Motorcycle specifications Rieju Aventura 125 2026 The small horizon
presentation of the Aventura 125 2026
The Aventura 125 enhances Rieju's range of lightweight trail bikes. It retains the rugged, all-round character that has made it a benchmark in its class, while now incorporating enhanced safety features, boosting performance and reliability both on and off-road.
Compared to the previous model, there are no design or chassis changes. The main new features include traction control (TCS) and an ABS braking system.
The engine is now super-square ribbed. The 15hp, 4-valve, liquid-cooled, electronically-injected, single-cylinder engine is more efficient and fuel-efficient - perfect for everyday use or weekend getaways. Its double-beam steel frame, combined with an upside-down front fork, promises a solid, stable structure on all types of terrain. Faithful to the trail spirit, it also features practical and functional equipment such as a TFT screen, an engine mount and a large rear rack for a top case or luggage.
Designed for those looking for an affordable motorcycle with a true spirit of adventure, the new Aventura 125 is a good companion for those just starting out in the world of trail riding.

Bikers' reviews Leave a review - 2 reviews
A few points to note, however: rust on the exhaust and the chain, which is of questionable quality.
Otherwise, it pulls well, the engine has plenty of torque and can maintain 65-70 mph on the highway.
It's reliable and takes me to work every day for less than 3 liters per 100 km. Rating : 4/5 Respond to Catalan
