Yamaha SW396 Snowmobile (1970)

The 1970 Yamaha SW396 is an iconic snowmobile model, though the 1970 model year for 396cc Yamaha snowmobiles was primarily represented by the Yamaha SS396. This 396cc twin-cylinder engine produced 36 horsepower, known for its performance partly due to a 'pulse-tuned' muffler design. It was offered as a single model without distinct trim levels for this year. It is important to note that, according to official Yamaha history, the SW396 model, notably featuring reverse gear, was introduced in 1971. Therefore, specifications for a 396cc Yamaha snowmobile in 1970 are generally attributed to the SS396. There were no mid-cycle generation or engine changes for the SS396 in 1970. Broader evolutions, such as changes from 5-port to 7-port cylinder designs and the 396cc engine evolving into the GP396, were later developments not applicable to the 1970 model year.
