Anthony Joshua celebrated winning the Commonwealth heavyweight title in style by adding a ‘new toy’ to his collection.

The undefeated 25-year-old, who won his bout against Scotland’s Gary Cornish with a first-round total knockout last weekend, purchased a lime green Kawasaki KX250F dirt-bike to expand his already impressive selection of off-road vehicles.

The former Olympic champion has recorded 14 knockout victories in 14 professional fights so far, and floored Cornish with his first right hand during their match at the O2 Arena.

Based on his performance against Cornish, Joshua’s inexorable rise through the world of boxing shows little sign of letting up.

Cornish was beaten within 97 seconds in Greenwich, which means that Joshua has only needed a total of 26 rounds to see off all 14 of his opponents. Not one of them has lasted beyond the third-round with him.

Joshua’s next fight will be against Dillian Whyte, who did beat him as an amateur and with whom there is plenty of lingering bad blood.

Ahead of their bout on December 12, tickets for which sold out in six hours on Wednesday, Joshua said: ‘My ambitions are higher than Dillian Whyte.

‘He wants to push my buttons but I am going to deal with that boy… I want to beat him and continue down the yellow brick road.’

Joshua has won all 14 of his professional fights by knockout and is yet to be taken past round three
