presentation of the Stealth 125 2025
Fantic brings a motorcycle to the 125 market that's sure to turn heads. With its looks, chassis and performance, the Stealth 125 follows in the footsteps of the 125s that made young people dream, such as the Cagiva Mito and Aprilia RS.
So should you shell out the 5,490 euros for this little beast?
Competition chassis
When a 125 wears a feathered head on a cheap chassis, it's a real eye-catcher! Here, Fantic offers a chassis that's quite exceptional in its class. The frame's front end and seat support are made of steel trellis. These two structures are anchored on beautiful forged aluminum plates. The extension of these plates to the reinforced swingarm, also in aluminum, is no less impressive. The design of this chassis is reminiscent of Bimota craftsmanship, for example.
The front fork has a sporty look, with its gold forks and a 41 mm diameter. The rear shock is adjustable for spring preload. Braking is strong, with a 320 mm ByBre front disc with radial clamp and a 230 mm rear disc. ABS is standard, with dual independent channels and deactivation at the rear. An optional reactive cornering ABS is available, as on superbikes.

The result is impressive, with a dry weight of just 129 kg! A real featherweight that should turn the Stealth into a toy that's easy to swing from corner to corner. Particularly given the high saddle height (810 mm), the Stealth is ideal for cornering. With all its fluids (oil, 12.5 liters of petrol in the tank, etc.), the bike should weigh in at around 145 kg in running order.
A point often neglected in original equipment, this Stealth 125 comes with some nice socks. Pirelli Diablo Rosso IV tires measure 150 mm at the rear and 110 mm at the front. The big rear tire provides looks and grip, but is likely to eat up some horsepower ..
You've got the look you need!
The wrapping of this fiery chassis is rather seductive. Fantic has succeeded in giving its machine a strong identity. The small, streamlined optic at the front features LED lights, making the bike a true sports bike. The shift from front to rear is very well executed. The side view highlights the designers' work, with scoops linking the front to the tank and then to the seat shell. The little hoof is designed to cover the lower part of the bike, which is often overlooked in this market.
The high-mounted exhaust is perfectly in place and doesn't spoil the picture - quite the opposite, in fact. All this evokes memories of a Bimota Delirio that had evolved with the times, and the Stealth 125's styling is a success.

As a small concession to comfort, the bike is equipped with adjustable brake and clutch levers. Foot controls can also be adjusted to 2 positions.
The instrument panel features a 5-inch TFT color display. It displays all the necessary information: driving modes, gear engaged, fuel gauge, etc., etc. ..
Engine: Minarelli's best
For the 125's boiler, Fantic has enlisted the services of a well-known engine manufacturer: Minarelli. A late specialist in 2-stroke distillers since the '50s, Minarelli knows how to make small, cheerful engines. This 125 cm3 4-stroke develops 15 horsepower. We don't yet know its maximum rpm or torque values. However, Fantic specifies that the bike is Euro 5+ approved. This little engine comes with a number of features that, once again, recall the higher categories: anti-dribble clutch and Variable Valve Actuation (VVA) system for variable intake valve timing, a bit like BMW's Shiftcam on large-displacement engines.
To exploit the engine, the budding racer in you will benefit from two engine modes: Street and Sport. The gearbox has 6 speeds.

Also a toy for grown-ups
You'll need to have put money aside from an early age to buy the Stealth 125, which retails at 5,490 euros, or to be very nice to your parents to be offered the little buggy ... which Dad, if he's a biker, might well steal to fetch the bread on Sundays, just to play the fool on his handlebars! Because with these toys, fun is guaranteed at any age.
