“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.

This example is VIN: 1A1310910, Engine #: 1A1310910. The owner purchased the bike a year ago from a private seller in Kansas.

During his ownership, the seller has covered 600 miles. The odometer shows 13,565 miles.

Recent Maintenance
The seller states that “the engine was recently rebuilt (less than 100 miles) to include new 65mm pistons/rings/wrist pins and bearings, crank bearings/seals, all engine gaskets and seals replaced, new clutch plates, carbs cleaned, front brake caliper and master cylinder rebuilt, new fork seals.”

“The high beam is out but other than that all lights, switches, and electrical components work as they should.”
