Bornok Mangosong delivered a commanding performance at Rounds 3 and 4 of the 2026 RFS Dirt District Motocross Pilipinas Onslaught National Series sanctioned by NAMSSA, held last May 23–24 at RFS Dirt District in Vermosa, Cavite.

Promoted by RFS – Ride For Solidarity headed by Angelo Ambil, the event once again showcased some of the country’s top motocross talents in one of the most competitive weekends of the season.

Mangosong swept victories in both the MX2 and MX1 Premiere Classes, showcasing his versatility and dominance across two highly competitive categories.

Competing aboard the Fantic XXF250 in the MX2 division, Mangosong displayed impressive consistency and speed throughout the weekend. He then carried that momentum into the premier MX1 class aboard the Ducati Desmo450 MX distributed by Ducati Philippines Access Plus.

Providing the toughest challenge against Mangosong was Terrence Napat of Team MBR. During the MX1 battle in Round 3, Napat attempted several block passes in an intense fight for the lead before suffering a crash in the berm. Despite the incident, Napat managed to recover and still finish in an impressive P2 performance.

Originally from Asingan, Pangasinan and now residing in Puntalinao, Davao, Mangosong’s latest triumph adds to an already legendary career that spans more than a decade in Philippine motocross. With 17 Premiere Class titles to his name, he continues to solidify his legacy as one of the most accomplished riders in the history of the sport.

With the double sweep in Vermosa, Mangosong now takes full control of the 2026 championship standings as he continues his pursuit of yet another national title. 💪🏆
