P122 CN III IN THE PADDOCK BY MICHAEL SCOTT T he British GP was a great race, and fascinating at a deeper level as well as the raw excitement of a battle won by inches at the last gasp— fourth-closest margin in the his- tory of racing. That a (relatively) slow bike like the Suzuki, ridden by a (rela- tively) inexperienced MotoGP rider like Alex Rins could beat the great maestro Marquez on his all-conquering Honda was almost entirely unexpected. And yet, to some faceless keyboard commentators waffling on the interweb, in spite of no more engineering or mathemati- cal training than an earwig, it was easily explicable. Apparently, it is because of the engine architecture. Like this. The in-line Suzuki engine has a longer crankshaft (actually wider, in terms of how it sits in the motorcycle); the V4 Honda's crank is shorter. This width apparently makes all the differ- ence, even though they probably weigh more or less the same and are spinning at the same sort of speed and in the same direction (backward, opposite to the wheels). The 20,000-plus rpm reverse spin clearly has some effect NEVER MIND THE MARGINS, FEEL THE WIDTH How did Alex Rins beat the master, Marc Marquez, at Silverstoe? PHOTO: GOLD & GOOSE
