Suzuki Acts On Impulse
SUZUKI ACTS ON IMPULSE
SUZUKI HAS STEPPED into Japan's highly popular "naked" class with a vengeance, introducing the Impulse 400.
Suzuki had the advantage of studying the competition before unveiling the Impulse, and its advertising suggests that scrutiny paid off. Suzuki calls the Impulse, at current exchange rates costing about $5500, “The Strongest Naked.”
The 399cc engine is based on the liquid-cooled GSX-R400 powerplant, but has a slightly longer stroke. Power is plentiful in the 5000-to-7000-rpm range. The Impulse is restricted to around 50 horsepower, per Japanese law, but Suzuki designed the engine so that a little “tuning” will provide about 20 more horsepower.
As is standard on the nakeds, the Impulse is styled to recall bikes of the 1970s and early ’80s, with twin rear shocks, and a tube frame. The frame and suspension are both stiff, since the Impulse was designed with racing in mind.
Although the handlebar is a little high, the Impulse takes to tight comers in sportbike style. Ground clearance and cornering stability are both abundant; just turn in and trace the line. Highway cmising and around-town riding is pleasant as well, thanks to the smooth engine and comfortable riding position.
Introduction of the Impulse adds not just another choice for street riders, but also for those who compete in Japan’s “naked” racing, which is drawing great numbers of riders. The field, at least in the 400 class, is set. Competition for sales should be as intense as the race for trophies. Yasushi Ichikawa
