摘要

Why does a rider buy this 600cc sportbike rather than that one? A few people read the specs and decide that way, but many more assume all the specs are pretty much the same and go for the raddest and baddest look. Yamaha is covering both bets with the 2006 YZF-R6, which looks like a sinister cross between Samurai armor and 21st-century motorcycle tech. Specs first: All Yamaha would say at this early date is that "red-line is 17,500 rpm." If we subtract 2000 revs to estimated peak-power rpm, we get 15,500. Take that number, the displacement and current-level combustic pressure and crank it through the formula and we get just under 140 crankshaft horsepower. Oh, one other loose fact: the induction system has a "computer-managed throttle butterfly." This tells us that the new R6 probably has a dual butterfly system. One in each intake pipe is controlled by the rider, while the computer modulates the opening of the second one just enough to let the fuel keep up with the air. This is useful when the intake tract is so huge (as probably is the case in a 17,500-rpm engine) that it won't work any other way.
