The Sanyang wind speed in 1994 originated in Taiwan Province Province. If it is two-stroke, it is air-cooled. Two-stroke car muffler emits blue smoke, and four-stroke car does not smoke. If it is four-stroke, it is water cooling. The water-cooled engine has a water tank and corresponding water pipes, the cylinder head is smooth, and there are not so many fins, so it is easy to distinguish. The quality and performance of the original wind speed are very good. As long as it is properly maintained, it is very comfortable to ride, but this car is a few years old and I don't know how it is. Sanyang, Taiwan Province Province is a joint venture with Honda. Its early engine was Honda. Later, when its wings hardened and flew solo, it gradually used the Sanyo trademark of SYM. That is to say, this engine may be Honda's, or it may be a product assembled by Sanyang and certified by Honda.
