Las JJ Cobas de Trial
"La 350 de trial fuer el primer proyecto que
abordé dentro de la nueva sociedad JJ Cobas, mientras procuraba darle esporadicamente una mano a Cardús con la Kobas MR1 en su imparable carrera hacia el título Europeo..."
"A pesar de todo, mi apoyo tuvo un carácter meramente "didactico", adiestrando a Carlos en el reglaje óptimo de las suspenciones. Realmente, no me parecia ético
estar muy metido en la preparacion de una moto hecha para otro cliente..."
El proyecto no era ninguna bicoca. La JJ Cobas de trial experimentó distintas fases de desarrollo:
RC 1, RC 2, RC 3, o por decirlo de otra manera: gama 10, gama 20 y gama 30.
"La RC 1, que a efectos internos denominaríamos RC 10 no paso de ser un simple planteamiento de plano, que permitió hacer las primeras pruebas sobre el mismo papel para llegar a la RC 11 y
,
más tarde a la RC 2, previas modificaciones para albergar un filtro de aire de mayor volumen que, a la postre, obligaría a variar tambien la forma del subchasis trasero y la viga del
bastidor.
La RC 2 fue la primera moto que empezo a correr con motor Montesa. Las primeras unidades con propulsion Bultaco serían las RC 25 y RC 26 , y la ultima la RC 35, mientras la moto que se puso a la
venta, siempre con propulsores Montesa, corresponden más exactamente a la especificación RC 31.
English version: JJ COBAS TRIAL BIKES
“The 350 trial bike was my first project at the new company JJ Cobas. Meanwhile, I was
occasionally helping Cardús with the Kobas MR1 in his unstoppable race towards the European title...”
“Despite everything, my support was purely educational. I was training Carlos in the optimal
setting of the suspensions. In fact, I didn’t think it ethical to be involved in the preparation of a
motorcycle that was made for another customer...”
The project wasn’t a piece of cake. The JJ Cobas trial bike underwent several stages of
development. RC 1, RC 2, RC 3, or so to speak: range 10, range 20, and range 30.
‘RC 1, which we would call RC 10 for internal purposes, was only a blueprint concept. It allowed us to carry out the first tests on paper, which brought us to build the RC 11 and, later on, the RC2. We made adjustments to fit a larger air filter and, in the end, this would also require changing the shape of the rear sub-chassis and the frame beam.’
The RC 2 was the first bike that had a Montesa engine. The first units with Bultaco engine were RC 25 and RC 26, and the last one was the RC 35. The motorcycle that was sold –always with a Montesa engine– had, to be accurate, the RC 31 specs.

La otra moto de trial
La Montesa N4A, prototipo que diseño A.Cobas conjuntamente con los tecnicos de montesa y que dieron paso a la construccion de la Campeona del mundo de Marc Colomer.
English version: THE OTHER TRIAL BIKE
The N4A Montesa was a prototype that A. Cobas designed together with Montesa’s technicians.
It brought them to build the world champion bike driven by Marc Colomer.
