It's actually torque that accelerates. Comes from F=ma at contact-patch. Rear-wheel torque is divided out by radius of wheel+tyre to generate linear-thrust F for instantaneous acceleration. HP is result of torque over time and distance. It's cause & effect, but it starts with torque first.
Also confirmed by acceleration curves, which actually matches torque curve, not HP. Notice that peak-HP occurs near redline on Ducati Monster, but acceleration curve matches torque-curve with max-acceleration occuring at torque-peak in mid-range, not HP-peak.

We see that max-acceleration in each gear occurs in mid-range RPM, not at redline.
