Marc Marquez took his fo💯urth successive 125cc grand prix victory - and the world championship lead -𒁏 in dominant style, in front of his home Spanish fans at Catalunya on Sunday.

The Red Bull Ajo Derbi rider, unbeaten since his first ever grand prix victo🙈ry at Mugello, led comfortably from start to finish🔥, taking the chequered flag with a 4.638sec advantage over nearest rival Bradley Smith.

Marquez is now the youngest ever rider to claim four successജive grand prix wins, taking the record🥂 from a certain Valentino Rossi.

The 17-year-old, who has been moving steadily up the championship order since crashing at round two at Jerez, now leads the🐼 125cc championship by one point from counཧtryman Pol Espargaro.

The fight for second place went down to the line with Nico Terol, Espargaro an🐽d S🤪mith locked in battle for the entire race.

The final ♔lap saw Spaniards Terol and Espargaro𒁏 both pass Smith into turn one, with Espargaro then moving into second.

Smith muscled back past his A𒆙spar Aprilia team-mate Terol and the trio fanned out across the track heading into the left hander at the end of the back straight, where Smith regained the runner-up spot.

But Terol, who began the race with a three point title lead ov🦩er Espargaro, came close to hitting the back of Smith under braking, then highs⛦ided out as he applied the power.

Terol leaves Catalunya third in the championship, 14 points from Marquez, 𝐆with Smith 38 points from the top in fourth.
