Movistar Yamaha rider Jorge Lorenzo scored his fourth consecutive MotoGP win at the Gran Premi Monster Energy de Catalunya at Barcelona. He finished just over one second ahead of teammate and MotoGP points leader Valentino Rossi, with fellow Spanish rider Dani Pedrosa rounding out the podium.

Reigning World Champion Marc Marquez had another disappointing race as he made an unforced error while trying to pass Lorenzo for the lead and crashed at Turn 10. It was a race of attrition as many riders fell out of the race due to on-track incidents.

Aleix Espargaro and teammate Maverick Vinales put Team Suzuki Ecstar on the first two spots on the grid, scoring the first Suzuki pole since Chris Vermeulen at the 2007 Dutch TT and the first Suzuki 1-2 start since Kevin Schwantz and Alex Barros did the deed in 1993. The partisan Catalan crowd was thrilled that four Spaniards took the top four starting spots: Espargaro, Vinales, Jorge Lorenzo and Marc Marquez.

Yonny Hernandez and Cal Crutchlow both crashed on the first lap, the first of 9 DNFs in the race. Repsol Honda rider and World Champion Marc Marquez suffered his third unforced error of the 2015 season when he attempted to challenge Lorenzo for the race lead and crashed in Turn 10. Another World Championship in 2015 seems to be in doubt for Marquez.

Jorge Lorenzo took the lead on the first lap and never relinquished it, with little pressure from behind. Yamaha teammate Valentino Rossi was able to rebound from fifth place on the opening lap to score a second place. Dani Pedrosa hung on and stood third on the podium for the first time since his return from arm surgery.

Ducati rider Andrea Dovizioso crashed out from third place, followed shortly by Pol Espargaro's incident while running seventh. Brother and pole winner Aleix Espargaro was not able to finish as he crashed out late in the race from fourth position. 

Valentino Rossi maintains a slim one point lead in the World Championship over teammate Jorge Lorenzo heading into the next race in two weeks at the Dutch TT in Assen.

In the Moto 2 race, Ajo Motorsports rider Johann Zarco won a thriller after surviving an incident in Turn 1. He took the lead at Turn 4 on the final lap and was able to hold off Tito Rabat for his second win of the season. Zarco holds a commanding 40 point lead in the championship fight.

Moto 3 championship leader Danny Kent won his fourth race of the season, the first British rider to do this since Barry Sheene in 1977. Kent finished 0.035s ahead of Enea Bastianini. The Leopard Racing rider extends his points lead to 51 points over second place.

The MotoGP World Championship will take to the track next in two weeks' time in Assen.
