“Cool doesn’t even come close.” That’s how Visordown summarized the iconic RD400 in one sentence, but the longer story isn’t very complicated, either. The RD400 came about when Yamaha made the RD350 a bit bigger in 1976 – displacement was 399cc. Thanks to 44 horsepower, the bigger RD was capable of hitting the ton with a top speed of 105 miles per hour.
Most people know the 400 simply for being an easier to ride upgrade over the 350, but it was also notable for being the first production motorcycle to feature cast wheels as standard. The 400 motor was more than a bored out 350 unit – Yamaha increased the stroke and in doing so they had to build new crankcases as well. The bike weighed about 350 pounds, and it was the most popular two-stroke sportbike of its day.
