Vietnam
Yamaha Exciter 150 (called in Vietnam) was first launched in 2014, replacing the 135 model. It had a brand new 150cc liquid-cooled engine (the previous had a 135cc liquid-cooled engine), combined with a 5-speed constant mesh manual transmission. In 2018, this bike received an update, with some design changes and new technologies (LED headlights, LCD instrument panel, passing button, on/off engine switch and Answer back key). In 2020, a brand new version was released in Vietnam, called the 155 VVA. It had a new 155cc engine with VVA "Variable Valve Actuation" technology developed from the R15 that according to Yamaha Vietnam was 17% more powerful than the 150cc engine version, a new 6-speed constant mesh manual transmission and an A&S "Assist & Slipper" Clutch that allowed for 20% lighter clutch work and reducing back-end torque when downshifting aggressively. In September 2023, the 155 VVA version received a minor update, including the engine now producing 17.9HP (0.2HP more than the pre-facelift version) and slightly better economy (1,91L/100km for Standard trim, 1,99L/100km for Premium, Limited GP trim compared to 2,09L/100km for the pre-facelift version on all models). The bike is also available with ABS "Anti-lock Brake System" on the Premium and Limited GP trim (there are 2 models on the Premium trim: with or without ABS). Yamaha Vietnam is selling both the 150 and 155 VVA as for now.
