Underbone 150

Round 5 of the IDEMITSU FIM Asia Road Racing Championship 2025 happened today at the Sepang International Circuit, Malaysia, witnessed riders battled both the heat and the technical track in the opening two practice sessions for UB150 class. After a fiercely competitive day, it was Indonesia’s Dimas Juli Atmoko of RACETECH SIXTY Racing who emerged as the fastest rider overall. Dimas stamped his authority in Practice 2 with a blistering 2’32.015s, edging ahead of a strong field and setting the benchmark for the weekend. Close on his heels was compatriot Gupita Kresna Wardhana of ZIEAR LFN HP969 MCR RBT 34, who combined consistent pace across both sessions to secure second overall with 2’32.789s. Fahmi Basam of YAMAHA LFN HP969 INDONESIA RACING TEAM claimed third at 2’33.024s, showing solid speed and adaptation to the hot conditions. Rounding out the top five were Ahmad Afif Amran of Pitsbike Superfast JRT Racing Team in fourth at 2’33.571s and Md Akid Aziz, also of Pitsbike Superfast JRT Racing Team, in fifth with the lap time of 2’33.643s. Dimas commented, “During Practice 1 and Practice 2, Alhamdulillah, the results were very positive for my preparation for the Superpole session. My mechanics and team always strive to improve from the previous races. I also feel more motivated after winning the race in Mandalika. For this race, I hope I can reach the podium and score more points. I will continue to work hard for good results.” TOP 5 FASTEST – PRACTICE (COMBINED)

Without a shadow of doubt, the road to stardom for Husni Zainul Fuadzy of ZIEAR LFN HP969 MCR RBT 34 in the Underbone 150cc race category is paved in gold and while he lost his chances of claiming the crown early at Mandalika, his moment to shine may just show up in Round 5 at Sepang International Circuit. What spins the narratives differently though is the story of Fahmi Basam of YAMAHA LFN HP969 INDONESIA RACING TEAM and Dimas Juli Atmoko of RACETECH SIXTY RACING who will take their battle to the next level for the 1st runner spot. After his double-win, Dimas quickly scaled three spots up to the third place, with only a 3-point difference with his closest contender Fahmi who currently graces the second spot. But turning the tables around may not be a completely easy task in the UB150 race category known for its highly competitive battlefield and unpredictability, especially with a rival fully equipped with the capacities needed to maintain his game plan. Over the course of eight races, Fahmi has not only showcased his prowess but has also stepped up onto the podium five times, making him one of the finest contenders to the troop of riders. Dimas on the other hand is not bad himself considering the three podium-finish he obtained to-date however what could be a concerning factor in the upcoming round is his double DNF on Sepang grounds in round 2. Could he overcome the fears of possible shortcomings, keep up to his winning momentum and glide to a celebratory finish at Sepang? Not forgetting the likes of Malaysian teammates, Ahmad Afif Amran and Md Akid Aziz of PITSBIKE SUPERFAST JRT RACING TEAM who are sure to speed up on their familiar grounds. Commenting further, Dimas said, “The win at Mandalika was definitely attributed to the machine condition especially since we have been working hard to fine-tune the setup from the beginning of the season. The difference back then and now, I would say is that, I was too hesitant to take risky moves due to the regulations. For the coming round at Sepang, thankfully, we already have data from the previous race. Maybe back then it was not my lucky day, or maybe, I did not have it in me. But right now, more so with the double-win, I am more confident and I think I can do well enough to take a step up on the podium.” “With a 3-point difference, my motivation level has fired up. I finally stand a chance to be at the top three positions. Of course, racing to the top is not possible at the moment but surely, the top three spots are still open for contention. Racing is not always about skills and speed, especially in the Underbone race category whereby everyone is on par in terms of competency and everyone has a chance to strike the iron while its hot. It also has a lot to do with luck too. I am prepared physically and mentally and I will for sure give my all to hit my target. The only thing I hope for now is that luck will be on my side as well by God’s grace.”

