PROGASI Flex 250
PROGASI Flex 250
PROGASI Flex 250 is a lightweight naked street motorcycle for riders who refuse to let the road dictate how they ride. After all, Flex stands for flexibility, adaptability, and versatility. One moment you're confidently weaving through busy city traffic on your morning commute, and the next you're carving through a series of sweeping bends on your favorite country road. The Flex feels equally at home in both environments. As PROGASI's first purpose-built street motorcycle, the Flex was designed from the ground up exclusively for pavement. Drawing on years of experience developing enduro motorcycles, PROGASI engineers carefully analyzed rider feedback from previous models and refined every aspect of the bike. The result is a modern urban machine that combines effortless handling, responsive performance, and the reliability required for everyday riding.
Powerful engine for the urban lifestyle
At the heart of the PROGASI Flex 250 is the new JYZ250 four-stroke engine with a displacement of 250 cc, producing 25 hp. Paired with a well-balanced six-speed transmission, it delivers brisk acceleration from traffic lights, responsive mid-range performance, and relaxed cruising on open highways. With a top speed of 125 km/h, the Flex easily keeps pace with highway traffic while providing confident overtaking performance. The engine's smooth and flexible power delivery makes it equally enjoyable for new riders and experienced motorcyclists alike. The air-and-oil cooling system, equipped with a highly efficient oil cooler, maintains optimal operating temperatures even in heavy city traffic and hot weather. By keeping the engine oil cooler, it helps preserve its lubricating properties for longer, reducing engine wear and ensuring dependable performance during intensive daily use.
17-inch street wheels
The PROGASI Flex 250 comes equipped with lightweight 17-inch cast alloy wheels featuring stylish five Y-shaped spokes and a new set of street-oriented tires designed specifically for confident riding on asphalt. These tires provide excellent grip even at significant lean angles, allowing riders to corner with confidence and fully exploit the capabilities of the chassis. A well-developed water evacuation tread efficiently disperses water from the contact patch, maintaining stability and enhancing safety when riding in wet conditions.
Bold urban styling
The front end of the PROGASI Flex 250 features a sharp, modern design that perfectly reflects its urban character. The full LED headlight, highlighted by its distinctive diamond-shaped daytime running light signature, gives the motorcycle an instantly recognizable appearance while delivering bright, evenly distributed illumination after dark. LED lighting also improves visibility while minimizing power consumption.
Sport-tuned suspension
Handling precision comes from a modern upside-down (USD) telescopic front fork, specially tuned for spirited street riding. It absorbs imperfections in urban pavement with ease while remaining firm enough to provide excellent control during aggressive cornering. Whether accelerating hard or braking aggressively, the suspension remains composed and stable. In corners, it delivers precise feedback from the road, and when combined with the motorcycle's lightweight chassis, makes the Flex exceptionally agile, responsive, and predictable.
Flexibility you can feel on every ride
The PROGASI Flex 250 is built for riders who don't want to be limited to a single style of riding. It is equally suited to daily commuting, evening rides through quiet city streets, spirited weekend runs on winding roads, or relaxed weekend escapes. The PROGASI Flex 250 effortlessly adapts to your riding style and your mood. That's the philosophy behind its name—to remain versatile, stay quick, and deliver pure riding enjoyment wherever the road leads.
