Trials Bike Chase Scene in the new Bourne Ultimatum movie

  There is a chase scene on the new Bourne Ultimatum movie where Jason Bourne (Matt Damon) "hot wires" a Trails bike, in the City of Madrid, and goes after the bad guy, through the narrow streets and sidewalks, taking short cuts over walls and fences, etc.    I'm not sure who did the stunt riding, but he looked a lot like David Chaves from the back (much thinner than Matt Damon).  Its an exciting scene in a fast paced movie.  The movie is pretty much a 2 hour chase/fight scene, filmed from a "shakey hand held camera" point-of-view.

I need a helmet like that.  Can you get them from RYP?

How do I get MY trials bike to have that "high reving 4 cylinder sport bike" sound?
