The RM-Z450 isn’t road legal – it is a purpose-built dirt bike that is intended for use solely as a recreational tool and to hone dirt riding skills. As such, the company does not release power and torque figures, preferring to say instead that it is ‘accessible and suitable for its nature’. What they will let us know, though, is that it is a 449cc single-cylinder fuel-injected DOHC water-cooled engine, that it weighs 112kg, and that it has 330mm of ground clearance. The frame, swingarm and suspension are all optimised for the application. It is available only in yellow, and since it isn’t road legal, don’t expect ‘accessories’ like a headlamp, turn indicators or a horn. Wheels are standard-for-dirt sizes – 21 inches in front and 18 inches at the rear. The tyres are dirt tyres.
The RM-Z450 competes directly with the Kawasaki KX-450F.
