presentation of the 125 Black / British Seven 2025

Since its beginnings, Mash has chosen the retro arena to carve out a place for itself in the motorcycle galaxy. The Seventy launched the brand's success, proving that it was also the right choice with its vintage-style 125s. The range underwent a plethora of variations until the big clean-up in 2021. One of the few survivors is the Seven. BLACK Seven! Or BRITISH Seven, depending on how you look at it.

It's a very clever trick. Depending on whether its color is green or black, the machine changes its first name. It's envy only smiles, and is more interested in the search for more rebellious souls, with an undisguised perfume of the suburbs of England.

the little English flag on the airbox cover marks his inclinations. The chic elements continue the illusion. Spoked rims, tapered pot, a few touches of chrome, a metal front mudguard and a long, flared seat; all under a layer of styling that's a little more aggressive than the Seventy. And, coincidentally, in the same vein as a certain Orcal Astor. The Mash has since been overtaken by other rivals, but it's still going strong.

no inverted forks for the Seven, but plenty of character. With an all-black package: headlight cladding, fork sleeves, protective gaiters, brake calipers, wheel rims, fork crown - only the tank and center panels can vary and set the tone; English or Sirius.
This Mash seems to want to emerge from the London fog, with its British face, French accent and Chinese origins. The engine has other concerns. It's time to move up to Euro5, and make its mark even further.

Mash 125 Black / British Seven the other 125 roadster in the range, the Seventy, wanted to keep its old engine, which the Seven also carried... Until now. Those days are over, as the new block testifies. Mash changed its supplier to Korea's Hyosung. The improvements are unmistakable: much more efficient liquid cooling, 4 valves, a 6-speed gearbox (instead of 5), less polluting emissions and a more than noticeable gain in power. The Seventy 's cousin announces 11 horsepower; the Seven laughs with 15. Comfort and driving pleasure are on a different level.
On the other hand, a modern engine is heavier and more expensive... The bike climbs to 137 kilos in running order.

the Black Seven made do with combined braking. As it evolves on the engine side, it also gets ABS to supervise the 2-piston front caliper biting its 300 mm disc and the 220 mm rear disc.
A new, redesigned speedometer unit sits above the headlight. Still featuring a double dial with hands, it looks much more elegant and polished. It also gains a small digital window and a gear indicator.

The Seven retains its little refinements. As evidenced by the center stand, removable stainless steel pot, LED taillight, Fat Bar handlebars and Monza-style cap.
Surely the most mature 125 in the range. Enough to keep the public coming back without tipping over into pretentiousness.

Very satisfied
French JCF32 Model 2024
1st motorcycle after recently passing A1, very happy at this stage, running-in still in progress but already a lot of pleasure for my use (work, riding on main road) great look that leaves no one indifferent when I ride it outside Rating : 5/5
Avis british seven
French DLmoto Model 2022
I've had this bike for 2 months and 1500 kms on it. The engine is good for a 125 and the look is great
¨As for quality, it's nothing like the mash bikes of years past
overall build quality is good without being exceptional

i did have one problem with the water pump, however, due to a forgotten engine breather cap during assembly
but everything was taken care of under warranty by mash without a hitch
1.90 seems to me to be the maximum size for this kind of bike, given the shape of the tank
Rating : 5/5
Avis ?
French Sevy Model 2022
Hello, are there any reviews of this Mash? I've heard that Mash has made great strides in the quality of their bikes and I'm very interested in the look of this, which I think is magnificent. Any thoughts on the new 15 hp engine? Is the seat high enough for someone 1m90 tall? Rating : 5/5
