G-Force 90STD and 90SE UL engine mount:

. Idea for further weight reduction for those putting the R90 on a diet.
. Increase frame contact area to reduce frame torsion loading.
. Effective upgrade for those that do not run side stiffeners.
. Weighs 36 grams, which is 40% lighter than the stock engine mount.
. CNC machined
. Mounting holes for 91 OS,YS and Webra engines.

Note: We have found the 2.5mm thick TT CF frames provides adequant rigidity and the aluminum side stiffners can be omitted with the R90 UL engine mount.
