Actorânetwork theory (ANT) is an approach to social theory and research, originating in the field of science studies, which treats objects as part of social networks.s the term implies, the actor-network is the central concept in ANT.

The new aircraft, designated the F4U-4, put up monstrous performance numbers. With a top speed exceeding 450 mph at level flight at altitude she was one of the fastest propeller-driven fighters of the war.
IIRC the Yamaha FZ400 had a redline of 14,000 rpm and was quite fast. ISTR that the two-stroke RD400 (?) also had a high redline and was fast for its time. I believe the FZ400 is about 10 mph faster than my 600 cc Seca II. My YZF-R1 has a 1 litre engine that makes 142 hp. Two years later they got 180 hp out of the same displacement. 50cc and 125cc are beginner learner bikes that can only do 30mph and about 60mph respectively. 250cc up to 400cc are lightweight bikes you have to rev hard or change gear regularly to maintain momentum but can easily do 70mph.
