New mid-size model with the outstanding riding performance of the RG series

The RG80E is a European street bike equipped with an 80 cm³ 2-stroke 1-cylinder power reed valve engine that combines an impressive maximum horsepower of 10 PS with easy-to-handle flat torque characteristics. This engine features an aluminum cylinder and cylinder head for improved heat dissipation, enabling ideal performance for long runs and other tough riding conditions.
