The upcoming ARRC Round 5 will also mark the first time the Underbone 150cc class will be racing at the Zhuhai International Circuit.

This special South East Asian heritage class, has been gaining fans everywhere the series is hosted. Small in stature but certainly not in speed, the Underbone 150cc presents a tough, gritty, close-contact racing that is rarely seen in bigger full-frame classes. Complete with ECUs and kitted out with Dunlop Moto3 tyres, the UB150 class of the Asia Road Racing Championship is the pinnacle of Underbone racing.

29 bikes will take to the grid at the Zhuhai International Circuit with riders coming from Malaysia, Indonesia, Thailand, Philippines and Vietnam.

After a wet and wild outing at the Suzuka Circuit in Round 4, Indonesian rider Wawan Wello has taken provisional control over the UB150 title chase. In a race category characterized by its sheer unpredictability, Wawan’s performance has remained relatively consistent with two back-to-back second place finishes. The SND Factory Racing Rapido rider takes over the top of the championship standings with 79 points, 12 points ahead of previous leader, McKinley Kyle Paz.

Despite a blazing start to his full-season debut in the Underbone 150cc class, Filipino rider McKinley now finds himself tied on points with his Uma Racing team mate, Mohd Akid Aziz. Both riders will be looking to break the tie in Zhuhai.

Meanwhile, Team One For All’s seasoned campaigner, Mohd Affendi Rosli has dropped to fourth overall after finishing out of the points at Race 1 in Suzuka. Of the 29 riders on the Zhuhai grid this weekend, only a few senior riders have had experience on the 4.319km track. Affendi Rosli is one of them, along with Rozaiman Said from the Cardinals Racing Team and Mohd Adib Rosley from the RCB Accentwire Yamaha YY Pang Racing Team.

Other interesting riders to look out for include Yamaha Racing Indonesia’s Aldi Satya Mahendra. In the previous round, 13-year-old Aldi set a championship record as the youngest UB150 winner.
