The 2009 model featured changes in engine tuning. For 2012, the fairing was restyled; electronic dash updated; and fuel capacity was increased.
The so-called Quattrovalvole (four-valve) engine comes from the Griso/Breva series and has been optimized with modified camshafts for an improved torque curve.
The motor is an air/oil-cooled, longitudinally mounted 90° V-twin, four-stroke engine that displaces 1,151 cc (70.2 cu in) and generates rated output of 79.4 kW (106.5 hp) at 7,500 rpm. The maximum torque of 113 N·m (83 lbf·ft) is developed at 5,800 rpm. The two cylinders have a bore of 95 mm (3.74 inches), the piston has a stroke of 81.2 mm (3.20 inches) and a compression ratio of 11:1. Each cylinder head has an overhead chain driven camshaft that actuates the two intake and two exhaust valves.
The 2-into-1 exhaust system made of stainless steel and has a three-way catalytic converter with two oxygen sensors; the emissions are well below the Euro 3 standard. The fuel tank on both the base model and the NTX variant holds 32 litres (7.0 imp gal; 8.5 US gal), of which 7 litres (1.5 imp gal; 1.8 US gal) is reserve. The manufacturer recommends the use of unleaded gasoline with an octane rating of at least 95.
The chassis consists of a tubular steel frame with load-bearing engine. A hydraulic 50 mm diameter upside-down fork by Marzocchi with 170 mm (6.7 inches) of travel guides the front. The rear wheel is held by a single-sided swingarm with progressive linkage, which is damped by a Sachs-Boge monoshock with a progressively-acting lever system and 155 mm of travel. Power is transferred to the rear wheel via a shaft integrated into the single-sided swingarm with two joints and an anti-torque reaction support.
The front wheel mounts dual disc brakes with cross-drilled, semi-floating 320 mm steel discs and radial-mounted four-piston calipers. At the rear wheel, a cross-drilled 282 mm disc with a dual-piston caliper is mounted. The brake lines are steel reinforced. The brake system on the latest models has standard anti-lock brakes and a switchable traction control system.
Reviewers pegged the Stelvio as a competent competitor for other adventure-touring bikes like the BMW R1200GS and Yamaha Super Ténéré, although heavy. They noted in particular the ability of the NTX, with its high capacity fuel tank, to take riders to offroad destinations where refueling is not available.

- Kevin Ash (June 30, 2011), "Moto Guzzi Stelvio 8V review", The Telegraph, retrieved 2013-04-10, "[W]hat has corrected the range problem, is the fitment of a seven-gallon (32-litre) fuel tank... it should be possible to nudge 300 miles before running dry. This is important to touring riders, especially in more remote areas at weekends..."
- Mark Tuttle (September 4, 2012), "Road Test: 2012 Moto Guzzi Stelvio NTX", Rider, "[W]hile you may not need an 8.5-gallon gas tank, having one on the 2012 Moto Guzzi Stelvio 1200 NTX does help reinforce its claim to real adventure-tourer status."

- 2Räder (6/2012), "The big Moto Guzzi is for people who want to stay with an air-cooled two-cylinder, but will not ride a German Enduro — with modern motorcycles there remains only the Stelvio. Its dimensions are as formidable as those of the blue-and-white market peer, and the weight is even higher. [Translated from original German.]"
