I doubt a small change in the linkage arm with make much difference in the linkage curve. However, changing the angle of the swingarm relative to the ground by lowering the frame will certainly reduce the anti-squat force, everything else being equal. That's like putting a lighter spring on the shock but you only feel the affect during acceleration. In addition, the lower anti-squat condition will add to the already lower rear end during acceleration giving the chassis a bit more dynamic rake and trail. During braking the bike should pitch forward a bit less thanks to the lower CG and the reduced anti-squat. However, traction might suffer somewhat. In general, the effect of changes to anti-squat are felt most in larger displacement bikes in good traction conditions where acceleration is higher.
