Other things being equal, however, makers of motorcycle engines have tended to end up with rod ratios in the aforementioned 2.0–2.2 range. People talk about mysterious gains to be had from "increased piston dwell" resulting from the use of smaller rod ratios, but the only published dyno data I have seen is from a long-ago issue of Circle Track. Two 350ci V-8s, identical in such variables as piston weight, compression ratio, valve timing, etc. were tested with longer and shorter rods. Although there was one point on partial throttle where the short-rod engine was superior, the test's conclusion was that long rods are best overall.
