Since the 1990s, due to the low overall maintenance cost of medium and high displacement single-cylinder engines, coupled with the fact that light and torque-rich fun is difficult to replace, it has been popular in many second-round events in Europe – among which the "Sound of Single" held in Italy is not only one of the best heavyweight events in this field, but also gave birth to unique commercially available single-cylinder sports cars such as ducati Supermono and BIMOTA BB1. In modern times, although this spirit also has the continuation of Moto3 and other events, but in terms of commercially available cars, due to environmental protection regulations, large-displacement single-cylinder sports cars have finally been forced to leave the historical stage, even KTM, which specializes in single-cylinder and two-cylinder models, does not seem to have signs of expanding the single-cylinder RC series to more than 390c .c.
DUCATI Supermono was the unsurpassed king foal in that year's single-cylinder event.
However, although today's KTM does not produce a mid-range single-cylinder sports car, for the modifier, it is certainly not a fantasy to make a compact "covered steel cannon", so the modifier Christopher Carlotti has created a "Frankenstein car" - starting from KTM's 690c .c. single-cylinder engine, while streaming and combining a large number of existing premium car components, and named RC690 Supermono!

In fact, the heart of this speed machine comes from a damaged 2013 KTM 690 Duke with a still intact power system. After removing the engine and other related components, Christopher Carlotti temporarily attached it to the compact wrap-around frame of the CAGIVA Mito 125 with the bracket of the earthen gun, and tried to match the SHOWA fork of the DUCATI 749 and the rear single-gun shock of the BMW S1000RR – of course, both of which were fully adjustable and fully supported the body and engine of the light steel gun.

After the completion of the fake, Christopher Carlotti also determined that the idea was feasible, so he began to make a formal engine lock point, and even transplanted the water cooling system of the 690 Duke, along with the gasoline pump of the giant PIERBURG and the pump pressure regulator on the DUCATI 851. The hull and gas collector are handcrafted by Christopher Carlotti from fiberglass, which is designed to be easily removed from the air filter. Finally, the braking system also follows the single disc setting on the CAGIVA Mito 125, but the relevant components have been replaced and the calipers have been changed to radial form, presenting a perfect balance between lightness and braking power.
A lot of flow and ingenuity, and finally created a highly complete handmade work.
After the masterpiece was completed, Christopher Carlotti also took it to the Castelleto circuit in Italy for testing – after opening and pressing the starter button to replace the keyhole, the extremely powerful single-cylinder engines began to roar. Christopher Carlotti's carefully tuned Knight Triangle, with the RC690 Supermono's light body weight of only 141kg dry weight, and the tire sizes of the front 110 and rear 150, does bring precise directivity, and quick direction change between corners is also a piece of cake, so it can be said that the production team successfully completed the vision of creating a light track machine.
