MV Agusta F4 R Race Short 2012, 195 hp for 18,800 euros
MV Agusta F4 today unveiled the new MV Agusta F4 R Short Race 2012 created to give customers a high-performance motorcycle with extreme performance. The Supersport of Varese House takes its name from the new engine “Short Race” capable of extraordinary performance and already used on the F4 RR, the super top of the range of home MV Agusta. The thermodynamic part of 4-cylinder radial valve has been completely redesigned, from the new shaft with low inertia and short stroke that makes possible a very relationship-square bore and stroke.
In this way, the MV Agusta F4 R is capable of reaching speeds worthy of a genuine competition motorcycle. The displacement 998 cc is now achieved with a bore of 79 mm and a stroke of only 50.9 mm resulting in a system of well-13,700 rpm limiter, lowering the linear velocity of the piston (from 24.9 m / s 23 m / s) and thereby improving the reliability. To make the power of approval of 195.2 hp (201 hp against the version super-RR) at 13,000 rpm every detail has taken care of so manic. The magazine uses conducted completely new and bigger valves both intake and exhaust.
For the first time on a large series engine, all valves made from titanium and this made it possible to lower the weight of the same despite the significant increase in diameter (from 28.6 to 31.8 mm for the inlet and 24.6 to 26 for unloading). Breathing engine has optimized thanks to the use of the primary system with a completely new exhaust and manifolds 4-2-1-4 shape with a diameter increased. In addition to ensuring optimized efficiency of the engine, this new exhaust is a protagonist with a unique sound and even more exciting. Power supplied to 4 throttle bodies 49 mm with two injector per cylinder and TSS system (Torque Shift System) variable length intake.
The new engine of the MV Agusta F4 R designed according to the criterion low friction: new report of primary transmission gears made it possible to drastically reduce the speed of the generator and water pump, limiting the absorption power. But there are just new in this remarkable engine, the confirmations come from the removable transmission characteristic that has always distinguished the 4 cylinder MV Agusta and the slipper clutch that ensures the right during the shifting control even more violent. All electronics management has evolved, traction control following new operating modes as well as the two mappings for the engine.
Everything is now controlled by the new command conveniently housed on the left handlebar. The new MV Agusta F4 R is, true to the tradition composite trellis with aluminum side plates. The caster set at 23 ° 5 ‘perfect fit to offer control, maneuverability and stability. Also confirmed the unique single-arm rear, a jewel of engineering that weighs only 5 kg, a record for an item of this type.
The MV Agusta F4 R confirms the best suspension department that already characterizes the earlier edition and has demonstrated its full effectiveness in the field. The upside-down Marzocchi fork, fork with 50 mm diameter unit derived from racing, is adjustable in spring preloaded and hydraulic continuous compression and rebound damping, ultra light forged pin is also made specifically for the F4 R and uses a wheel quick release system, recalling that of the first F4 of history, the legendary Gold Series, which used the same technical solution.
The Sachs monoshock equipped with a nitrogen tank (separated and integrated into the body) and is adjustable in rebound, compression and preload. The linkage allows the strut to raise or lower the rear of the bike depending on the desired buoyancy, the preferences of the pilot and other adjustments made. The Brembo front brake system, monobloc radial calipers, is without doubt the best system for motorcycles on the market today, coupled to a pump with integrated tank designed especially for specific VM.
The Double steel floating disc 320 mm in diameter using a flange and an ultra lightweight thin 5 mm to minimize inertia and unsprung weight. The rear brakes made exclusively for MV, with stainless steel disc 220 mm in diameter and four-piston caliper. The new MV Agusta F4 R , available now at the official sales network, is available in 2 colors: red / gray and white / medium gray at a price of €18,800 euros.
