The Thumpstar TSR 140 SW (2023) is a small-wheeled dirt bike powered by a 140cc engine, making it ideal for younger or smaller riders. Its 4-speed gearbox provides a manageable range of gears for learning the fundamentals of off-road riding. With a top speed of 90 km/h (55.9 mph), the TSR 140 SW offers enough performance to be exciting without being overwhelming for its target demographic. Featuring an 830mm (32.7 inches) seat height, the TSR 140 SW allows for good ground reach and control, crucial for building confidence in young riders. The front suspension is handled by VS1 inverted forks, which should provide decent damping and control over rough terrain. The single disc brake with a dual-piston hydraulic disc at the front offers adequate stopping power for the bike's size and weight. With a fuel tank capacity of 3.4 liters, the TSR 140 SW allows for reasonable riding time between fill-ups. This bike is well-suited for children and teenagers who are new to dirt biking and want a reliable and easy-to-handle machine to develop their skills. It offers a good balance of performance, handling, and accessibility for its intended rider base.
