2013 MV Agusta F3 аввал савор

In the face of the global sportbike sales slump, Дӯкони Италия бренди мотосикл MV Agusta аст иштиёқ барои зинда гардонидани бозори Middleweight supersport рукуд бо F3 ба наздикӣ аз чоп он. Садо муҳаррики сегона-силиндраи 675cc ултра-паймон, дар F3 ($13,999) аст, Аврупо каси дигарро дар бораи беҳтарин роҳи аз олитарин меоянд, ба олитарин.

VISION BECOMES REALITY

Born four years earlier, Дар F3 хоб дер президенти MV аст, Клаудио Castiglioni, ки sportbike се-силиндраи пеш аз гузарон тобистони соли гузашта аз бемории саратон мавриди баҳрабардорӣ қарор. Бо дарназардошти таърихи хеле реша давонда он дар гонкиро роҳ, дастгоҳу барои рақобат ва талаботи Supersport ҷаҳон сохта шуда буд, - як қатор гонкиро ҷаҳонӣ, ки MV нақша барои рақобат дар барвақттар мавсими ҳамчун оянда. Дар барзиёд 20 миллион евро ба лоиҳа бо тамоми тарҳи дар хонаи дар қароргоҳи MV дар шимоли Италия амалӣ funneled шуд.

Дар аслӣ аз F3 аст моеъ сард,, Inline муҳаррик се-силиндраи бо як сари 12-халќи (тамоми таљњизоти мањкамкунанда аз титан, дурӯғе) кушуд аз тарафи camshafts-занҷираи ронда дугоникҳо,. Ҳар як силиндраи мебарад ҳаққонияти ва зуд нисбатан беш аз мураббаъ андозаи 79.0 х 45.9mm, squeezing пардохти сӯзишворӣ таносуби ба 13:1. Дар муҳаррик дар поёни-охири кор таъмин як тарҳи беназир, ки дар он crankshaft spins аќиб.

Ин кӯмак безарар inertia пеш аз мотосикл ҳаракат дар қабули он maneuverable бештар бо суръати баланд муҳаррики, MV мегӯяд.

Мисли ҳама чиз Италия, form follows function and the profile of the motor is one of sleekest and minimalist we’ve seen on a street bike to date. Both the water and oil pumps are integrated into the engine block, as is the cooling passages, so the only external fittings are for connecting the stacked radiators (one water and one oil).

A cable-actuated wet-style clutch (without mechanical back torque functionality, more on that later…) and a six-speed gearbox (with quickshifter) gets the power to the back wheel. Exhaust gasses are purged via an elegant low-slung exhaust that terminates into three slash-cut pipes behind the rider’s right foot.

The engine is controlled by a sophisticated electronic ride-by-wire management system that does away with the physical cable connection between the throttle and intake. The system monitors a number of atmospheric and engine-operating factors that allow for near perfect running conditions. The nearly vertical intake tract uses a pair of fuel injectors and a 50mm throttle body for each cylinder.

There’s also a lean-angle sensor and rear-wheel-speed sensor to supplement the traction/wheelie/launch control.

Additional functionality comes in the form of engine/throttle mode adjustment. Four settings are offered: борон, Normal, Sport and a Custom map that allows the rider to configure Gas Sensitivity (throttle response), Engine Braking (Sport or Normal), Maximum Torque (Sport or Rain), Engine Response (Fast or Slow), and rpm Limiter (Sport or Normal), all independently of one another.

Weight distribution and packaging was a key design concept and engineers were tasked with cramming components within the smallest area possible. The main frame is fabricated from steel tubes that merge to aluminum spars where the swingarm attaches (also fabricated from aluminum and single-sided). Wheelbase measures 54.23 инч, which is right inline with many of the Japanese 600s.

A 43mm Marzocchi inverted fork takes care of front suspension duties while a Sachs gas-charged shock provides rear damping. The 4.22-gallon fuel tank is positioned above the airbox but stretches beneath the rider’s seat – further enhancing center of gravity. Braking components consist of Brembo two-piece radial-mount calipers paired to a pair of 320mm discs.

