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.
- The machine is now offered with a Certificat d'immatriculation.