Round 4 of the IDEMITSU FIM Asia Road Racing Championship witnessed yet another thrilling battle in the UB150 category at the Mandalika International Circuit, where Indonesian hero Dimas Juli Atmoko of RACETECH SIXTY Racing stormed to his second win of the weekend in front of a jubilant home crowd. At the start, Ahmad Fazrul Sham of CARDINALS Factory YAMAHA ZYNERGYS Racing Team ARRC got away cleanly but was quickly challenged by Fahmi Basam of YAMAHA LFN HP969 INDONESIA RACING TEAM. The early stages saw constant position changes at every turn, though Dimas remained firmly within the leading group, showing strong consistency. Drama unfolded on Lap 4 when Filipino rider Masato Fernando of KOBY SEC YAMAHA RACING TEAM crashed while April King Mascardo of UMA MMR YAMAHA PHILIPPINE RACING TEAM went down but managed to rejoin the race. Meanwhile, Ahmad Afif Amran of Pitsbike Superfast JRT Racing Team set the fastest lap of the race with a blistering 1’55.016s but was soon overtaken by Adytya Fauzi of JPNW SND FACTORY RACING and Danial Damar of YAMAHA LFN HP969 INDONESIA RACING TEAM, with Dimas quickly clawing his way back to the front. By Lap 7, the lead group shuffled once again, with Fahmi, Dimas, Peerapong Luiboonpeng of ONE FOR ALL, John Emerson of 4S1M EVO YAMAHA Racing Team, and Afif all locked in a tight contest. In the decisive final lap, Mandalika erupted as Dimas made his move, edging out his rivals to cross the finish line first in 15’35.558s, sealing a memorable double win at his home circuit. Just 0.026 seconds behind, Husni secured second place in 15’35.584s, while Fahmi claimed third at 15’35.594s to round off the podium. Dimas said, “Alhamdulillah, I was able to be the best again. Winning Race 1 already meant so much, and to win Race 2 as well, in front of my home fans, is truly unforgettable. I am very thankful to my team and especially to my family who supported me here, most of all to my father, this victory is for him.” TOP 5 FASTEST – RACE 2

Race 1 of Round 4 in the IDEMITSU FIM Asia Road Racing Championship at the Mandalika International Circuit, Indonesia delivered a thriller in the UB150 category, with home hero Dimas Juli Atmoko of RACETECH SIXTY Racing producing a sensational fightback to claim his first-ever victory in the championship. The opening lap was nothing short of chaos. While Ahmad Afif Amran of Pitsbike Superfast JRT Racing Team stormed into an early lead, the race saw a dramatic incident when April King Mascardo of UMA MMR YAMAHA PHILIPPINE RACING TEAM and Md Syamil Amsyar M Iffende of CARDINALS Factory YAMAHA ZYNERGYS Racing Team ARRC went down, forcing a shake-up in the chasing pack. A slow getaway from Dimas only added to the drama, but the Indonesian refused to give in. By Lap 2, Afif continued to control the front, but the intensity of the group meant positions were constantly changing. Fahmi Basam of YAMAHA LFN HP969 INDONESIA RACING TEAM lit up the timing sheets on Lap 3 with a blistering fastest lap of 1’55.626s, propelling himself into the lead and igniting a wheel-to-wheel contest involving more than half a dozen riders. The action reached boiling point on Lap 4 as Dimas attempted to break away from the group, only to be reeled back in, while Husni Zainul Fuadzy of ZIEAR LFN HP969 MCR RBT 34 quietly edged his way into podium contention. With every corner offering new overtakes, the 8-lap sprint turned into a test of nerves and precision. Everything came down to the final lap. In front of a roaring home crowd, Dimas launched a daring move on the last corner, seizing the lead and holding his line to the chequered flag with a winning time of 15’34.548s. Husni shadowed him across the line, just 0.080s adrift, while Fahmi secured third place only 0.039s further back, underlining the narrow margins that defined the race. Dimas teared up and said, “I am truly very grateful to be on the top of the podium. I’m so touched because this is my very first time finishing number one on the Asian stage. From Practice 1, 2, and Qualifying, I was able to get good results. Thank you to my team and crew, to my wife and child who came here to support me, and to my parents—especially my father who allowed me to race. Alhamdulillah, father, I’m number one, father! Let’s keep the spirit alive!” TOP 5 FASTEST – RACE 1 1. DIMAS JULI ATMOKO – RACETECH SIXTY Racing (15:34.548s) 2. HUSNI ZAINUL FUADZY – ZIEAR LFN HP969 MCR RBT 34 (15:34.628s) 3.

