2009 Moto Guzzi Stelvio 1200 User Ratings

TheMoto Guzzi Stelvio 1200 is a highly sophisticated mechanical gem, which is unique in terms of both architecture and engineering clarity, is built using advanced componentry and technical solutions. These include the single overhead camshaft driven by Morse chains with a hydraulic tensioner, the forged pistons with 3 piston rings, cooled by oil jets in the crankcase, ultra-light valves with 5 mm stems and conical valve springs that eliminate resonance and power loss at high engine speeds. The engine is lubricated and cooled by two separate oil circuits, with two coaxial gear driven pumps. In the cooling circuit, engine oil is fed via separate conduits in the head to reach the exhaust valve seats - where the highest temperatures are generated - and the heat is then dissipated by an oil cooler, which is located at the front of the engine for maximum exposure to the air flow. The lubrication circuit feeds all the vital organs of the engine, such as the crankshaft and connecting rod bearings and the valve timing components.
