Got my G.T. 1st pre order batch last October. I just bought brake pads and the suspension components to have on hand when ready to replace. (May I stress “when Ready”. Not sure how many miles on her as I write this review, but it’s peace of mind having them for when they do go.
The stock bushings on my Kaabo Wolf King GT Pro started to crumble after ~1,500 miles on the odometer, so I finally had to replace them.
What ends up happening is that the washers that go between the suspension bracket and the bushings have a lot of lateral play over time, eventually digging into the bushings and slicing them up. A temporary fix that I added when I replaced mine was using superglue to fuse the washers and the bushings together in order to prevent the lateral play from occurring.
I do not believe that the bushings themselves are weak, because the Kaabo Wolf Warrior X uses the same materials, but none have been reported to have crumbled on anyone yet. The springs are most likely at fault, since their inner diameter is so large and they do not sit flush with the bushings. Kaabo should consider offering future 11” frame models with thicker compression springs that are similar to the ones on the Wolf Warrior X.
