To the OP, make sure you find out from the rearset manufacturer the possible peg positions relative to the OEM rearsets. Having owned many bikes and almost all with aftermarket rearsets of one brand or another, in my experience many of them are designed to replicate the OEM position in their most forward and lowest position. The other positions are either higher-up, further-back, or both as that is most commonly needed for racing, where this part category originated.
If you want a further forward and lower position than the OEM, you need to verify that was in the design brief of the product you are considering. Good luck and report back here so other like-minded individuals will be able to benefit from your research.
