I bought this for a completely different purpose. I built a custom-designed tail rack for my Duke 390. The 4mm plate was the primary reason to buy this, whereas the others were all 3mm... Since it was a custom fit, we used an adapter to mount the plate. Since my brother has an xpulse I knew even if it didn't fit my requirement, I can still use it on the Xpulse... so all in all, a safe & good purchase that turned out to be a perfect fit for my requirement. Not sure if this review would help other Xpulse owners, however would give a good review for the product.
