STELVIO 1200 8V - SOLD OUT
Moto Guzzi STELVIO 1200 8V ABS
The Stelvio 1200 8V boast the latest evolution of the “Quattrovalvole” engine”, introduced in 2006 and universally acknowledged as the most advanced version of the V-shaped 90° transverse twin-cylinder. This highly sophisticated mechanical gem, which is unique in terms of both architecture and engineering clarity, is built using the most advanced components and technical data available.
Worth mentioning on the Stelvio 1200 8V is the raised cam profile single camshaft timing system driven by silent “Morse” type chains” with hydraulic chain tensioners, the forged pistons with three rings cooled by oil jets in the crankcase, the ultra-light valves in special alloy steel with 5mm stems, and the conical valve springs that eliminate resonance and power loss at high engine speeds. Lubrication and cooling are ensured by two coaxial pumps that circulate lubricant through a separate duct in the head up to the exhaust valve seats, where the highest temperatures develop. The cylinders feature an extremely modern design, with the cooling fins tapered toward the front of the cylinders, while the valve covers - which proudly flaunt the “Quattrovalvole” moniker - feature a floating mounting system to reduce mechanical noise.
As far as the fuel system goes, the “Quattrovalvole” engine premiers the new Marelli IWP 189 injectors located on
the intake ducts of the sizeable 50mm throttle bodies, whereas the brand new integrated ignition and injection ECU now exploits the signals sent by the two lambda probes to guarantee adequate fuel metering throughout the entire combustion cycle, improving response to the throttle control, mid range power delivery further to consumptions and emissions. In terms of electronic components, the new Stelvio 1200 8V debuts the ATC system to prevent sliding, an invaluable tool to assist riders keep in control when poor grip conditions arise.
