Ruben was born in Barcelona on the 18th February 1978.
His father, who had competed in amateur motorcycle “mountain” races, was probably Ruben’s biggest influence and had Ruben on a 25cc Montesa by the time he was 5 years old! From that day he taught Ruben how to ride and encouraged him to perfect his riding by practicing endlessly on dirt bikes. At the age of 8 he progressed to a KX60 and then by 11 a KX80.

At the age of 14 he was ready for a bigger dirt bike but his father had a different idea: “Let's go road racing.” With his father’s mechanical knowledge and the help of friends, Ruben started his road racing career at 14 years old in the 125 Championship of Catalonia. Hungry for racing experience, he continued into 1993, taking part in the Solo Moto 125 Criterium and winning the 80cc Supermotard Championship of Catalonia. Ruben was ready for big bike action.
