Technical Overview
The Yamaha XQ 150 Maxster, internal code SE061, represents a pivotal era where Yamaha attempted to merge the agility of a sport-scooter with the comfort of a maxi-scooter. Powered by a liquid-cooled, 4-stroke single-cylinder engine, the SE061 delivers a linear power curve suitable for both urban navigation and short-distance touring. Its 13-inch wheels provide a balanced compromise between flickability and high-speed stability.
Maintenance Guidelines
Engine Lubrication
To maintain the integrity of the liquid-cooled engine, MotoSpecsLab recommends using a high-quality SAE 10W-40 JASO MB lubricant. The JASO MB specification is critical as it is designed for scooters with centrifugal clutches, ensuring reduced internal friction and better fuel efficiency. Total capacity is 1.0 Liter.
Ignition and Electrical
The NGK CR8E spark plug is the heart of the SE061’s ignition system. We recommend inspecting the gap every 6,000 km to ensure optimal combustion. For starting reliability, the Maxster utilizes a GT7B-4 battery; ensure terminals are free of oxidation to prevent voltage drops.
Chassis and Safety
Tire maintenance is paramount for the Maxster’s unique handling characteristics. The front 120/70-13 and rear 130/70-13 tires must be kept at 29 psi (2.0 bar) and 33 psi (2.3 bar) respectively. Under-inflation will significantly degrade the precision of the SE061’s rigid frame geometry.
