ANTHONY JOSHUA showed he can be a speed machine both in and out of the ring as he ripped round a mud-track on a dirtbike.

The British superstar uploaded footage of himself tearing up the circuit during a little down time ahead of his fight with Oleksandr Usyk.

Joshua, 31, captioned the post: “Dirty shred.” And the clip had ‘All the Love’ by The Lox playing underneath.

The video showed Joshua kick-starting a machine before zooming out of frame.

On-board cameras then provided shots of the heavyweight champ skidding round mud-covered corners.

A laughing Joshua was clean as a whistle dressed in his black protective gear before the session.

But he gradually got muddier and muddier as he whipped round the track.

With mud flying everywhere, at one stage Joshua took a tumble.

He fell to his left as the bike skidded from under him, although he was quickly back on his feet.

Joshua looked like he was having the time of his life and the post now has more than 46,000 likes

‘NEVER AVOIDED A CHALLENGE’

The golden boy of British boxing is fighting Usyk at Tottenham’s stadium on September 25.

With boxing still reeling from AJ vs Tyson Fury collapsing, the WBA, IBF and WBO king has managed to lift the spirits with a mandatory defence against the Ukraine icon.

Joshua won Olympic super-heavyweight gold at London 2012 the day after Usyk, now 34, won the same medal in the heavyweight division.

Usyk went on to rule the 14st 4lbs cruiserweight division as undisputed champion and has now enjoyed two warm-up fights in the blue-riband ranks.

Now the WBO has ordered 24-1 AJ to face the undefeated southpaw.

And recent footage of Usyk in training showed Joshua is not the only speed demon after his dirtbike antics.

Speaking ahead of the fight, Joshua said: “We are two Olympic gold medallists who have fought our way to the top and never avoided challenges.

“The stadium is exceptional, the atmosphere will be electric.

“I’m honoured to be the first person to fight in such an awe inspiring venue.

“The stage is set and I am ready to handle business.”

Promoter Eddie Hearn believes those fans attending Spurs’ ground will NOT need a vaccine passport.
