Why This Part is Essential
The 1978 YZ80E frame was notorious for cracking under racing conditions. Yamaha released this gusset kit as a "factory fix" before redesigning the frame for the 1979 "F" model. For a high-end, period-correct restoration, this kit is an essential "Day Two" modification that adds both structural integrity and historical accuracy to your build.
