A foolhardy motorcycle gang member set himself on fire before hurling himself off a platform and into the sea as part of a bizarre social media stunt, wild video shows. 

The 20-year-old prankster – who is thought to be part of the unruly “little horse” gang – doused himself in fuel and lit his black hoodie before jumping off a wall into the sea at the Port of Valencia, Spanish outlet Las Provincias reported last Wednesday.

The bizarre stunt, which has recently gone viral on social media, took place in front of the Ripoll refueling station.

Experts have warned wannabe-pranksters — stressing the stunt could be deadly and could cause third-degree burns.

But it was glorified by an influencer who promoted a biker meet-up that took place in Valencia last Friday, the outlet reported.

And the youth who participated in the stunt is said to be a prominent member of motorcyclist posse La Banda del Caballito, The Sun reported.

Gang members are known for riding recklessly on motorcycles – despite some having no licenses.

Video surfacing online shows them weaving in the road and performing wheelies.

They arrange meet-ups secretly, posing a headache to local law enforcement. 

Earlier this month, a 12-year-old who was part of a group of 25 motorcyclists was caught driving one of the bikes, Telecinco reported.

The bikers were seen hurtling down the A-7 highway in Torrente before they were intercepted by a squad of cops.

The reckless youths ignored cops’ orders – and one yob even caused damage to an officer’s car.

Six motorcyclists were arrested in total – and some were under the influence of drugs, police said.

Cops have warned that the bikers could face up to two years in prison.
