Fast by Ferracci MV Agusta F4
Fast Forward for the 750cc Four

Moto-Euro Fall Issue-05There’s a consensus among industry insiders and enthusiasts regarding this machine. Most agree that not only is it the world’s most majestic production motorcycle, but its numerous technical and engineering aspects combine to place the rapid Italian in the rarified air of a modern icon. The Castiglioni-backed, Tamburini-designed classic very well could have been badged a Cagiva or even a Ducati, but the timing was right for the Italian brothers to place upon it the most revered moniker in all of motorcycling: MV Agusta. Not unlike its forebearers, the F4 delivers in ways that numbers and graphs cannot measure, and since its late 1998 introduction, the MV has upheld its famous name by being the most desirable and exclusive sporting weapon offered anywhere.

Naturally, the cost factor of the MV weighs heavily into the equation, and the limiting outlay is something only the buyer can decide. But membership has its privileges, and because of its very high build quality and low production status, resale for the MV Agusta remains strong. Like the ultra-desirable Verghera fours, the collectability element must be factored in, as the F4’s value will only drop so far before it begins to rise again.

Due to the upgrades engineered into the latest incarnation (now liter-sized and 160-plus horsepower strong), the newest version mixes dollops of newfound horsepower with the tactical precision and breathtaking lines the F4 is best known for. As a result, a notable performance gap has opened between it and the first edition machines, leaving the buyer no choice but to ante up for that newfound CRC thunder. Until now. What if another option existed? One way of gaining back much of that extra capability would be to use the more affordable, but no less beautiful, 750/F4 as a base. Just for reference, the standard 1000 F4 retails at $21,500 while the titanium fitted, carbon fiber sheathed limited production F4 Tamburini comes in at a checkbook-flattening $42,695. Do we have your attention?

Widely known and respected in an industry he helped form, when Eraldo Ferracci gets involved, everyone pays attention. Although Ferracci generally brushes it off, the fruits of his R&D work have a habit of appearing later as production standards. If you don’t believe that, chart the evolution of the 4-valve Desmo against the Fast by Ferracci specials that generally preceded them. “A good tuner looks for simple ways to improve,” Ferracci said from his desk in Willow Grove, Pennsylvania. “But it’s generally more than bolting on a pipe or plugging in a module. You must have the experience, the contacts and the resources to do it right.” Before our last FBF project was complete (“Nuovo Thunder,” M-E Spring ‘03), Eraldo was planning the next one. “We’re developing a big-bore kit for the MV,” he told us over dinner, after learning the publisher kept one in his garage. “You should send that next.” With the tire-blistering horsepower the crew at FBF breathed into M-E’s Project V11 still fresh in our minds, plans were made to ship the MV due east.

Measuring 45.7 cubic inches, MV’s liquid-cooled multi features chain-driven double-overhead cams and four valves set in a radial combustion chamber. A Weber Marelli fuel injection system and ECU mix spark, atmosphere and fuel, with power delivered through a cassette-type, six-speed gearbox and wet clutch. In the Evo series, the engine was given its first upgrade with new Malhe-made forged pistons and cylinder block. It has a lighter crankshaft, redesigned combustion chamber and valves met with new variable rate springs, under-piston cooling jets and a beefier clutch. Although the MV four is painstakingly engineered and extremely compact, it exists in classical inline form. As delivered, our early (MY 2000) F4 produced a crankshaft rated 137 hp at 12,600 rpm.

