The Yamaha MTβ15 is a compact naked street bike in Yamahaβs MT (Master of Torque) family, designed for riders who want sporty performance in a nimble, urbanβfriendly package. It shares its 155β―cc engine with the popular R15 but offers a more upright riding position, making it wellβsuited for daily commuting, weekend rides, and those who value agility over outright sportbike ergonomics. Ideal for both new and experienced riders, the MTβ15 delivers accessible power, manageable weight, and a distinctive streetβfighter style that stands out in traffic.
In Malaysia, the Yamaha MTβ15 sits in the entryβlevel naked sport segment, powered by a 155β―cc singleβcylinder, liquidβcooled engine with Variable Valve Actuation (VVA), producing around 19β―hp and 14.7β―Nm of torque, paired with a sixβspeed gearbox featuring assist and slipper clutch. It rides on a lightweight diamond (deltabox) frame with gold inverted front forks and a preloadβadjustable rear monoshock. Braking includes front and rear discs with dualβchannel ABS as standard. For 2025, Malaysia gets a new βIce Stormβ colour alongside Midnight Black, with the price unchanged at around RMβ―12,498 (excluding insurance and registration).
