His insatiable thirst for life is only surpassed by his monthly fuel bill. Whether rocketing on land, flying through the air, or jumping the seas, our Road Test Editor does it all and has the scars to prove it.

Aprilia’s V-Four-powered Tuono is the clear benchmark in the liter-class Streetfighter/naked bike segment. And for 2015 it gets even faster with engine displacement growing to 1077cc.

The 78cc increase comes by way of 3mm larger diameter pistons. They are matched to a set of lighter Pankl connecting rods (nearly a pound lighter). Stroke remains unchanged at 52.3mm. Correspondingly, the crankshaft has been modified and features smaller diameter rod pins. The upper half of the engine case is manufactured from a lighter casting and benefits from a more efficient ventilation system to mitigate pumping losses. Aprilia claims a five horsepower increase (175 horsepower measured from the crankshaft) on the dyno. For reference, in our recently published Four-Cylinder Streetfighter Shootout, the Tuono produced 150.9 ponies at the back tire.

As before, the Tuono employs its fabulous Aprilia Performance Ride Control software suite, which includes eight-way adjustable (plus ‘off’) wheel spin (traction), wheelie, and launch control. An electronic quickshifter is also standard. Like the RSV4, the system has been re-calibrated based on information gained from the factory race team’s experience in World Superbike competition.

The chassis also sees a couple of key enhancements highlighted by 0.4-degree sharper steering head angle and a slight reduction in trail. To compensate for its added maneuverability the length of the swingarm was extended by almost a quarter inch. A Sachs steering damper quells headshake during hard acceleration on rough surfaces. The Factory model replaces the RR’s Sachs-sourced suspension (and steering damper) for Ohlins hardware.

Front brake equipment has also been upgraded with a pair of Brembo M432 monobloc calipers biting 320mm diameter cross-drilled stainless-steel discs through stainless-steel hydraulic hoses. Three-way adjustable (plus ‘off’) Bosch 9MP ABS is also standard.

Like the RSV4 RR, both Tuonos get a more aerodynamically efficient upper fairing and a new headlight design that cuts over three pounds from the motorcycle. The height of the rider’s seat was reduced slightly as was the width of the handlebar. Pricing has yet to be confirmed but the motorcycle is scheduled to arrive in U.S. dealers May, 2015.