Ferracci began the initial stages of his big-bore MV Agusta kit in 2003. Because of his close working relationship with both the factory and its U.S. importer (his son, Larry Ferracci is the President of nearby Cagiva USA), Ferracci enjoys an undisturbed path to whatever he needs for the task. An old hot-rodder at heart, Ferracci knows the quickest way to more power is additional capacity, but the “big bore” term is an overstatement. FBF’s kit features pistons only 2.2 mm larger in diameter than the stock slugs. After a close examination and study of the 749cc cylinder, Ferracci decided the minimal increase offered by the carefully balanced Wiseco-made pistons was a good compromise. The 76 mm, gas-ported, forged pistons bump displacement to 800cc and compression is raised to 13:1. Piston weight was matched with the stock units, thus eliminating the need to rebalance the crankshaft assembly. “It’s a 50cc increase,” says Ferracci, “but it is an important increment, with useful cylinder filling. The piston kit is only the start; and combining that with other key components will help us reach our overall objectives.”

Ferracci is a strong believer in balanced performance, so our MV was fitted with a carefully orchestrated mix of aftermarket and hand picked items from MV’s Special Parts Catalog. It’s advertised as a drop in, but to install the piston kit the engine must be removed, which constitutes a complete teardown. A bored, re-coated and diamond-honed cylinder was swapped for the original, then a single piston and cylinder head is fitted and checked for clearance. Because the kit makes use of the stock crankshaft, connecting rods, cams and valve gear, after plugging in the Power Commander III, the engine is assembled and lifted back into place. The remaining work can be carried out with the engine installed.

While Eraldo and his team attended to their respective tuning chores, we turned our attention to other areas of the project. To trim some weight and add panache, FBF (via MV Special Parts) supplied a full set of carbon fiber bodywork. Acting on a tip from Paul Montgomery at Pro Italia, we delivered the “black gold” to Jacques Levy at GP Motosport with a specific scheme. Our kit consisted of the upper faring and side panels, the belly pan, two airbox covers and the single seat tail faring. “That is some of the highest quality carbon fiber I’ve ever seen,” said Levy. “It’s extremely thin, strong and very straight. Just beautiful. Much of what’s available is poorly made; surprising, considering the cost of this stuff.” Formed in a mold, a release agent is needed to break the part free and, according to Levy, that chemical causes the biggest problem. “No matter how fastidious the preparation, the release agent stays in the cracks and crevices. If you miss a spot, small holes or ‘fish eyes’ appear in the finish. That was the challenge on the ‘see through’ sections and panels, which are basically clear coated after many hours of cleaning and block sanding. I use a needle to fix the individual spots, but it’s very time consuming.”

Levy sprayed the black sections of our MV with Dupont products. Two coats of block sanded, premium PCL primer was covered with two more coats of “chromium” gloss black, more block sanding, then a clear coat. “I spray it on thick,” smiled Levy, who shared the “secret” of the carbon fiber lettering found on our now-sinister looking MV Agusta. “I estimated it would take two guys and two weeks, start to finish, but I lost track of the time. I’m pleased, especially regarding the commemorative lettering. Eraldo Ferracci is a motorcycling legend. It was a thrill to be involved with one of his specials.”

Knowing our FBF F4 would run hard and look good doing it, Jeff Gehrs from Brake Tech stepped in with a set of his new “AXIS” cast iron floating rotors: 310 mm front and a 210 mm rear. Featuring hard anodized carriers, the newly optimized petal design is cryogenically processed for maximum performance and thermal stability and substantial weight savings. Brake Tech’s AXIS rotors represent nearly two years of intense research. “The philosophy behind the development,” says Gehrs, “was taking a step back to analyze precisely and fundamentally how a floating rotor works. It became evident that the traditional floating button was used as the load bearing mechanism for transferring these substantial forces. Not only is that inefficient, but it’s destined for high wear and distortion. Our patented and lightweight system very effectively allows the floater button to carry out only its intended purpose. The braking forces are handled by our trademarked Direct-Link system. It is truly form following function.” CNC-cut from U.S. made Alcoa or Kaiser aircraft grade aluminum, these ultra-light, vented rotors disperse heat quickly and evenly for maximum efficiency.

