Oneway diff fr S7XX
The drag assisted one-way for the Serpent 750 is a very nice option.
Replacing the normal front diff, it enables you to still brake and turn in like a diff but the exit drive and change of direction on-throttle is much better.
It is important though to adjust the oil viscosity according to the available grip level.
With lower grip level you should go to thicker oil to get more front braking power.
This innovative device has the case made from a special magnesium alloy. The total weight could be limited to only 22g!
