We want one ASAP. No questions asked. This beautiful bike is a CR&S DUU. Enough said 
The CR&S DUU is a unique model around the world’s motorcycle context. It was born in the CR&S workshop, the small Milanese factory which is known for the refinement and the exclusivity of its own creations. But above all, because of for the first time two motorcyclist excellences are gathered: Italian sporty rolling chassis and design powered by a muscular American big-twin. The American big displacement engine’s attraction, and particularly its muscular torque, doesn’t have any equivalent at all. One look at the engine’s fins is enough to be seduced by such a pure shape, devoid of radiator. And for a lot of motorcycles fans, the air cooling system and the pushrod distribution are elements issued from a rich historical past.
But it is not a model born only for the huge American open roads. The chassis and its handling performances are much more evolved than what can be thought. These parts have been engineered and designed to warrant a complete riding satisfaction on every kind of routes, even on fast bends or mountain’s narrow roads. The DUU is an innovative motorcycle, “modular and muscular”, with durable materials and components, equipped with a powerful, rugged and reliable engine.
The DUU’s harmonious and innovative shapes surround those mechanical parts, selected only for their qualities.
1-Engine
Two pushrod head valves per cylinder with hydraulic self adjustment, three belt driven camshafts (one intake and two exhaust). One piece machined crankshaft with twin conrods. ECU developed by S&S. It’s a traditional engine, but built with modern technologies and materials, produced by S&S Cycles, leader in manufacturing high performances pushrod American “V” twins. Catalyzed stainless steel exhaust system with 2 lambdas. Baker gearbox available with 5 or 6 speeds.
This 117c.i. (1916 cc) X – Wedge engine is the DUU’s « heart ». An engine designed to give a strong and usable power from low revs and above all, an unbeatable huge torque : from 2.500 until 4.700 rpm, the torque available is always over 140Nm, with a totally flat dyno curve.
2 – The rolling chassis
The chassis has a compound structure. The main element consists in a stainless steel high section tube (107,5 mm), same quality as the one used for oil pipelines. It’s a backbone chassis working also partially as fuel tank. All the other chassis’ elements are made in stainless steel and manually TIG welded. The stainless steel chassis has been chosen to avoid corrosion for life, and it enables excellent finishes. All these chassis components are connected together by light alloy parts, all machined from solid. The seat holder light alloy box structure, a CR&S’ patent, is manually TIG welded and used partially as gas tank, keeping the fuel pump, the battery, the ECU, and the main electric accessories.
The single side swingarm is made in a big section stainless steel tube too (90 mm), reinforced with stainless steel welded structure box. Everything is totally TIG manually welded. The light alloy fork yokes are machined from solid. The two seats version’s shock absorber has a fast manually adjustable spring preload. The standard compound wheels are made in light alloy with casted hubs. The CR&S’ compound wheels have machined from solid light alloy hubs and light alloy rims. The rear tire size is 190/55X17″ and the front one is 120/70X17″. This tires’ size has been chosen to offer the best sporty handling capabilities available, performing top riding control on each kind of routes (max lean angle 43°) : they are radial tires, with sport-racing compound (the rear one has three zone compound).
This is the agile « body » of the DUU: a sporty rolling chassis, top components and top materials give to the DUU safe and fast rides without forcing.
3 – Body
The structural components are made in carbon. The others are made in VTR, ABS or carbon. The gas tank is divided in two parts : the chassis’ backbone and the seat holder box structure. Some body’s parts have an specific aerodynamic function enabling a better flow channeling to favor the vehicle’s efficacy, the cooling of the mechanic parts and the pilot’s comfort.
This is the DUU’s « skin »: technological and minimalistic, but functional as the same time. A balanced mix that makes this body unique.
DUU “Deperlù” (Solo)
DUU “Conlatusa” (Two seater)
CR&S DUU “Sbirluscenta”
CR&S DUU “Grisa”
CR&S DUU “Nera”
These are the models offered from the DUU line up – and with the price of 19000 to 21000 euro – this is one sweet deal for the motorcycle like this.
