Peak torque is down from 79.7 pound-feet at 9,500 rpm to 78.2 pound-feet at 9,250 rpm, but the all-important torque curve is now smoother, with a noticeable increase in the mid-to-high rpm range. (Jason Critchell/)

The small winglets are for cosmetic effect only, and Suzuki doesn’t claim any downforce or performance gains. (Jason Critchell/)

Capacity, bore and stroke, and compression are unchanged but camshafts, cam chain, and valve springs, along with a slipper clutch, are new. (Jason Critchell/)

There’s also a completely new exhaust (to meet Euro 5), along with smaller and lighter electronically controlled throttle bodies. The 40mm throttle bodies (down from 44mm) are designed to give a smoother throttle feeling. (Jason Critchell/)

The end result is an increase from 147.8 bhp at 10,000 rpm to 149.8 bhp at 11,000 rpm—not a huge step. However, the 1,000-rpm increase in the rev range adds versatility to the engine. (Jason Critchell/)

The tapered bars are now 23mm (0.9 inch) wider and 20mm (0.78 inch) closer to the rider, thus creating a more upright riding position. (Jason Critchell/)

The now larger 5-gallon fuel tank has also been reshaped to increase comfort and give a greater tank range. (Jason Critchell/)

Quoted fuel consumption is down, but the tank has increased in capacity, which means the tank range has increased overall, despite the engine being less frugal. (Jason Critchell/)

There’s no IMU to determine lean angle and therefore no lean-sensitive rider aids, so it’s conventional ABS and traction control only. (Jason Critchell/)

It may look like the old exhaust but the 4-2-1 system is completely new, redesigned to maximize performance but also conform to Euro 5. There is a new layout behind the collector and a secondary cat-converter. (Jason Critchell/)

A is Active, B is Basic, C is Comfort. Each mode offers maximum power, but changes the throttle response and torque characteristics. (Jason Critchell/)

Three color options: Glass Sparkle Black, Metallic Triton Blue, and Glass Matt Mechanical Gray, with the new “urban camo” look on all three color options. (Jason Critchell/)

Sportier rubber than previously: new Dunlop Roadsport II tires have been engineered to perform with the new GSX-S1000. (Jason Critchell/)
