Fabricated using .120 wall A513 Grade B Steel Tubing and gusseted in all critical areas.  
 
This frame rail used the factory Yamaha YFZ450R engine mount location.
 
This rail is around 5 lbs heavier than the OEM rail but will take abuse for a very long time!
 
If you would like one without the mount check out our Hybrid page.
