The motor is an air/oil-cooled, transversally 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 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 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.

[1][4] Reviewers pegged the Stelvio as a competent competitor for other adventure-touring bikes like the BMW R1200GS and Yamaha Super Ténéré, although heavy.
