This is not new and I've been using it for awhile now for top end rebuilds. I just completed a full top down GasGas 250 rebuild on my buddy's bike and figured I'd bring it up. In case you guys haven't seen this it allows super easy wrist pin clip installs with no trauma to the clip. Note it will not work with the "easy clip" type clips that come with the 300RR Vertex. I'm not sure what the 250RR Vertex has but the TM/GG part still comes with the C clips.
