As exclusive and expensive as MV Agusta's base models are, they've always been complemented by limited-edition specials with fancy names. Taking a page from Harley's playbook, the Varese, Italy-based company turned the tables for 2010, giving customers the ability to special-order the bike of their dreams from an extensive collection of more than 50 accessories. The most intriguing option is the $5880 Cannonball Engine Kit, which includes the new F4's radial-valve cylinder head, different intake and exhaust cams, a remapped ECU, STM slipper clutch and an ultra-lightweight titanium race pipe that undercuts the bike's standard system by 14 lbs. Purchased individually, all of these pieces would cost a staggering $9234. Count on about 10 hours of highly skilled labor to turn a regular 1090RR into a fire-breathing Cannonball.
