Raptor is a family of methane/liquid oxygen rocket engines under development by SpaceX since the late 2000s, [2] although LH2/LOX propellant mix was originally under study when the Raptor concept development work began in 2009. [15] When first mentioned by SpaceX in 2009, the term "Raptor" was applied exclusively to an upper stage engine ...
SRAM is an example of a recent trend within the high-end cycle-component segment of the bicycle industry, where companies seek a position as a "one-stop shopping center" for bicycle frame manufacturers/bicycle brand owners, supplying all or most of the parts needed to build a complete bike.
The first bike manufactured by Yamaha was actually a copy of the German DKW RT 125; it had an air-cooled, two-stroke, single cylinder 125 cc engine [1] YC-1 (1956) was the second bike manufactured by Yamaha; it was a 175 cc single cylinder two-stroke.
