In this segment of the video, it is discussed how small displacement, lots of cylinders, short stroke, and low piston speed define high-revving motorcycle engines. The Drive LV8 is a special project by Ian Drysdale, combining parts from different motorcycles to create a V8 powered bike. The Honda RC 166, part of the Honda RC series, featured a small inline 6 engine and was successful in the 1966 and 1967 MotoGP seasons. The Yamaha FZR 250, part of the FZR series from the 80s, was a top-tier 250 CC Supersport bike.

In this segment of the video, key points about high-performance motorcycles are discussed. The Honda CBR 250r, known for its high revving capability, was originally thought to be sold only in Japan but was also exported to Australia. The Honda NR 500, designed for racing with innovative combustion technology, aimed to compete with two-stroke engines with a high redline and power output. The Kawasaki EXI 250 Ninja, the smallest in the Ninja series, was one of the oldest models with various iterations.

In this part of the video, the narrator discusses high-performance versions of motorcycles, such as the SP version (ZXR 250) with upgrades including a larger exhaust and high rev limit to 20,000 rpm. The Honda RC 149, dubbed the world’s first 125cc five-cylinder engine, won five out of nine races with an 8-speed gearbox and a top speed of 130 mph usable from 17,000 rpm upwards. The Honda RC 116 raced in the 50cc Grand Prix class in 1966, reaching over 22,000 rpm and introducing rim brakes that act directly on the alloy wheel.
