This time it's Maniac Level 5, so we've gone into a lot of detail! In recent years, 250cc four-cylinder bikes such as the Honda CBR250RR and Kawasaki ZX-25R have become popular, but in the mid-1980s, the Yamaha Feather 250, Kawasaki Barrios and ZXR 250, and Honda's CBR 250 were very popular!　But about 60 years ago there was already a 250cc six-cylinder motorbike (racer). The Honda RC166 was such a dream bike. In this issue, we hear the secrets of the efforts and ingenuity of the designers and machining engineers who made the RC166's engine a reality. We also explained the contents of the engine using documents that have never been shown to the public before.
