New 2012 MV Agusta F4 R Corsa Corta debuts

Not to be confused with the company’s flagship F4 RR model that debuted earlier this year, MV Agusta has released info on the F4 R Corsa Corta, intended to be the “standard” new generation F4 model with a slightly less premium price. Using the same all-new short-stroke engine (79 x 50.9mm versus the old 76.0 x 55.0mm measurements of the previous F4 powerplant) as the full-monty F4RR, the F4R’s engine output is slightly downgraded from the F4 RR’s claimed 201 horsepower at the crankshaft to an only slightly more reasonable 195.2 horsepower at 13,000 rpm. Most of this is achieved through engine mapping changes, as everything else in the engine—including the TSS variable-length intake, larger titanium valves, etc.—is basically identical.

As you’d expect for the less premium version of the MV, the suspension has been swapped from the F4 RR’s pricey Öhlins componentry to a fully adjustable Marzocchi 50mm inverted fork and Sachs rear shock. Wheels have been changed from the forged aluminum hoops of the F4 RR to more wallet-palatable cast aluminum units. Other detail changes include a fixed steering head angle and swingarm pivot (whereas the F4 RR’s steering angle can be moved one degree in either direction from the stock 23.5 degree angle, and the swingarm pivot can be moved within a 3mm range, both with machined inserts), a non- Öhlins steering damper, and MAG welding instead of TIG welding (Tungsten Inert Gas welding provides a slightly stronger weld) on the steel trellis portion of the hybrid steel/aluminum frame.
