The Reaper 543 cam feels strong on the road in the low to mid RPM range. Nice & smooth for a bolt in cam for a 103ci.
It gave a nice increase in Horsepower & Torque across the board from 2250-4000rpm, but it will still pull strong to the rev limiter if required.
87.0 -> 99.3
(12.3 HP increase / 14.1% increase)
99.4 -> 105.3
(5.9 ft-lbs TQ increase / 5.9% increase)
* Bike had a stage 1 setup
