Aprilia RSV4 Biaggi Replica: 200bhp doesn't equal homologation special

Galleries -


Making 200bhp and 92lb/ft of torque (+20bhp and 7.4lb/ft) you might think the Aprilia RSV4 Biaggi Replica is an homologation special intended to legalize Max’s gear-driven cams, underseat fuel tank and trick swingarm. It isn’t, rather it benefits from certain SBK-spec components and electronics to create the ultimate privateer or track day Aprilia.

Update: According to Aprilia, the Biaggi rep will not be sold in the USA.
Here’s what the Biaggi Replica adds to the Aprilia RSV4 Factory:

Pressurized gas Ohlins forks; trick top yoke; an SBK-spec Ohlins TTX36
shock with progressive linkage; Ohlins steering damper.

Marchesini 7-spoke forged magnesium wheels; front: 3.5×16.5″, rear:

Pirelli Diablo SBK in 120/75 (front), 190/65 (rear).

Cassette style with quick shifter.

Titanium Akrapovich 4-2-1 full system.

APX2 ECU capable of customizing variable-length intake ducts, engine
maps, traction control, engine braking, gear power reduction, pit lane
speed limiter. All this can be programmed using a handheld Aprilia
Racing Palm system and adjusted on-the-fly with bar-mounted switches.
There’s also an onboard data acquisition system and a special set of
instruments able to show individual lap times and information related to
the above systems.

Rearsets, single-seat tail-unit, carbon fiber fairings, carbon/Kevlar
engine protectors, racing clip-ons and a few other bits and pieces.

Notably absent from this list of upgrades is the controversial
gear-driven camshaft, the SBK swingarm and the underseat fuel tank. Nor
is there any mention of how the Biaggi rep makes its extra power. Since
the 48mm throttle bodies and engine internals remain identical to other
RSV4s, we’re going to assume that extra power comes via the open exhaust
and the re-mapped ECU. A similar explanation can be found for the 4kg weight reduction (now 175kg without battery or fuel), ditching the stock exhaust and swapping the stock bodywork for lighter items likely accounts for this.

The track-only Biaggi replica will retail for €50,000 ($64,319). That’s a
€30,000 premium over the RSV4 Factory. While the upgrades undoubtedly
price out at a similar level, they’ll be of limited use to the average
track day rider. The only people we see benefiting from upgrades like
the fancy electronics or quickly-removable gearbox are small race teams,
but without modified engine internals that €30,000 premium is going to
be hard to swallow when more power can likely be achieved for less
investment. Still, we’d really like to have that top yoke on one of our

    Not realy my kind of bike, but I love the ‘higher’ than normal primary. The angle just makes the whole swingarme area look cool.

    What is this ‘top yoke’ you speak of?

      That might be the Englander in me trying to get out. “Top triple clamp” work better?

    Too bad its not coming to the states. I really would have enjoyed pretending to be pretending to be Rossi. Oh, what a life Biaggi has.

      @ the_doctor: That was funny.

      @ Aprilia: How about selling the already-awesome RSV4 with just the beautiful Alitalia graphics (sans number)?

    Anyone wanna buy a kidney?

    what’s that tube coming out of the left of the gas tank and going to the reservoir inside of the front cowl where the headlight would be located?

  • Peter

    and that triple clamp is really beautiful. i’ve never seen anything like it.

    Awesome bike but for $64K I want the swingarm and the gear driven cams. Ducati did a MotoGP rep for $72K and as far as I know (which isn’t much) it had all the goods included. And yes, that triple clamp is a standout!

    The top triple clamp moves the flex to a different area, proper racing forks are a lot stiffer, and the flex is needed for front end feel. The moto gp yamahas have been using similar designs for about 5 years now.
    The tube coming out of the fuel tank is a breather hose.
