1984 and sold shortly after the Cagiva 125 GP S1 incorporates a historic
| |
| designation: Aletta was a famous 125 built in the sixties by then Cagiva
| |
| Harley-Davidson and Gold Wing was the fastest single-cylinder Varese intended
| |
| for private pilots. The Golden Fin thus provides a motorcycle style and advanced
| |
| features that clearly show the will superstructure 'of the house from Varese to
| |
| propose measures to be 125 with a medium capacity. Where the various AS-R NS-F
| |
| and RV have difficulties 'to hide their appearance from motion-read, the S1 has
| |
| little presence and size, indicative of the effective displacement and, in fact,
| |
| more' than anything else found one eye carefully written and 125! Unfortunate
| |
| that despite the big line, although the valid cycle, reveals the true
| |
| displacement vane Gold for driving experience more 'mature and average engine,
| |
| we must' wait Gilera KZ 1986. Technically, the S1 is also equipped with less
| |
| competition, can not boast either the exhaust valve or an electric starter.
| |
| The S1 and S2 were not his descendant of the great commercial success, although
| |
| for those Cagiva piu'avanti would arrive shortly with the next arrow and Myth.
| |
| Price in 1985: 3,979,100 Lira
| |
| Colors: Red / Grey Metallic.
| |
| | |
| The bike soon
| |
| The generous sizing of all components, fully stretched out toward the front
| |
| lines, the rounded and excellent proportions, give the S1 a remarkable sense of
| |
| unity and momentum of solidita'tipica cilidrata greater. The housing and the
| |
| overall level of finishes are consistent with the high price.
| |
| | |
| The sides, pressure mounted, concealed in the battery right and left air filter.
| |
| On the right side of the hull is a door giving access to the cap for the
| |
| radiator and water pump, rear brake, curiously located in posiozione elevated on
| |
| the right side. The seat protected by a removable lock located on the tail,
| |
| hiding the front tank for mixing oil and a cosmetic bag for tools, while in the
| |
| back just below the tail, is a handy compartment space-objects.
| |
| | |
| The instrumentation Sleep Borletti, although it looks very orderly, and
| |
| 'complete and easily readable even at night. The equipment is' very complete and
| |
| in addition to contakm (also graduated in mph), tachometer, termomentro water
| |
| and a large battery of lights, also boasts the first fruits of a digital gear
| |
| indicator light and a fuel level. The electric controls are the classic and well
| |
| made CEV period and commonly used in other bikes.
| |
| Ciclisitca
| |
| | |
| The frame follows technical trends typical of the mid '80s and therefore, here
| |
| is the structure of double-cradle tubular steel panels abbianata a classic steel
| |
| swingarm. The front there is a telescopic hydraulic fork with 35mm Marzocchi
| |
| antidive device adjustable to three positions, while rear there is always a
| |
| shock absorber adjustable in spring preload and Marzocchi called by Cagiva "Soft
| |
| Damp". The braking system and 'a very valuable Brembo Gold Series, with the
| |
| front of a pair of 220mm floating discs served by fixed-piston caliper and the
| |
| rear a 220mm floating disc ever and ever served by dual-piston fixed caliper .
| |
| The alloy wheels have smaller three-spoke 'contained and betray the true
| |
| displacement of S1: 90/100x16 to' front and 100/90x18 rear.
| |
| | |
| Engine
| |
| | |
| Derivation of motocross, the engine of Cagiva Aletta Oro, although powerful,
| |
| does not give much technical solutions of the moment. Provided admission
| |
| laminated into the cylinder, with up to 10 lights, automatic mixer and cooled
| |
| forced circulation, the engine of the S1 'rather devoid of anti-vibration
| |
| countershaft, electric goodwill (even demand) and, more' serious exhaust valve.
| |
| As known, the exhaust valve not only serves a marketing function, but rather
| |
| 'has the important task of changing the timing of the discharge depending on the
| |
| number of laps, and then allowing the adoption of suitable distribution diagrams
| |
| to seek maximum performance at high speeds without compromising the shot low and
| |
| medium rpm. From this point of view, the S1 sins clearly, since the adoption of
| |
| a cylinder particularly encouraged to stay competitive with the competition has
| |
| negatively affected the delivery at low and medium rpm, where holes are evident
| |
| annoying delivery. 7000giri exceeded, the engine runs very well and pulls strong
| |
| until almost 9000giri, but the rev range and is diminished to the detriment of
| |
| the quality 'of driving.
| |
| | |
| With regard to performance, S1, despite the problems mentioned above, does not
| |
| behave quite badly and with a maximum power to the wheel to 21.01cv 8750giri is
| |
| the most 'powerful of its direct competitors AS-R NS-F and RV, and second only
| |
| to the AS-R in terms of speed 'principle with 139.700 km / h (140.300 mph for
| |
| the AS-R). On the other hand, evidence of recovery in the 400 meters to 50km / h
| |
| show very well the lack of tractability 'of the engine, the S1 recorded the
| |
| worst result of the class a time of 23.035 sec and a velocity' output of only
| |
| 76.590 km / h (19.157 seconds and 104.046 km / h, the leader AS-R)
