Italian Fire On A Trellis
MV Agusta built the F3 675 around a 675 cc inline-three with a counter-rotating crank, and almost everything else about the bike follows from that decision. The 126 hp peak arrives at 14,400 rpm and the 52 lb-ft at 10,600, so this is a machine that wants revs and pays back a rider who uses them. A steel trellis frame, fully adjustable suspension at both ends, and a ride-by-wire package with ABS, traction control, ride modes and an up-shift quickshifter make up the hardware. At 423 lb wet it sits among the small, sharp end of the supersport class, and it looks like nothing else in the parking lot.
This is a motorcycle drawn by people who cared more about intensity than about sanding the edges off. The riding position is committed, the 31.7 in seat is narrow, and the payoff is a chassis that stays honest the harder you lean on it. It suits a rider who already has the skill and wants the drama that comes with it. It is not for anyone who buys motorcycles on service intervals and running costs. Ownership asks for attention: a valve spring can break and drop a valve into the cylinder, the starter sprag clutch can fail, and the rear brake master cylinder can lose pressure or leak.

Safety
Hit the starter and the triple clears its throat with a hard, metallic rasp that sits somewhere between a twin and a four, and it only gets better the harder you work it. You sit in a tight, wrists-loaded crouch with your knees folded high against a narrow tank. At town speed there's a fine buzz through the bars and pegs, and the finish is right there in your eyeline: the welds, the switch housings, the way the tail sits over the rear wheel. Pick up the pace and the bike seems to shrink around you. Feedback comes up through the front tire in a steady stream, and lean clearance is so generous that on the road you run out of nerve or tire long before anything touches down. Two hours in, your wrists and neck know exactly what you signed up for.
This part isn't my own seat time. It's what accumulates when you spend enough time around riders: pit-lane talk, club nights, parking-lot conversations after a ride, and the notes that land in my inbox. On the F3 675 owners agree with each other, and they agree in two directions at once.
The triple dominates. Owners describe a motor that keeps climbing to the top of the rev range, and many took it as the class output leader when it arrived. Right behind that comes how little mass carries all that performance. Agility gets described as track-grade, with composure that holds as the speed rises. Nearly every owner mentions the styling. The electronics get credit as well, rated sophisticated for their day.
Reliability leads the complaints and it isn't close. Riders raise the starter sprag clutch, rear brake trouble, and electrical faults that come and go, and they are blunt that you want a specialist dealer and patience. Fuelling is the next steady theme: snatchy down low on early bikes, with flat spots that make town work tiring. On imperfect pavement, the race-stiff suspension gets called out for kicking.
Valve spring failure causing dropped valve
A valve spring can break, allowing the valve to drop into the cylinder and cause catastrophic engine damage.
Premature sprag clutch failure
The starter sprag clutch can fail, causing grinding noises and difficulty starting; often requires replacement.
Rear brake master cylinder failure
The rear brake master cylinder can lose pressure or leak fluid, reducing braking effectiveness; replaced under warranty on some models.

Forget spec-sheet bragging. Here's who the F3 675 is actually built for.
Angeles Crest is exactly where this bike makes sense: light, precise, and loud enough to turn a Sunday morning into an event. Budget for the upkeep it will eventually ask of you.
Made for Angeles Crest Highway · Coronado Trail / US 191 · Highway 1 / Big Sur
It gives you what a track session needs: fully adjustable suspension, lean clearance you cannot use up, and clear feedback. With no slipper clutch, your downshifts have to be tidy.
Made for Barber Motorsports Park · WeatherTech Raceway Laguna Seca · Circuit of the Americas
The Dragon and Cherohala reward a small, sharp bike, and this is one of the sharpest. It is a skill machine, not a comfortable one, so plan the drive in and ride it in short, hard stints.
Made for Back of the Dragon · Blue Ridge Parkway · Cherohala Skyway
If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.
Any price note compares both bikes at the same age — the youngest age both have on the used market — against this MV Agusta F3 675. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
