Brutale Tech
For the 990R, cylinder bore has actually decreased from 79 to 76mm, while the piston actually travels farther in the cylinder-stroke increases from 50 to 55mm. The 1090RR bore is 79mm with the same 55mm stroke. To quell vibrations, a balance shaft is now added to the front of the engine, driven directly by the transmission's primary gear. Stability is improved by way of a 20mm longer swingarm. Rear wheel sees a new cush drive to dampen driveline lash, as well as a new hub and bearing for less rolling resistance. Further weight savings for the water pump slices another 60 grams. The redesign also includes a redesigned impellor with new sealing that flows 65-percent more coolant than before. Cylinder head remains the same, with the same radial valves we're used to seeing on MVs, but now the Brutale gets a little help from Japan with new 46mm Mikuni throttle bodies. Injection is still via a single injector, calibrated with Marelli electronics. The new Marelli brain, coupled with the Mikuni throttle bodies is supposed to hold the answer to the abrupt throttle response. Improved lubrication was one of the design goals for the Brutale's. To do that, the oil filter was first relocated to the bottom of the sump, making filter changes easier. The oil pump intake was also located deeper in the sump for improved performance under heavy braking. The entire assembly shaves 0.6 kg from the previous version. '10 MV AGUSTA 990R/1090RR
