Supersports 600

As the IDEMITSU FIM Asia Road Racing Championship enters the 2026 season, Herjun Atna Firdaus stands at the center of a new era for ASTRA HONDA RACING TEAM in the SS600 category. With former teammate Mohammad Adenanta Putra stepping up to ASB1000 and newly crowned AP250 Champion Fadillah Arbi Aditama joining him in SS600, Herjun faces a fresh mix of pressure, opportunity, and motivation. Last season, Adenanta’s strong performances cemented Honda’s presence in the front group. This year, eyes naturally turn to Herjun, now one of the riders expected to carry forward Honda’s momentum in a highly competitive field. But Herjun remains grounded and focused. “I don’t really think of it as ‘my moment’ or a bigger role. But what I can promise is that I will give my absolute best for the team. Every season is a chance to improve, and I want to grow step by step while making sure I contribute positively to ASTRA HONDA RACING TEAM in this category.” With Arbi joining him, fresh from a dominant title-winning season in AP250, the internal dynamic at ASTRA HONDA RACING TEAM takes on a new dimension. While some riders might feel pressured by a fast teammate stepping up, Herjun sees it differently. “I don’t feel any pressure from having Arbi as my teammate. My focus is always on my own race. But seeing the impact Adenanta made last year, especially with such strong results, motivates me more than anything. It shows what is possible on the Honda. I still have so much to learn, and I want to keep improving so I can match that level.” When asked how he plans to stay ahead of Arbi as the more experienced SS600 rider of the two, Herjun answers humbly but with determination. “Of course, I’ll try my best. Having a champion like Arbi beside me pushes me to be sharper. It’s a healthy motivation because we both want to lift the team. The goal is not just to race each other, but to raise the overall performance of Honda in SS600.” Looking at the wider field, Herjun acknowledges the rising competition in 2026, with both seasoned contenders and emerging threats filling the entry list. “The field this year has many strong and experienced riders. I know the 2026 season won’t be easy at all. But I also know I have to believe in myself. Confidence is important. If I stay focused on improving every session and every race, I can fight for a strong position in the championship.” To handle the growing competition, Herjun has worked closely with the team to ensure he is ready for the challenge technically, mentally, and physically. “We’ve been working hard on getting the best setup to fight the Yamaha bikes because their acceleration was very strong last season. There are many areas I want to improve, and the team is supporting me a lot. This season, I want to show better performance than last year, and hopefully fight closer to the front.” As the season opener at the Sepang International Circuit approaches, Herjun carries a blend of calm focus and renewed ambition. With leadership changes, new team dynamics, and increased responsibility, 2026 could become a defining year in his SS600 journey. ASTRA HONDA RACING TEAM believes in him. His fans believe in him. And now, it’s up to Herjun to show the next step of his growth.

Kasma didn’t expect to hear his name. Who would have guessed that a few slightly better finishing positions could decide an entire championship? For Kasma Daniel Kasmayudin of HONG LEONG YAMAHA RACING, that was exactly how the SS600 category of the IDEMITSU FIM Asia Road Racing Championship 2025 unfolded. After finishing fourth in the final race, while his closest rival, Anupab Sarmoon of YAMAHA THAILAND RACING TEAM came third, Kasma was convinced the title had slipped away. The announcement that he was the overall champion left him both surprised and elated. The championship had been claimed by a razor-thin edge of consistent performance. After last season in ASB1000, Kasma returned to SS600 and had to readapt to the class, the competitors, and the rhythm of the category. Yet the familiarity of SS600 worked in his favor. He didn’t need to dominate every lap. He rode intelligently, made the most of every opportunity, and let experience guide him when the stakes were highest. Each podium, calculated overtake, and point collected reflected the adaptability, skill, and racecraft honed over years at the highest levels. When the championship was finally confirmed, Kasma Daniel Kasmayudin didn’t just claim the SS600 title. He turned a season of uncertainties into a triumph even he hadn’t fully anticipated. And now, with the 2025 season etched into history, what remarkable moments will Kasma deliver next?

