what is rieju? or this firm associate with aprilia please more informacion and plese information about rieju rs1

Answer 1

Made in Spain, most of their engines are produced by Minarelli although some of the smaller sport bike models have engines built by Yamaha.  For the scooter line, they've switched to engines from a Chinese company called Sonik.

The y4t motor used in the RS is from Yamaha, not Aprilia.
