presentation of the Aventura 125 2025

The new 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.