The final race of the IDEMITSU FIM Asia Road Racing Championship 2025 at the Chang International Circuit, Buriram, Thailand delivered one of the most dramatic and unpredictable SS600 showdowns. Race 2 concluded with Thanat Laoongplio of HONDA RACING THAILAND won home race, and Kasma Daniel Kasmayudin of HONG LEONG YAMAHA RACING crowned as 2025 SS600 Overall Champion. As the race started, Anupab Sarmoon of YAMAHA THAILAND RACING TEAM launched strongly from the grid. However, his early advantage was short-lived as Kasma Daniel Kasmayudin of HONG LEONG YAMAHA RACING and Thanat Laoongplio of HONDA RACING THAILAND swept past to take control. By the second lap, the running order shifted again when Apiwath Wongthananon of YAMAHA TNP slotted into the lead, followed closely by Thanat and Kasma. Behind them, Mohammad Adenanta Putra of ASTRA HONDA RACING TEAM carved his way through the pack, overtaking both Kasma and Anupab to climb into third place. The intensity increased as the riders entered the middle stages. Adenanta continued his charge, challenging Thanat and closing in on Apiwath. The two leaders exchanged positions repeatedly, with Thanat momentarily seizing the lead before Apiwath retaliated. Meanwhile, Aldi Satya Mahendra of YAMAHA RACING INDONESIA produced a strong surge of his own, overtaking Anupab and gradually inserting himself into podium contention. The race reached a boiling point around lap 6, with Aldi moving up to second place while the front group compressed into a tight, unpredictable six-rider battle. By lap seven, Adenanta briefly took control of the race before Aldi countered to reclaim the lead. The following laps were defined by fierce but clean racing, with Aldi, Kasma, and Anupab locked in a high-speed contest for first place, while Thanat, Adenanta, and Apiwath traded blows for fourth. With the second group rejoining the leaders by lap 10, the fight for the win became a six-way sprint. Thanat produced the fastest lap of the race at 1’39.582s, re-entering podium contention just as the field approached the final lap. What happened next dramatically altered the course of the championship. In the last-lap chaos, Anupab made a decisive move to overtake Aldi and capture the lead. Adenanta then executed a brilliant overtake of his own, momentarily placing himself in position to win both the race and potentially the championship. However, disaster struck when he crashed out, ending his podium hopes and his season-long title pursuit in a single moment. The opening created by the incident allowed Thanat Laoongplio to sweep through and claim a sensational victory on home soil with a winning time of 20’07.296s. Aldi crossed the line in second at 20’07.458s, followed by Anupab in third at 20’07.647s. Despite missing out on the podium, Kasma’s strategic race management and consistent performance watched him secured the SS600 Overall Championship title for season 2025. He ended the season tied with Anupab on 167 points, but his overall results across the year placed him at the top of the standings. Adenanta concluded his campaign in third with 152 points after his unfortunate final-lap exit. Thanat said, “I have waited for this moment for so long! This is my first victory of the season, and winning on my home soil makes it even more meaningful and special. This one is for everyone who never stopped believing in me and has always supported me.” Kasma said, “This is truly a gift from Allah. I still can’t believe it. During the race, I was really nervous and focused on staying safe, just trying to stick with the front group without crashing and hoping for the best. But as I said, this is a blessing from Allah. Even though I didn’t finish on the podium today, I still secured the title. Alhamdulillah, Allah’s grace is boundless.” TOP 5 FASTEST – RACE 2 1.