As the project evolved, the progressive successes Eraldo and his team at FBF enjoyed spurred them to keep tinkering. Using the latest version of DynoJet’s software package, dyno-tuning takes much less time than it used to. Still, Ferracci must be acknowledged as the True and Rightful master of the dyno room. Preliminary tuning had the bike nudging the 140 hp mark, giving the F4 nearly 30 additional rear-wheel horsepower over its stock test figure. Perhaps more important was the boosted torque, up **** , which cured perhaps the design’s most obvious shortcoming. Astounding, when you consider that besides the pistons, Power Commander, a less restrictive SPR header and the Ferracci/BMC Air Power performance airbox, the engine is otherwise factory stock. As a result, our MV Agusta gained a whole new personality, not the least of which was the authoritative bark emitting from the quartet of carbon-wrapped, FBF cans. With more power everywhere, Ferracci exercised caution before our first track test. “Never exit a low speed corner hard in first gear,” he warned. “You’ll light up the rear tire and lose the bike. It has much more power and torque than you’re used to. You’ll need to learn how to ride it all over again.”

That process was eased slightly by the addition of several more items from Ferracci’s catalog. At nearly $900, FBF’s new slipper clutch might seem excessive, but one misjudged downshift is all it takes to enlighten one to its true value. A distinct improvement came by the fitment of Ferracci’s handlebar riser kit, featuring a revised angle that eliminates the smashed-thumbs-at-full-lock dilemma. Playing the part of the mad scientist, Ferracci then installed an electronic Quick Shifter. Interfacing with a dedicated USB port in the PC III, activation cuts fuel for a millisecond, allowing clutchless upshifts. Programmable, ours is set to engage at 4000 rpm, at which time you may bang away to your hearts content, or shift normally. Our first post-Ferracci trackday at legendary Pocono Raceway in upstate Pennsylvania revealed to us Eraldo Ferracci’s ultimate goal for the project. The MV was simply transformed; its ability to gather speed is so effortless, mating the uprated braking (and a fresh set of Corsa Diablos) with the machine’s inherent balance provides the rider with more confidence than ever. Our F4 is smoother, incredibly precise and—believe it—brutally quick.

Perusing through various internet and print classifieds revealed prices ranging between $10-14K for used F4 sport bikes, and roughly 25% less for comparative Brutale nakeds. While our example is admittedly over the top with full CF bodywork, cutting edge braking components and accessory overkill, the horsepower per-dollar scale remains decidedly in our favor. In lieu of MV’s quintessential sporting hardware, we’ve proved the dedicated owner can acquire 90% of that machine’s capability by opting for FBF’s 800 kit, then allowing Eraldo to tweak it. When asked if retrofitting 750 F4s that challenge—or often surpass—the performance superiority of the 1000 F4 was a conflict of interest for Ferracci, his reply was genuine. “It’s an enthusiast’s slant,” said the fabled tuner. “We do this because we can, or have been asked to do it. The MV Agusta family can tolerate upgraded F4s. The older machines are not obsolete. They are still desirable.”

Thanks to Ferracci, that appeal is greater than ever. For owners questioning the logic of modifying a collectable and affecting its future value, take a moment to recall former race chief Arturo Magni of the old works in Verghera. Even before MV closed its motorcycle division, by 1977 Magni was busy manufacturing chain-drive conversations, Siamese exhausts and big-bore engine kits for dedicated owners. You’ll pay dearly for that red and silver 750S America, but be prepared to add a rain bucket of one hundred-dollar bills for any machine fitted with Magni’s performance upgrades. In the same way that Magni is accepted and revered, Ferracci, a proven, esteemed tuner with four Superbike titles and deep industry connections, is likewise acknowledged. It is difficult to express the standards of excellence and dedication displayed by Eraldo and his team at Fast by Ferracci, but one clue to their competence is a refusal to rest upon their laurels. For those passionate about MV Agusta but who find the current wares out of reach, welcome to the inner circle. If MV ownership is your dream, a Fast by Ferracci MV should be your goal. Whether your F4 is used and abused or a well cared for original, your fast forward awaits.
