Kwak 500 v breathed on RD400

[John Ritter]

Biggraham stated Pipes & Carbs as being" breathed on", that is why I went with the Kawi. Now, as to motodreams description of the overall bike I mirror his comments. I've ridden S1, S2, S3, H1 & H2 and think the H1 & H2 are a handful. If i remember correctly some of the 500cc drag bikes used 400 frames, maybe Shultz ??
