== Review ==
On the other hand, a glorious brand like Gilera, today almost abandoned kept alive for a kind of therapeutic hardship, in the past and especially between the eighties and nineties was a thriving producer of 125, sports and enduro, which made a whole generation dream. The forerunner of the 1980s road enduros was undoubtedly the RX 125. At the same time as the RV125 road, the Casa di Arcore presented its enduro cousin, named RX125, at the 1983 Milan Motor Show. In common, the two bikes had the engine, slightly revised in the RX, which therefore had one horse less, a practice widespread at the time by all the motorcycle manufacturers, who used the same thermal group for road and enduro models, usually intervening on the power or on the beams.


Gilera RTX 125
The bike had the classic road enduro line of the time, so with mask and high fenders. The frame was a closed double cradle tubular with boxed plate reinforcements, floor that he always shared with the RV.


The engine was, of course, the 124.3cc two-stroke single-cylinder, with a 56 and 50.5 mm run and a run, respectively, with a laminated and counter-shaft, powered by a 26 mm Dell'Orto PHBH carburetor, which is identical to that of the RV. The different exhaust system and some slight changes to the thermal group resulted in a slightly different delivery and a maximum power of 19 hp at 7,750 rpm, compared to the 20 hp at 8,000 rpm of the RV.


The gearbox was 6-speed and pedal-starting, but with 150,000 lire more it was possible to have the electric one. The bike had a 35 mm Marzocchi fork with 200 m of excursion, while the rear fork adopted a shock with 185 mm of excursion. The wheels had professional enduro sizes, with the 1.65x21 front with 2.75 tire and the 2.15x18 rear with 4.10 tire. The brakes were mixed, with a 230mm front disc and a 140mm rear drum.


The tank eventually had a capacity of 13 liters. The instrumentation was quite complete, as in the two circular instruments it provided speedometer, counters, gasoline indicator and temperature plus four spies for crazy arrows, oil and dazzling. The RX 125 reached a stated top speed of 115 km/h, in line with the competition.


Speaking of competition, in fact, at the time it was not
there were still many rivals of this bike. In practice, the only one to give
thread to twist to the enduro of Arcore was the Cagiva Aletta Red, which paid
however, a slightly lower power of the project is slightly lower (little
more than 15 hp), although it had from its an even cheaper price of
2,550,000 land and in those years sold about 1000 units per month.


Once again, as with VR, Paolo Martin took care of the design. During the
realization of the project was also thought of a Dakariana version with
increased tank, which at the time was quite a lot even among 16-year-olds.
Immediately after the presentation of the RX, then came the Arizona RX, which
22-litre tank, with an eagle on a star-like background
and stripes in homage to the state of Arizona, but also for some accessories
Africans such as the bellows to the fork, the disco cover, the parasassi grill
on the front headlight, the handrails and the back tool bag.


The colors available at launch were for both the RX and
for the Arizona RX the white with red friezes and black saddle (later on the
Arizona the saddle turned red) or red with black saddle and later
black with red saddle. As with the RV, the RX was also presented with the
200 version with 183.4cc engine, achieved by increasing the laose to 68 mm.


From the always valid site gilerarv200.it we find that, at
in March 1984 the House of Arcore immaculately registered 385 RX,
roughly half of the Red Wing, which were 725 in that month but 3,675
from the beginning of the year, since it entered the market before. At the end of
that year, the Gilera RX and RX Arizona reached 6,475, more or less always
the half of Cagiva, which touched 13,652, but Arcore's house surpassed that
total registration numbers. The challenge was open!


In 1986, or rather at the end of 1985, there was an evolution
rather important of the enduro brianzole. In fact, they were presented, in
replacement of the RX and Arizona, the RTX 125 and the Arizona Hawk RX, both
with more powerful engine and 70% redesigned components. The two bikes
even though the public's preferences tended more towards
lArizona Hawk, who had a stronger story and above all an appearance and a
evocative names of great rallies.


These at least seem to be the least rational and
more emotional than they did prefer the RX to the RTX. In the meantime, at the Rally of
Sardinia in 1985, the House of Arcore presented itself with a motorcycle called the RX 250
Arizona Rally, which was really nothing but the prototype of the future RC
Rally 250, sister of 125.