  SuperSports 600cc race category of the IDEMITSU FIM Asia Road Racing Championship certainly unveiled a twist and the unexpected side of home-boy Syarifuddin Azman of IDEMITSU HONDA RACING MALAYSIA in Round 5 who emerged with a flawless strategy to swipe a victorious double-win, instantly defeating chart topper Adenanta Putra of ASTRA HONDA RACING TEAM and fellow countryman, Kasma Daniel of HONG LEONG YAMAHA RACING. While his chances of making the top three cut are slim, the odds have definitely been a valuable lesson that nothing is impossible in motorsports. With an 8-point difference between Adenanta and Kasma, it boils down to the implementation of strategies including taking calculated risks, managing expectations and moving swiftly against the motion of pressure in the season finale. Both the riders from the neighbouring countries have stamped an exceptional track record in the race category throughout the season with Adenanta holding superiority after marking seven podium-finish including four wins however the challenges inevitably lie in the unexpected nature of the sports and with that, it is a matter of luck and time when a twist of fate could potentially redirect the course. As for Kasma who has withdrawn from the limelight of the premier race category this season, his strategy in SS600 has certainly created waves while simultaneously adding on to the already mounted pressure among the rivals and right now, evidently on Adenanta who will be facing the brunt of rivalry directly from Kasma. Who will withstand the challenges of the circuit? In Round 1, Adenanta celebrated his first victory for the season in Race 1 but he was defeated by Kasma in Race 2. While their level of competencies match, the minor differences is all that matters. Commenting on the upcoming race, Adenanta said, “The coming race is about to get heated for sure. But of course, I want to do my best and avoid mistakes as much as I can although it’s not an easy task considering the close contention from Kasma and Anupab. Let’s see how it goes. The goal is to make it and I hope that while I am at that, luck will also be on my side. It’s just two races but the weekend will surely be a long one – a lot of hard work not only on my side but also on the crew and mechanic’s side. We will look for the best settings for the machine which will help me optimise my performance and with the strategies in place, we hope to make the best and most of the weekend.” “Chang circuit can be tough depending on our riding styles and techniques. It has many stop-and-go corners and exiting the corners is key during racing. The strategies have to align with this and fine tuning my riding techniques are crucial for this. I am 100% compatible with the machine and I think I have found my comfort spot while riding it so I have no issues in that aspect. This season has been a wonderful one for me – almost perfect with its ups and down and the successes and achievements are definitely attributed to my team who has always supported me through good times and bad times. If I own this championship title, this would be the best motivation for my future career.”

Round 5 of the IDEMITSU FIM Asia Road Racing Championship saw an exhilarating Race 2 in the SS600 class at the Sepang International Circuit, as Malaysia’s Muhammad Syarifuddin Azman of IDEMITSU HONDA RACING MALAYSIA secured his first double win on home soil.At the start, Kasma Daniel Kasmayudin of HONG LEONG YAMAHA RACING got off to a strong launch, followed by Muhammad Adenanta Putra of ASTRA HONDA RACING TEAM and Syarifuddin in third.

Adenanta settled in third, followed by Wahyu Nugroho of YAMAHA RACING INDONESIA and his teammate Muhammad Faerozi Toreqottullah. On Lap 3, Syarifuddin clocked the fastest lap of 2’09.936s, keeping Kasma under pressure as the top two riders pulled a one-second gap from the chasing group. Lap 4 saw Syarifuddin close in on Kasma by 0.147s, with the gap to the second group gradually extending to two seconds by Lap 7. Adenanta held third, while Wahyu and Faerozi rounded out the top five. The decisive moment arrived on the final lap when Syarifuddin seized a daring opportunity on Turn 8 to overtake Kasma. He accelerated decisively and pulled away, crossing the finish line first at 21’50.647s, securing his second victory of the weekend. Kasma took second place at 21’51.524s, while Adenanta completed the podium at 21’53.088s. Syarifuddin said, “I would like to say a big thank you to my team for giving me so much confidence on the bike. During the race, I really enjoyed the opening lap, and then I set the fastest lap time of 2’09.697s. At the end, I tried to find a way to overtake Kasma on the final lap. Kasma blocked the line very tightly, but I saw a small space to pass him, and finally I got through and secured a double win. This is the first time I’ve achieved a double win here on home soil. I can’t even describe how happy I am. Thank you so much to all the supporters who came to cheer for all the Malaysian riders. I love you all!” TOP 5 FASTEST – RACE 2

