Registration no. 4260 VH 61
Engine no. 15018
One of the legion of inventive motorcycle firms to be found in France in the 1920s, Lyon-based Ets. Rhony'X were in production from 1924 until 1932 only, with a range which included both low-capacity machines for a more local market and more powerful models, the company using Stainless, J.A.P. and Chaise power-units throughout their ranges. The company's design and cosmetics were noteworthy and Rhony'x gained a favourable reputation well outside the Lyon area.

One of their finest was the very sporting '500', the Model GX. This fast 500, at the effective top of France's capacity range, was made possible by the introduction of the overhead-camshaft, outside-flywheel monobloc 'single' by Chaise in 1927-28, one of a series of advanced engines produced in this period and in tune with the leading edge of development. This unit, with its built-in gearbox, was ideally suited to the Rhony'x sporting ethos, though sales were inevitably limited by the small production and high price of the GX. Survivors are rare.

This Rhony'x Model GX has been part of the collection for eleven years. It is well-restored and complete (save for the rear chain-guard, not present at the time of cataloguing), and has the rear carrier and tool-boxes characteristic of the model as well as a Motul reserve carrier and a period Tan-sad pillion saddle. One of France's fastest and most powerful machines of the period, as well as one of the most technically interesting, it represents a rare opportunity for the discerning collector.

    Les Ets Rhony'X de Lyon, une des innombrables entreprises de construction motocycliste inventives qui fleurirent en France dans les années 1920, produisirent de 1924 à 1932 une gamme incluant à la fois des machines de petite cylindrée pour le marché local et des types plus puissants pour lesquels la firme utilisa des groupes Stainless, J.A.P. et Chaise. Le style et les finitions des Rhony'X étaient très soignés et la marque se forgea une bonne réputation allant bien au-delà de la région lyonnaise.

    Un de leurs meilleurs modèles fut la très sportive « 500 », le Type GX. Cette moto rapide d'une cylindrée maximale pour une machine de production en France dut son apparition à l'introduction du « mono » Chaise à arbre à cames en tête et volant extérieur en 1927-1928, un des moteurs très perfectionnés produits à cette époque et à l'avant-garde de la technique. Ce groupe avec sa boîte en bloc convenait bien à la tendance sportive des Rhony'X, mais les ventes demeurèrent limitées en raison de la faiblesse de la production et du prix élevé de la GX. Les survivantes sont donc rares.

    Cette Rhony'X Type GX fait partie de la collection depuis 11 ans. Bien restaurée et complète (sauf le carter de chaîne secondaire absent au moment de la rédaction de ce catalogue), elle possède le porte-accessoire et le coffret à outils typiques du modèle ainsi qu'un porte-bidon de réserve Motul et un tan-sad d'époque. Cette moto française, une des plus rapides et des plus puissantes en son temps et une des plus intéressantes du point de vue technique, est une rareté absolue sur le marché de la collection.
