Not content with claiming his third world championship in as many years and smashing Mick Doohan's 17-year old record of race wins in a single MotoGP season, Marc Marquez is preparing to take on a selection of the world's finest dirt trackers at the Superprestigio event in Barcelona.

Following on from the successful inaugural event last January, the second running of the Superprestigio takes place on Saturday and boasts a line-up befitting of its venue and organiser. Set in the classy Palau San Jordi, metres from the old grand prix road circuit in the Montju?c hill overlooking the Catalan capital, Marquez has invited an all-star cast to lay siege to the 200-metre circuit.

Usually the scene of music concerts and national basketball events, the arena has been transformed into a dirt-lined oval for the season-ending event. On Friday it welcomes six road racing world champions in the 'Superprestigio' class and a further four in the 'Open' category for testing before the practice, qualifying and racing heats take place on Saturday.

Continuing the proud Catalan tradition of hosting world class dirt track events which pit grand prix stars against American dirt trackers, the 2014 showcase will see a repeat of the January vintage, in which Marquez was overcome by American Grand National flat track champion Brad Baker in the final for the maiden Superprestigio title (pictured).

Baker and Marquez's job will be a notch more challenging this time around after the announcement that three-time World Superbike champion Troy Bayliss had entered the event. Now 45-years old, Bayliss has been taking dirt track seriously since his world championship retirement in 2008 and is the current holder of Australia's 250/400cc dirt track titles.

The two remaining 2014 grand prix world champions, Tito Rabat and Marc's younger brother Alex, are also entered alongside MotoGP 'Factory' riders Scott Redding and Bradley Smith. Add in ex-world champions Toni Elias and Julian Simon, plus grand prix winners Mika Kallio, Johann Zarco, Jordi Torres and Jonas Folger and the 'Superprestigio' category alone enjoys a superstar-studded feel.

No less than 112 grand prix victories and eleven world championships are shared across the class.

Baker meanwhile will have to contend with current American Grand National flat track champion Jared Mees and 2012 All-Star Pro champion Shayna Texter in the 'Open' class. Fresh from claiming his second national title in October, Mees will have American expectations resting on his shoulders as he aims to uphold the USA's proud dirt track tradition in his first European race.

Great Britain is well represented in the 'Open' category too, with Guy Martin, 15 times a podium finisher at the Isle of Man TT, the highest profile participant. As was the case in 2013, British dirt track specialists Tim and Tom Neave are among the 48 entries. Ex-World Superbike runner and former British Supermoto champion Christian Iddon will line up in the 'Superprestigio' class.

The 'Open' class also boasts four world champions of different racing disciplines. Four-time World Enduro champion Ivan Cervantes will compete alongside Taddy Blazusiak [five time Superenduro world champion], Thomas Chareyre [three time Supermoto world champion] and Joonas Kylmakorpi [three time FIM Long Track Champion].

Riders got a feel for their machines on Thursday afternoon at the pre-event shakedown at the Rufea dirt track, 100 miles west of Barcelona. An hour-long test session gets underway on Friday evening before free practice starts at 11.00 on Saturday.

The Superprestigio and Open heats then begin at 18.00 before the four best riders from each class subsequently meet for a twelve-lap dash in the 'Superfinal' event.

If January's event is anything to go by Saturday should serve up another scintillating battle, befitting of its location and entry that will go some way to showing whether Americans can still claim to be the masters of dirt track.
