Powroll - 4 Stroke Performance
 
 

 

STOCK SPECIFICATIONS:   

39mm Bore x 41.4mm Stroke

FYI:  Although externally similar to the Z50, the Honda XR and CRF 50 internals are significantly different from the Z50.  No performance parts are readily interchangeable. 

Chinese and Taiwanese engines which are 'like Honda' design are not copies of the CRF or XR.  These engines share similarities to a variety of Honda engine designs, but aren't the same as any ONE Honda engine.
