Stephen Sword will make his competitive debut on-board the Relentless Suzuki by TAS RM-Z250 this weekend, as the team's new signing takes part in the opening round of the British Supercross Championship, at Sheffield Arena on Saturday evening.Sword, who agreed terms with the official Suzuki team earlier this month, will ride the RM-Z250 for the first time in competition and feels optimistic about his chances following recent tests on the bike in the run-up to the event.Stephen Sword: "I go into the opening round of the Supercross Championship feeling better prepared and more optimistic than ever. Recent tests on the RM-Z250 have been really encouraging and with such a good feeling on the bike I'm hopeful of ending the opening round in a commanding position that should help us challenge for the title."Team manager, Adam Lyons, added, "Stephen's already really clicked with the RM-Z250 and with his vast experience and professional approach to every element of his racing we're all feeling pumped and ready to fight for another championship. Crucially, this championship also gives Stephen invaluable time on the bike in a competitive arena, before we start the outdoor racing next year."2011 Team Partners include: Suzuki GB PLC, Relentless, Beacon, Alpinestars, Pirelli, Talon, Rental, Polisport, Regina, Leo Vince Exhaust, Leo Vince Carbon, Pipercross, Red Torpedo, Worx, Hel, SPS, Samco, Moto Graphix, Motul, Factoryfoam