The UB150 class lit up the Mandalika International Circuit, Indonesia today in Round 4 of the IDEMITSU FIM Asia Road Racing Championship, as local talents delivered electrifying speed across the two practice sessions. With margins as slim as fractions of a second, Indonesia’s finest ensured the crowd had plenty to cheer for. In Practice 1, Danial Damar of YAMAHA LFN HP969 INDONESIA RACING TEAM stole the spotlight with a commanding time of 1’54.399s, edging out compatriot Husni Zainul Fuadzy of ZIEAR LFN HP969 MCR RBT 34 by a razor-thin 0.022s. Behind them, M. Syirat Sauki of GG Galak Galak Racing Team slotted into third with a 1’54.870s, while seasoned campaigner Ahmad Fazrul Sham of CARDINALS Factory YAMAHA ZYNERGYS Racing Team ARRC and Indonesia’s Hafizd Fahril Rasyadan of 4S1M EVO YAMAHA Racing Team rounded off the top five. The intensity climbed further in Practice 2, when Dimas Juli Atmoko of RACETECH SIXTY Racing raised the bar, producing the fastest time of the day at 1’53.439s. Fahmi Basam of YAMAHA LFN HP969 INDONESIA RACING TEAM kept the momentum for the host nation with 1’53.580s, just 0.141s adrift. Husni Zainul Fuadzy continued his strong form in third with a 1’53.680s, followed by teammate Gupita Kresna Wardhana of ZIEAR LFN HP969 MCR RBT 34 and Md Akid Aziz of Pitsbike Superfast JRT Racing Team, completing the session’s top five. With combined times shaping the early outlook, it is Dimas Juli Atmoko who leads the way as the outright fastest rider in UB150 class, though the gap to the chasing pack remains perilously close. Just 0.141s separate him from Fahmi Basam, while Husni Zainul Fuadzy lurks another tenth behind. Dimas commented, “We have been improving ourselves since Round 3 in Japan, during Race 1 and Race 2 we were looking for the right setup for the Round in Mandalika. Alhamdulillah, in Practice 1 I tried to go on my own and pushed to find where my limit is. Alhamdulillah, in Practice 2 I tried to build momentum to push forward and I managed to get the perfect result by finishing P1 in practice. For the preparation for tomorrow in Race 1, I hope I can still give my best and achieve the best result.” The narrow margins promise an action-packed weekend, with Indonesia’s contingent aiming to leverage home advantage against an equally determined regional field. As practice sets the stage, the Mandalika crowd can expect nothing less than wheel-to-wheel drama in the UB150 battles ahead. TOP 5 FASTEST – PRACTICE (COMBINED)

Not only did he score a hat-trick – a continuation of his victorious mark from Round 2 but the highly dextrous rider, Husni Zainul of ZIEAR LFN HP969 MCR RBT 34 banked in a 50-pointer flat in Round 3, instantly shooting him out of the boundaries of rivalry and onto the pathway towards stardom in the Underbone 150cc race category. Round 4 of the IDEMITSU FIM Asia Road Racing Championship which will be held at Mandalika International Circuit may just be the ground he celebrates the championship glory. Not a stranger but not a full-season rider, Husni made his appearance in 2023 as a wildcard rider in the debut season at his home-ground circuit, Mandalika. He may not have taken a win then but he certainly flaunted his prowess to finish third. In Season 2024, Husni once again marked his entry in the championship, not for a full-season but as a replacement rider. Despite his trial and error as well as limited mileage on the ARRC front, he scored two podium-finish before concluding the season seventh for his team. Fast-forwarding to where it stands to-date, Husni seemed to have taken a huge leap up in terms of input and output through the quiet strength found across the previous two seasons. The Indonesian lad with a big-smile seemed to have unlocked the door to mastery and he is unstoppable. But again, with a handful of competitive countrymen competing on a common ground, will Husni be able to ward of the threats and release the pressure? It’s a tough bet but not an impossible one and if Husni pulls it off, it will be a hat-offs moment that deserves nothing but a standing ovation. Husni said, “I am truly blessed and thankful to have won the races a number of times in this season’s underbone race category but it is not time for me to relax yet because the season has a long way to go before it ends. While the pressure is always there, maintaining my position doesn’t come as a pressuring factor but more so a motivational one. I enjoy riding and that’s the best part of it. If I were to take a double-win in Mandalika, my home-ground, it would mean an early championship title and if that happens, I will be the happiest. I have an excellent team with such great mechanics, Pak Bima and Pak Bonce who use their own data to ensure that the machine is in a perfect condition for race. That’s probably where my strength is. Of course, the fact remains that everyone in this race category has an opportunity to win but it is also luck to a certain extent. Next race in Mandalika, it is my favourite track and also of many other Indonesian riders but my best part is T15 and T16 where I will optimise more as my winning strategy. Overall, I hope to continue enhancing my riding capacities and performance in ARRC.”

