MV Agusta has revealed the latest iterations of its Brutale naked sportbikes. Although looking much like the previous 989R and 1078RR, these new editions have been full overhauled with revisions to their four-cylinder engines and significant chassis tweaks.

Both versions use a lighter engine crankcase than before, and both have names that suggest a displacement different than what is actually under the tank. The 990R has a 998cc motor, up from the 982cc 989R via a stroke increase and a bore reduction. The larger and more expensive Brutale, the 1090RR, retains the old 1078RR’s 1098cc displacement. According to factory claims, both models have less peak horsepower, but the 989R receives a slight bump in torque. Both models include a traction-control system, and the RR adds features like a slipper clutch, larger brake rotors and forged aluminum wheels.
