NOTE: These are true numbers off of Dale's in-house dyno. The Holeshot compound is about 200 feet above sea level and the dyno room stays a constant temperature between 70-80° F. The above results were also achieved with Dale's tuning, which is a bonus!

Be aware that dynos, dyno operators, conditions and bikes can vary 3-8 HP, so these numbers should only be used as a reference.

These are true numbers measured on Dale's Dynojet 250 I dyno with WinPEP 7 Dyno Run Viewer, STD Mode, Smoothing 5.
