Coba jelasin Kejuaraan Dunia Superbike dari Jonathan Rea dong

For 2009, Rea rode for the Hannspree Ten Kate Honda team in World Superbikes. He made the switch before the end of 2008, meaning that he made his WSBK debut in the final 2008 round at Portimão. His first podium came in the second race at round six at Kyalami. Another third place followed in the very next round at Miller Motorsport Park, before his first WSBK win came at Misano, after a frantic battle with the Ducati duo of Noriyuki Haga and Michel Fabrizio. This followed a chaotic first race that day; his bike failed on the dummy grid, he received a ride-through penalty for being given a lift back to the pits by Kiyonari on the warm-up lap, and when he switched to a wet set-up bike he – like teammate Carlos Checa – had trouble getting the second bike fired up.

He added a further win in Germany to finish fifth overall and second best rookie behind top rookie, Ben Spies, who won the World Superbike championship that year. He remained with Ten Kate for 2010, and scored a double victory at the team's home round at Assen, however this was followed by two crashes at Monza. A further crash in Superpole at Miller Motorsport Park injured his neck and shoulder, though he still raced the next day, scoring a 14th and an eighth. He scored only seven points at Misano, as he fell behind Carlos Checa in the battle for third place in the championship standings.

For the 2011 season, Rea stayed with the Ten Kate Racing family as its Honda-supported World Superbike team received backing from global lubricants manufacturer, Castrol, reviving the famous Castrol Honda name that saw World Superbike championship victories with John Kocinski in 1997 and Colin Edwards in 2000 and 2002.

After spending his entire career riding Honda machinery, Rea joined Kawasaki Racing Team as Tom Sykes' new teammate for the 2015 season. Rea dominated the season and won his maiden World Superbike title, with 14 wins.

Untuk musim 2016, Rea tetap bersama Kawasaki.

Rea retained the title in 2016, 2017 and 2018, becoming the first man ever to win four successive superbike world championships. On 9 June 2018, Rea won the first race at Brno to take his 60th career win and surpass the record of Carl Fogarty.
