The SYM Sport Bonus 115 SR is a compact underbone-style commuter motorcycle designed for urban riders seeking reliable, straightforward transportation. Its lightweight build and modest 115 cc engine make it well-suited for daily commuting, errands, and navigating city traffic. With simple controls, electric and kick start options, and a familiar underbone layout, it appeals to riders who value ease of use, fuel efficiency, and low maintenance costs. Ideal for students, first-time riders, or budget-conscious commuters, the Sport Bonus 115 SR offers a practical balance of performance and simplicity.
In Malaysia, the SYM Sport Bonus 115 SR was offered as a 113 cc, air-cooled, 4-stroke SOHC underbone motorcycle with both electric and kick start options. It delivered around 7.1 hp at 7,500 rpm and approximately 7.9 Nm of torque at 4,000 rpm, paired with a 4-speed manual transmission and automatic centrifugal clutch. The bike weighed about 96 kg and featured a 4‑litre fuel tank, delivering fuel consumption of roughly 55 km per litre at 90 km/h. Braking was handled via a front disc and rear drum setup, while the chassis used a pipe-backbone frame with telescopic front forks and swing‑arm rear suspension. Available in red, blue, and yellow, the model has since been discontinued in Malaysia.
