1972-1982 Suzuki RV125 Vanvan Service Repair Workshop Manual PDF
VEHICLE/EQUIPMENT INTRODUCTION:
The Suzuki RV125 Vanvan is one of the most distinctive and endearing motorcycles ever produced, earning its name from the Japanese word for "slow coach" or "dawdler" which perfectly captured its relaxed riding character. Introduced in 1972, the Vanvan was designed as a fun, practical, and highly capable motorcycle for mixed on-road and light off-road use. Its wide fat tires, high fenders, and upright riding position became iconic, foreshadowing the modern adventure and scrambler motorcycle trends by decades. Powered by a 123cc air-cooled two-stroke single-cylinder engine with a rotary valve induction system, the Vanvan was reliable, lightweight, and incredibly easy to maintain. Over its production run from 1972 to 1982, the RV125 underwent minor refinements while retaining its core identity as a versatile, approachable motorcycle. It found a devoted following among casual riders, beach-goers, farm workers and anyone who valued its unique style and go-anywhere simplicity. Today, original Vanvans are sought-after collector motorcycles that represent a fun and unpretentious era of motorcycling.
