Frame Structure : 
This Yamaha original design incorporates a sub-frame just below the rocker shaft to deliver greater stability and durability. Drummers will experience smoother, more stable movement particularly in double pedal setups since bearings for both the main and remote beaters are incorporated into the sub-frame.
