On the road, the difference in acceleration between the two bikes feels even more dramatic than the dyno figures suggest. The second-generation bike absolutely walks away from the old bird in any gear or riding situation, whether from a dead stop or rolling on. Initially, this was confusing: Despite the 16-horse difference in peak power, the dyno charts for the '07 and '08 bike are virtually indistinguishable up to 8250 rpm, with essentially equal low- and midrange power. What's more, the '08 bike tips the scales at a shocking 29 pounds more than the '07 model, mostly due to the new, Euro 3-compliant exhaust. Looking at the numbers alone, the new bike should feel slower on the street; instead, the old bike feels like it's tied to a post. What gives?
The answer is revealed after you juggle the parameters of the dyno readout. Graphing horsepower against time instead of rpm shows that the '08 bike arrives at 8000 rpm more than a second quicker than the '07 bike--so it gets to the meat of its power more quickly. Suzuki's extreme efforts to make the new motor rev quicker pay big dividends on the street. These internal engine changes, along with slightly shorter gearing (now 18/43 for an overall ratio of 2.39, compared to 17/40 for 2.35 in '07), let the new bike spool up faster, giving the perception of more power.