Returning to the Road RX and RTX, both models were
black or white livery, coupled with the red saddle. In practice, new
were all the plastics, just as the instrumentation was redesigned and it was
added a paramotor plate.


Also renewed is the chassis, the Paioli fork, the 240 mm disc brake, the
gold anodized circles (optional) and much more. While the tank
of the RTX remained 13 litres like that of the RX, that of the Arizona Hawk
became a little smaller than the Arizona tank: it went down in fact
22 to 17 litres.


On a mechanical level, the Power Jet system is not
BPF (By Pass Feed) which extended the feeding
compression phase, as well as a new electronic ignition control unit
Capacitor Discharge Ignition (CDI) and a different CDI (Capacitor Discharge Ignition)
Exhaust. The declared power increased to 22 hp, delivered to 8,800 laps (25 hp to 7,500
200), while the top speed was 125 km/h.


It also went up the price, taking it to over 3,500,000 lire,
while the electric starter increased its price by 100,000 lire in just two
Years. The RX paved the way for the subsequent enduro of Casa Gilera, which from there
little gradually increased the list of models on the list.

Motoblog.it review
 
 
D’altronde un marchio glorioso come Gilera, oggi pressoché
abbandonato tenuto in vita per una sorta di accanimento terapeutico, in passato
e soprattutto tra gli anni Ottanta e Novanta è stato un florido produttore di
125, sportive e da enduro, che hanno fatto sognare una generazione intera. La
capostipite delle enduro stradali anni Ottanta fu senza dubbio la RX 125.
Contestualmente alla stradale RV125, la Casa di Arcore presentò al Salone di
Milano del 1983 la sua “cugina da enduro”, denominata appunto RX125. In comune
le due moto avevano il propulsore, leggermente rivisto nell’erogazione sulla RX,
che aveva quindi un cavallo in meno, una pratica molto diffusa all’epoca un po’
da tutte le case motociclistiche, che utilizzavano lo stesso gruppo termico per
i modelli stradali ed enduro, intervenendo solitamente sull’alimentazione o sui
travasi.
 
La moto aveva la classica linea da enduro stradale dell’epoca, quindi con
mascherina e parafanghi alti. Il telaio era un tubolare a doppia culla chiusa
con rinforzi in lamiera scatolata, “pianale” che condivideva sempre con la RV.
 
 
Il motore era ovviamente il monocilindrico due tempi di 124,3
cc, con alesaggio e corsa rispettivamente di 56 e 50,5 mm, dotato di ammissione
lamellare e contralbero, alimentato da un carburatore Dell'Orto PHBH da 26 mm,
quindi identico a quello dell’RV. L’impianto di scarico differente e alcune
lievi modifiche al gruppo termico determinarono un’erogazione leggermente
differente e una potenza massima di 19 CV a 7.750 giri, rispetto ai 20 CV a
8.000 giri della RV.
 
Il cambio era a 6 rapporti e l’avviamento a pedale, ma con
150.000 lire in più era possibile avere quello elettrico. La ciclistica contava
su una forcella Marzocchi da 35 mm Ø con 200 m di escursione, il forcellone
posteriore adottava invece un ammortizzatore con 185 mm di escursione.
Le ruote avevano misure da enduro professionale, con l’anteriore da 1.65x21” con
pneumatico 2.75 e il posteriore da 2.15x18” con pneumatico 4.10. I freni erano
misti, con un disco anteriore da 230 mm e un tamburo posteriore da 140 mm.
 
 
 
Il serbatoio infine aveva una capienza di 13 litri. La
strumentazione era piuttosto completa, visto che nei due strumenti circolari
forniva tachimetro, contagiri, indicatore benzina e temperatura più quattro spie
per folle frecce, olio e abbaglianti. La RX 125 raggiungeva una velocità massima
dichiarata di 115 km/h, in linea con la concorrenza.
 
A proposito di concorrenza, a dire il vero all’epoca non
esistevano ancora molte rivali di questa moto. In pratica l’unica a dare del
filo da torcere alla enduro di Arcore era la Cagiva Aletta Rossa, che pagava
però una maggiore anzianità del progetto una potenza leggermente inferiore (poco
più di 15 CV), anche se aveva dalla sua un prezzo ancora più vantaggioso di
2.550.000 lire e in quegli anni vendeva circa 1000 unità al mese.
 
