The Yager 125 uses 82mm or 3.2" contra spring (or movable face spring).
The Yager 200 uses 130mm or 5.2" contra spring.
I cannot find any specs on the aftermarket or GY6 generic springs
to know if they might give us a choice on the Yager?
It amazes me that people selling online do not give any info. Many times I
am looking for a custom solution and they say "Red Spring" or "For Jojo 50"
Why not length and diameter?
