I didn't like the feel of the MT12's steering, so I modified it.

1) I removed the burr in the hinge pin hole of the lever so that the lever could move smoothly.


2) I removed the looseness of the bearing (850ZZ) on the back side of the steering shaft.

3) I removed the initial tension of the return spring and increased the spring rate.
I prefer a stiffer spring, so I set the number of turns to 11 turns.


The free length of the spring was set to a little over 15mm so that the pretension could be adjusted to 0.


With the above modifications, the steering feel of MT12 has been greatly improved.
