Cr125re 1984 sprocket ratio

[Paul552]

Nearly finished my CR125re so I am trying to find out what the standard sprocket ratio was on the bike.
 Currently it has 13front 53 rear.
Does anyone know what the standard ratio is? I dont really want to experiment  and buy up stuff I won't use. I will use it for VMX so any recommendations are appreciated

Thanks Paul

13-51 is standard,I use those ratios on my 125RF,seems to work well for me
