We have a Kasea 90 for my son. This quad is mainly used for trail riding but he wants to try some motorcross and TT events this year. We have GT Thunder +2 arms and good shocks up front. Have an Elka rear shock with a "homemade" +2 swinger that came with the quad. The quad also came with the stock swing arm. My question here is about the swingarm. I dont like the hack job of the the extended swingarm...... Should I go back to the stocker or would an Apex or DRR stock swing arm be any better for us? Also need to widen out the rear to match the front. I have wheels spacers but also was wondering if there is a different stock stlye axle that would fit but still widen it out without wheel spacers.

Any thoughts would be appreciated