Ancora un volta, come per la RV, del design si occupò Paolo Martin. Durante la
realizzazione del progetto si pensò anche a una versione “dakariana” con
serbatoio maggiorato, che all’epoca andava parecchio anche tra i sedicenni.
Subito dopo la presentazione della RX quindi arrivò la RX Arizona, che si
differenziava per il serbatoio da ben 22 litri, con un'aquila su sfondo a stelle
e strisce in omaggio allo stato dell’Arizona, ma anche per alcuni accessori
“africani” come i soffietti alla forcella, il copridisco, la griglia parasassi
sul faro anteriore, i paramani e la borsa porta attrezzi posteriore.
 
Le colorazioni disponibili al lancio erano sia per la RX che
per la RX Arizona il bianco con fregi rossi e sella nera (successivamente sulla
Arizona la sella divenne rossa) oppure rosso con sella nera e successivamente
nera con sella rossa. Come per la RV, anche della RX venne presentata la
versione 200 con motore da 183,4 cc, ottenuto aumentando l’alesaggio a 68 mm.
 
Dal sempre valido sito gilerarv200.it scopriamo che, a
livello di numeri, nel mese di marzo 1984 la Casa di Arcore immatricolò 385 RX,
più o meno la metà delle Aletta Rossa, che erano 725 in quel mese ma 3.675
dall’inizio dell’anno, visto che entrò in commercio prima. Alla fine di
quell’anno le Gilera RX e RX Arizona raggiunsero quota 6.475, più o meno sempre
la metà di Cagiva, che toccò quota 13.652, ma la casa di Arcore sorpassò quella
varesina come numeri totali di immatricolato. La sfida era aperta!
 
Nel 1986, o meglio alla fine del 1985, ci fu un’evoluzione
piuttosto importante delle enduro brianzole. Vennero infatti presentate, in
sostituzione della RX e della Arizona, la RTX 125 e la RX Arizona Hawk, entrambe
con motore più potente e componentistica riprogettata al 70%. Le due moto
convissero in listino anche se le preferenze del pubblico tendevano più verso
l’Arizona Hawk, che aveva una “storia” più forte e soprattutto un aspetto e un
nome evocativi di grandi rally.
 
Queste almeno sembrano essere le motivazioni meno razionali e
più emotive che fecero preferire la RX alla RTX. Nel frattempo poi, al Rally di
Sardegna del 1985, la Casa di Arcore si presentò con una moto chiamata RX 250
Arizona Rally, che in realtà altro non era che il prototipo della futura RC
Rally 250, sorella della 125.
 
Tornando alle RX e RTX “stradali”, Entrambi i modelli vennero
proposti con livrea nera o bianca, accoppiata alla sella rossa. In pratica nuove
erano tutte le plastiche, così come venne ridisegnata la strumentazione e venne
aggiunta una piastra paramotore.
 
Rinnovato anche il telaio, la forcella Paioli, il freno a disco da 240 mm, i
cerchi anodizzati in oro (opzionali) e molto altro ancora. Mentre il serbatoio
della RTX rimase da 13 litri come quello della RX, quello della Arizona Hawk
divenne un po’ più piccolo rispetto alla “cisterna” della Arizona: scese infatti
da 22 a 17 litri.
 
A livello meccanico si segnala invece il sistema Power Jet
all’alimentazione e quello BPF (By Pass Feed) che prolungava l’alimentazione in
fase di compressione, oltre a una nuova centralina dell’accensione elettronica a
scarica capacitiva CDI (Capacitor Discharge Ignition) e un diverso impianto di
scarico. La potenza dichiarata salì a 22 CV, erogati a 8.800 giri (25 CV a 7.500
giri per la 200), mentre la velocità massima si attestava sui 125 km/h.
 
Salì anche il prezzo, portandosi a oltre 3.500.000 di lire,
mentre l’avviamento elettrico aumentò il suo prezzo di 100.000 lire in soli due
anni. Le RX aprirono la strada alle successive enduro di Casa Gilera, che di lì
a poco aumentarono sensibilmente l’elenco dei modelli in listino.
