Valkyrie Dyno Day at Sportland 2....
Dyno used is a SuperFlow Cycledyn A note about horsepower.... comparing to often published horsepower figures you'll see these *appear* roughly 10% low. The most commonly
used dyno is the Dynojet brand. The Superflow is nearly twice the cost and is built by the same people who build dynos used by OEMs, factory race teams and emission test stations.
Feel free to check out the CycleDyn at All tests were run with the "Controlled Acceleration" test
using the Eddy Current absorber. The Eddy Current loading will pinpoint problems that will often go unseen on an inertia only dyno. Fourth gear rolling then WOT. If it tests good here it's good.
All bikes plotted together (smoothing to match data points)