You’d think that after taming a 150cc race bike at breakneck speeds, Nazirul Izzat Md Bahauddin of UMA RACING YAMAHA MAJU MOTOR ASIA TEAM would spend his free time doing something calm like fishing or napping. But, no. Instead, he grabs a tiny car, sends it flying around a plastic track, and grins like a kid on his birthday. Welcome to Nazirul’s other race track, where the engines are small, but the fun is full-sized. “If I’ve got free time, I’ll be playing Tamiya,” Nazirul says with a laugh. “It’s my way of switching gears. And apart from that, I also attend Quran classes at the mosque. It’s a balance between fun and personal growth.” This isn’t a new obsession. Nazirul’s been into Tamiya since his school days, but his love for motorcycles took centre stage for years. “I’ve been into Tamiya since I was in school, but back then I was more focused on motorcycles. Now, with a bit more time outside my racing schedule, I get to relive that childhood passion,” he shared. So what’s the draw for a professional rider who already gets to experience speed and competition on the world stage? “Tamiya is still racing, just on a smaller scale,” Nazirul grins. “The excitement’s there, the competition’s there, but it’s different enough to feel fresh. Plus, I’ve learned so many new things about building and tuning them. It’s like engineering in miniature form.” For someone used to the intense, high-pressure atmosphere of championship racing, Tamiya offers a whole different kind of joy. “With Tamiya, it’s pure fun. No pressure, no expectations. Just racing for the joy of it. It’s my stress-buster!”

Race 1 of Round 3 in the 2025 FIM Asia Road Racing Championship delivered an electrifying showdown in the UB150 category at the Mobility Resort Motegi, Japan, with Husni Zainul Fuadzy of ZIEAR LFN HP969 MCR RBT 34 emerging triumphant after a fierce multi-rider battle to the finish line. Earlier in the day, Fahmi Basam of YAMAHA LFN HP969 INDONESIA RACING TEAM stamped his authority by clinching pole position with a best time of 2’17.202s in the Super Pole session. His teammate, Husni Zainul Fuadzy of ZIEAR LFN HP969 MCR RBT 34, lined up alongside him in second with a 2’17.793s lap, while Adytya Fauzi of JPNW SND FACTORY RACING completed the front row with 2’19.177s. As the race got underway, Adytya Fauzi of JPNW SND FACTORY RACING made a strong start, but the lead constantly changed hands through every turn and every lap as the front group battled hard for control. By lap 3, Adytya and Fahmi were joined at the front by Nazirul Izzat Muhammad Bahauddin of UMA RACING YAMAHA MAJU MOTOR ASIA TEAM in third, with Dimas Juli Atmoko of RACETECH SIXTY Racing and Ahmad Afif Amran of Pitsbike Superfast JRT Racing Team rounding out the top five. Unfortunately, Ahmad Fazrul Sham of CARDINALS Factory YAMAHA ZYNERGYS Racing Team ARRC was forced to retire early due to a mechanical issue. His teammate, Md Syamil Amsyar M Iffende, was also sidelined on lap 4 for the same reason. By lap 5, Husni Zainul Fuadzy began his steady charge through the pack, skilfully working his way up to the leading group. On the final lap, the intensity peaked as every rider pushed to the limit. In a nail-biting sprint to the finish, Husni crossed the line first with a winning time of 18’36.491s. Fahmi Basam finished a mere fraction behind at 18’36.536s, while Adytya Fauzi secured third place at 18’36.667s. Reflecting on his hard-fought victory, Husni Zainul Fuadzy said, “The race was really intense, but I just tried to stay calm and focus on finding my rhythm and best pace since this was my first time racing here. Alhamdulillah, I managed to break through to the front group and take this win. I hope I can keep this momentum going and fight for a double victory in Race 2 tomorrow.” TOP 5 FASTEST – RACE 1

Round 3 of the 2025 FIM Asia Road Racing Championship unfolded today at the Mobility Resort Motegi, Japan, where Indonesia’s Husni Zainul Fuadzy of ZIEAR LFN HP969 MCR RBT 34 delivered a stunning display of speed and control, securing the fastest overall time in the combined practice sessions. In Practice 1, Husni made his intentions clear, storming to the top with a blistering lap of 2’15.097s. Right behind him was 2024 UB150 Champion Fahmi Basam of YAMAHA LFN HP969 INDONESIA RACING TEAM, who clocked a 2’15.959s. Ahmad Afif Amran of Pitsbike Superfast JRT Racing Team followed in third with a solid 2’16.501s. Husni continued his momentum in Practice 2, again leading the session with a fastest time of 2’16.866s. Afif stepped up to take second with 2’17.751s, and Dimas Juli Atmoko of RACETECH SIXTY Racing closed out the top three with 2’17.780s. Ultimately, Husni’s early pace in Practice 1 proved decisive, earning him the fastest overall time of the day. Fahmi held firm in second, while Afif secured third in the combined results—setting the stage for a fierce qualifying battle ahead. Husni said, “Thankfully, from Practice 1 to Practice 2, my performance has shown improvement. We’ve also found the right setup. Practice 1 was held in dry conditions, but in Practice 2, the weather began to turn rainy. Despite that, I still managed to find a good setup. I hope to achieve the best possible result tomorrow.” TOP 5 FASTEST – COMBINED PRACTICE
