A two-stroke 200cc motorcycle, the Yamaha CS3 was a parallel twin that was also known as the RD200 in other markets. It featured a five-speed transmisison and an oil injection system, which helped the bike perform much better than you might expect a 200cc bike to run. This specific example should run just fine as it has recently received a new top end. Find this Yamaha CS3 for sale here on Craigslist in Dayton, Ohio for just $1,950.
