About the 1998 Yamaha RT 180

Simply put, RT180 is one of the best values in a performance-oriented play bike. Bridging the gap between the high-performance YZ125 and the entry-level RT100, the RTl80 features a lively 176cc two-stroke engine with a six-speed transmission and manual clutch to provide spirited off-road performance.

Like the other members of the Yamaha play bike family, the RT1 80 features the Automatic Oil Injection system which eliminates the premixing of gas and oil. The maintenance-free CD ignition creates a hot spark for easy starting and strong engine performance. The RT180 also features a 3.4 gallon fuel tank for extended rides and more fun between fill-ups. Harsh off-road terrain is absorbed by 7.9 inches of front travel and a spring preload adjustable single-shock, monocross set up in the rear. Braking performance is enhanced with a 245mm front disc brake and a rear drum system.

To add to its off-road prowess, the RTl80 has a low seat height of only 33.9 inches and weighs only 216 pounds making it easy to handle in tight conditions.
