Fork angle different to steering head angle

[brent j]

Something I noticed while putting my RL together today, the top and bottom triple clamps appear to have different offsets. The fork legs are on a different angle to the steering head. The rake angle is not affected but having the forks on a flatter angle effectively increases the offset of the axle and so reduces trail. I can only assume that as the suspension compresses the rake angle gets steeper but the offset reduces and slightly increases the trail. Theoretically giving an increase in trail and stability.
Yamaha TY250's (twin shock bikes) are set up the same way with the forks on a different angle to the steering head