The calipers are powered by a Nissin radial-pump master cylinder. A 220mm disc and twin-piston Brembo caliper control rear wheel speed during deceleration. No ABS option is available.

MV claims that the F3 weighs around 420 pounds ready to ride.

Swing a leg over the F3 and the riding position proves to be relatively forgiving for a bike designed for competition. The bike feels a bit long from front-to-back, but the seating position isn’t quite as stretched out as other bikes in its class. With a seat height of just under 32 inches it’s also low to the ground.

Indeed it’s narrow, but not overly so and the size of the fuel tank is still substantial enough to give the rider area to squeeze and hold on to during braking and cornering maneuvers. The windscreen isn’t the tallest but still does an acceptable job of deflecting air around the rider. Riders of above average height will encounter difficulty getting a clean tuck as the seat is so short that you can’t scoot far enough back to get completely behind the bubble.

Getting rolling from a stop requires a bit of clutch finesse as first gear is tall but after the quickshifter makes it simple to upshift into the next gear. The clutch lever offers a light pull and also a decent amount of engagement feel.

Right off the bottom the F3 isn’t the fastest thing on the road but the engine revs quick and by 10,000 rpm it’s producing some serious thrust. With the throttle pinned, power steadily builds all the way to its 15,000-rpm redline, which equates to a relatively wide powerband for a middleweight. There’s no surge or heavy hit of top-end power that typically defines the Supersport class, but that’s all right by us.

Having not ridden a Supersport in quite some time, probably the biggest testament to the F3’s engine performance is that it never felt slow, which is dang impressive. Due to time and machinery limitations we never got to play with the eight-way adjustable traction control, wheelie control or launch control systems.

The character and overall sound of the engine is excellent with it delivering a deeper howl than expected with its engine displacement. The engine also felt balanced with minimal vibration at all rpm. With Sport mode selected the throttle did feel jerky and overly responsive, which will make it more challenging to control.

MV Agusta F3

Normal mode offered a more standard-feeling calibration, but with a soft rev-limit interruption near redline.

The transmission gear ratios and final drive gearing felt spot-on and we were surprised by how much attention the gearshift lever needed. Not a bad thing at all and a testament to how well optimized the powertrain is to maximize acceleration force. Even though the F3 doesn’t employ a mechanical slipper clutch, its electronic Engine Braking functionality is so well dialed under deceleration that we didn’t even know that it was lacking the hard part until they told us after the test.

While we loved the F3’s engine and drivetrain performance its handling proved to be more difficult to read. It steers into high- and low-speed corners with minimal effort and it’s predictable. The problem for our test was that MV chose to run Dunlop Sportmax Q2 tires instead of the OE-fitted PirelliDiablo Rosso Corsa tire – and the change affected the chassis geometry, which made the bike handle awkwardly mid-corner.

It also had a tendency to headshake at certain points on the track.

In spite of its awkward handling, the F3’s suspension surprised us by how well it functions. Under braking the fork is very responsive and offers minimal stiction initially in its stroke. It also has a very progressive feel with no weird spikes or hang-ups as it was loaded with the front brake.


Conversely the rear suspension also performed well and we were taken back by how well the back end of the bike ‘hooked up’ under heavy throttle loads.

We also had mixed results with the brakes. When the bikes were fresh in the morning the brakes performed without flaw, delivering a high amount of lever feel and stopping power. I was actually surprised by how much more effective its two-piece Brembo calipers were as compared to other bikes with similar set-ups.

But as the day went on the brakes on the red bike I was riding developed a shutter that made it unnerving to operate.

For its first foray into the world of modern middleweight sportbikes, MV has done an admirable job considering its limited resources. For sure it’s got a strong, well-sorted powertrain package that can run with the best from Japan and Europe. The ergonomics are functional as well – for all but us taller folks.

But the thing that really holds the MV back at this point is a bit of chassis refinement. Get that dialed-in and there’s little doubt that it could be a true contender in the class.
