Recommended Oil for Dirt Bike Premix
High-performance synthetic 2-stroke oil like Maxima Castor 927, Motul 800, Amsoil Dominator, or Bel-Ray H1R. Racing oils allow leaner ratios (40:1-50:1) vs. standard oils (32:1).
Always Check Your Owner's Manual
Using the wrong fuel ratio can damage your engine. Break-in period may require richer ratios. Many riders use 32:1 during break-in, then switch to 40:1 or 50:1 with synthetic oil.
