PARIS Hilton has tapped into the two biggest passions of Spanish men: women and bikes.

The California socialite chose Madrid as the place to launch her new motorcycle racing team SuperMartxe VIP.

And to celebrate the event, she danced till down in megaclub Fabrik, just like she did in Ibiza this summer.

The invite-only party hosted 5,000 revellers, many dressed in pink, white or blue – the colours of her new team.

SuperMartxe will compete in the 2011 MotoGP World Championship in the 125cc category.

And Paris’ contract with Barcelona-based constructors By Queroseno Racing (BQR) obliges her to attend every race for the next five years.

Hopefully she won’t get tired of socializing by then.
