So what's the concensus on ideal sprocket size for the YZ426 for mx/enduro? Even though I've learned to keep the RPM's up slightly when landing jumps and cornering, I still can stall the beast in the corners occasionally-which I'm sure the 48T rear contributes to. Does the 51T limit top-end too much for XC? And what about chains - DID or Renthal? O-Ring or not? Steel Rear sprocket or Aluminimum? Everyone has their preferences but majority rules-usually.
