Do you bring to mind your first bike? Was it fast, nippy, perceptive and a joy to ride? I'll bet it was a 2 tend.

Castrol R is an oil, former some in use in motorial sport circles, chiefly in the intoxicating 60's and 70's. A two-stroke oil, unmoving in use in such as unremarkable things as lawnmowers, it was distinctive by its smell; an hard perfume - quondam smelled, ne'er disregarded.

It was utilized in athletics two manoeuvre motorial cycles of those days; Kenny Roberts, Barry Sheene, Phil Read and ad infinitum. Two strokes subordinate the world, because they were machines of hurricane lantern weight (no hefty camshafts or flywheels) and split second supremacy - maximum riders would label 'power bands' that could be likened to flicking a switch on and off: ticking over, nothing; valve open, wham! Closing the throttle valve was like-minded switch a fluffy off - everything fades until that clout trimming was reached once again. Four strokes were at a disadvantage; heavy, mechanically much complex, and dragging to achieve that wizard sway trimming. In the cut and throw worldwide of racing, weight was the loser; lone alien machines, specified as the 4-stroke Honda 4's and 6's of Hailwood fame, or the fantastically-prepared and improved MV Augustas, were a clash for the 'strokers' - and this because of the stellar hurtle the engines upset at - 15,000RPM was the touchstone for the small Hondas..

Technology advanced, 4 maneuver machines became deep contenders, assisted by sport rules that killed off the strokers - crash pollution, gas pollution, all frowned upon. But up to that point, it was a two play global.
