The different
damper valve cartridges .
MGF Trophy IS different to MGF Standard !
AND the front is different to rear in ALL cases.

Accuracy of above measures may be +/- 0.5mm |

See the different shape
of the metal cover (D metal cover)
Looks like the more load, the smaller is the lower diameter.
The ally piston shape reffers as well to the load.
Low weight on the axle means less diameter, but longer height.
All pistons nearly have the same lenghth overall. |
 |
| Front Metro and front MGF sheet
metal shape is nearly equal form, but the MGF open diameter is much wider. |
