Suzuki announces details of 2018 RM-Z450

With all-new chassis, plenty of engine updates and new styling

SUZUKI HAS just revealed the details of its comprehensively updated 2018 RM-Z450, which gets an all-new chassis, a more powerful engine with updated launch and traction control, plus new styling.

The 2018 RM-Z450’s chassis is all-new and Suzuki says the frame is 700g lighter and offers improved cornering performance, stability and shock absrobtion with optimised rigidity. The swingarm is also new and a claimed 100g lighter, while the subframe has a new hexagonal structure to make it slimmer and more rigid.

Chassis dimension changes include 15mm reduction in wheelbase (down to 1480mm), the headstock moving 10mm backwards and Renthal bars moving forward by 7mm.

As on the previous model, front suspension is taken care of by Showa, with new, wider coil spring forks instead of the air forks on the old model.

Suzuki says the RM-Z’s 449cc four-stroke liquid-cooled DOHC engine delivers more claimed peak power and low-end torque plus improved throttle response. Engine work includes smoother porting in the head, a 30% larger air filter aperture, new intake cam profile for greater valve lift, plus a new piston design, new fuel pump, throttle body and injector.

The new engine is accompanied by the latest version of Suzuki’s holeshot assist to help with launching from the gate, and traction management system. Both systems work by adjusting ignition timing and the traction system also monitors throttle position, engine speed and gear position.

Styling-wise, the new RM-Z450 gets new, more aggressive bodywork for a sharper look.

The bike should be available in dealers by the autumn and there’s been no announcement about price yet.
