Suzuki pairs value, versatility, and performance in the liter-sized superbike segment with its 2021 Suzuki GSX-R1000R ($17,749). This up-spec GSX-R benefits from upgraded suspenders, a slick-shifting electronic quickshifter, and a couple of other worthwhile upgrades that make it more competent on and off track.br br --br br When it comes to outright street-riding comfort, few sportbikes ride as well as Suzuki GSX-Rs. And that trend continues with its 1000R. It’s a very slim motorcycle—especially for an inline-four. The seat is well supported and the reach to the clip-on style controls isn’t too aggressive. We like the position of the rider’s footpegs, which are neither too high, nor too low. It would be nice if this GSX-R had foot control adjustment like its GSX-R600 and 750 duo. One change we bemoan is its 0.4-gallon-smaller 4.2-gallon fuel tank.br br Tap the starter button and the GSX-R fires to life with a unique growl. Despite employing a conventional inline-four firing order, the engine offers signature character unlike others in its class. We especially appreciate its meaty intake roar and whiny, high-tech-sounding exhaust note. Suzuki offers an ingenious variable valve timing solution that helps give its four-cylinder the best of both worlds.
