hi, motocross action november 73 issue has a 12 page dual test on the yz250a and 360a. Cycle,Cycle World,popular cycling,motorcyclist,Dirt bike and cycle guide all ignored the yz360a during 1973 and 74. I have most of the 73/74 modern cycle ,cycle illustrated,dirt cycle,cycle rider and early dirt rider and no 360a tests. Cycle december 73 issue dynoed the yz250a-26.85 rear wheel hp @ 7500,and 19.49 ft/lbs @7000.
yz250a hp figures, 9.41@4000 10.87@4500 12.33@5000 15.12@5500 19.27@6000 23.57@6500 26.00@7000 and 26.85@7500
-may cause some debate. cheers g.
