The 2021 MV Agusta F3 800: Moto2 Technology, Street Legal Supersport

The 2021 F3 800, much like its little brother the F3 675, is where the pure heart of modern MV Agusta lives. The company, after all, is dedicated to the purest interpretation of the Italian desire for form following function, of which the F series bikes are all dedicated to speed.

The F3 800 is a half-generation revamp of the F series, as in 2021, the bike has adopted some lessons learned from Italian manufacturer’s Moto2 GP 2020 season. Principle among these is the world’s first inline-three supersport engine with a counter-rotating crankshaft, which is pure MotoGP level technology, especially at the 800cc sizing which usually uses V-4s or inline-fours.

The 798cc inline-three is finely tuned, producing 148 HP and 65 lb-ft of torque. With the latest control system included, with an aggressive preset, that engine will rev from idle to the redline in the blink of an eye, and threaten to tear your shoulders out of their sockets. The acceleration is that fierce, the torque that instant even down low.

Other major technical advances incorporated into the F3 800 are the newest versions of both the MVICS control system and the MV EAS 2.1 electronically assisted shifter. A full cast aluminum alloy swingarm provides excellent rigidity while being lightweight. The frame of the bike is full alloy steel, with multiple other metals mixed in for torsional strength while reducing the bike’s weight over using a full traditional steel frame.

The 2021 MV Agusta F3 800 starts at approximately $21,170 USD / $26,870 CAD, as it is listed in Euros (€17,490).

2021 MV Agusta F3 800 Features

Advanced electronics

The F3 800 features the latest evolution of the MVICS system with multi-map Full Ride by Wire, 8-level traction control and EAS 2.0 up down electronic gearbox mated to a hydraulic slipper clutch. The electronic injection system has two injectors per cylinder with record 50 mm diameter throttle bodies.

LONGER STROKE

Bore on the F3 800 is the same 79.0 mm, but the stroke increases from 45,9 mm (effective cubic capacity of 675cc) to 54,3 mm (effective cubic capacity of 798 cc), with the rev limiter intervening at 13.500 rpm. Higher-flow fuel injectors compared to the F3 675 ensure additional power, whilst it features the same counter-rotating crankshaft.

Safety

When all you have to think about is riding, fun and pleasure are at their top, especially since safety is ensured by the two-channel Bosch 9 PLUS ABS system with Race Mode. With Rear Wheel Lift-up Mitigation, the system controls the pressure applied on the front brake to avoid involuntary rear wheel lift-up.
