For instance, an example catalogue extract for a motorcycle reads-
Bore / stroke : 102,5 mm x 76 mm. Capacity : 1,254 ccm. Rated output : 100 kW (136 PS) at 7,750 U/min. Max. torque : 143 Nm at 6,250 U/min. Compression ratio : 12,5 : 1.
From a user's point of view, surely they are more interested in how much forward thrust the vehicle can provide, as opposed to the torque at the rear wheel (which is also implementation dependent). Thrust is also more easily relatable to other parameters of interest, such as acceleration (assuming a known mass).
From a quick check, aircraft engines are specified in terms of thrust, and not torque. So why not for bikes and cars? Interested to hear different points of view.
