KIWI RIDER OCTOBER 2017 VOL.2 | Page 12

2018 Suzuki RM-Z450 launched at Taupo S uzuki launched the eagerly awaited, all-new RM-Z450 at the start of September in Taupo. Rather than make you wait another couple of weeks for our first impression of the new bike, we’ve done a quick video edit to give you something to watch while we write up the test and cut a longer video for the next issue. Check out the video across the page, and read what’s been done to the new bike on a tech front down below. ENGINE/FUEL INJECTION More power and improved throttle response come courtesy of some significant tinkering. There’s a stronger piston (bracing ribs on the underside), new inlet port shape to promote fuel mixture swirl, higher lift intake cam, new injector firing down the inlet towards the inlet valve (rather than across it), and a new airbox with larger filter inlet (which is better protected to keep the filter cleaner for longer) to give a flatter torque curve with better midrange and increased peak power. A new throttle body and a higher pressure fuel pump give better throttle response. BRAKES Up front there’s a larger diameter disc but nobody seems to know how big it is, so we’ll have to wait and see. The rear master cylinder is smaller to avoid crash damage by the look of it. STYLING Fresh styling gives the bike a more angular look than last year and is much closer to the Suzuki factory machines. With a graphics kit and a pipe it’d be almost indistinguishable from the factory bike – very trick. The bike is slimmer in the seat area which should make it easier to move around on. There’s a new muffler which looks pretty big but has been built to meet the new FIM noise regulations. The wheels get a factory-style black look and are a little lighter. There’s also an engine protector (splash guards) to shield the water pump and magneto cover. ELECTRONICS There’s a new (third generation) Electronic Control Module (ECM) for Suzuki’s traction control that’s faster at processing the incoming sensor data with more memory capacity to give better traction management. The Holeshot Assist (S-HAC) also gets an update to its A-mode (hard or slippery surfaces) giving finer throttle control to improve the rider’s feel for grip.