The hot conditions tested the riders’ tyre management as Kasma remained in front, closely shadowed by Syarifuddin. Helmi and Adenanta exchanged positions multiple times, showcasing a thrilling Malaysian trio at the front. By Lap 8, Syarifuddin sensed his opportunity as riders began losing grip under the searing heat. He overtook Kasma and gradually pulled away, demonstrating exceptional control and strategy. On the final lap, Syarifuddin maintained composure, crossing the line first in 21’57.501s. Kasma finished second at 21’59.192s, while Thailand’s Anupab Sarmoon of YAMAHA THAILAND RACING TEAM executed a daring final-turn move to snatch third at 22’04.769s, just ahead of Helmi. Syarifuddin expressed, “We knew that in the hot conditions we had better pace, but at the start I focused on following Kasma because he also has a solid pace here. Towards the end, I noticed Kasma struggling a bit with the rear, so I knew it was my moment to attack. I really enjoyed the race and want to thank everyone who supported me, especially my wife. Her support at home means a lot. If she were here today, it would have made this victory even more special.” TOP 5 FASTEST – RACE 1

The Indonesian flag raised at the podium post SuperSports 600cc of the IDEMITSU FIM Asia Road Racing Championship was a testament to the wit and grit of Indonesian riders, Md Adenanta Putra and Herjun Atna Firdaus of ASTRA HONDA RACING TEAM who graced the top spot in Race 1 and 2 respectively at their home-ground. The real question is though, while Adenanta has tamed his machine on various circuit grounds, can Herjun trail his footsteps and ward off the pressure from home-boys in Round 5 that will be held at Sepang International Circuit? It was unfortunate that Adenanta slipped and fell in Race 2 at Mandalika before savouring the sweet success of a double-win but his teammate, Herjun was quick to fill in his space to ensure the 25-points remain intact within their team. The heat of rivalry is bound to get hotter for the Indonesian lad who has just found his fame, especially on a circuit ground more familiar to aggressive players such as Kasma Daniel of HONG LEONG YAMAHA RACING and Md Helmi Azman of IDEMITSU HONDA RACING MALAYSIA who have clocked not only impressive lap times but also marked victorious in their pursuit. In Round 2, Kasma bagged the second spot in Race 1 and Helmi took the winning prize in Race 2. The capacities of the riders are clearly undeniable especially in a game where mileage adds up to their advantage. Between the duo, Kasma has whipped up a storm throughout the season and sits pretty at the third spot overall with only a 1-point difference with his closest contender, Anupab Sarmoon of YAMAHA THAILAND RACING TEAM. Helmi, although his light has dimmed a little this season, his competitive stride is nevertheless evident in all races and is expected to fire up once again on his home-soil. Commenting on the race, Helmi said, “This year would be considered the toughest season for me because as we have observed, there are many competitors who are closing in really fast in terms of machine performance. We definitely have more to improve on the capacities of the machine so that we can remain competitive among the top scorers. As for myself, hard work is always a must and that is what I will be doing to be on par with the counterparts. Sepang being my home-ground does not make it easier for me but I am for a double-win. I have to take advantage of the home-ground factor if I want to see better results, more so after the struggles we have faced in the last couple of rounds. I believe that we can make a comeback.” “Having said that, I know it will require some new strategies. Although Sepang is my home-ground, other riders are also quite familiar with the track layout. Most importantly, the goal is not to over-pressure myself. I hope to remain calm and composed throughout the weekend and ride through the familiarity, without any major issues with the machine. There are also added value for me here. I will surely have the support of my fans and family members so, with that in mind, I hope to draw some courage and do better. Preparations are as usual – the workouts to build my physique and my mental capacities. The team has also given us some mileage through bike trainings. So, let’s see how it goes. Since on paper, I can still fight for the top three positions, that will be aim for now and I will do my best to ensure I’ve given my all.”
