Overview

Sometimes it’s called the retrograde, the analog, or even the purist. The 2023 Suzuki RM-Z450 is this workhorse that stubbornly refuses to follow the herd. While all its rivals, from KTM to Kawasaki, now feature electric starters, Suzuki persists with its old-fashioned kick. A choice that speaks volumes about its philosophy: to reduce mechanics to its simplest expression to gain reliability and lightness. At 112 kg fully fueled, it certainly holds its own against competitors who are often heavier and technologically advanced. For a little under €9400, you’re buying a race weapon here, not a gadget.

Suzuki RM-Z450

Under the 6.3-liter fuel tank beats a 449 cm3 single-cylinder engine that delivers around sixty horsepower. The raw figures don't tell the whole story. Suzuki has worked on the power curve, seeking to flatten the torque for a more linear and controllable response, a must when the track turns into a slippery toboggan. The secret lies in a whole series of revisions, from the 30% wider airbox to the intake geometry. But the real asset is its electronic brain. The S-HAC, or Holeshot Assist Control, is a clever system that adjusts the ignition at startup to optimize propulsion off the grid. Three modes allow you to adapt to concrete, dirt, or to cut them all. It's intelligent, efficient, and requires no intervention. Coupled with the third-generation traction control system, this gives a motorcycle that channels its power with surgical precision.

Where the RM-Z450 really scores points is in its handling. The chassis has been refined, with the steering stem set back 10 mm for a wheelbase of 1480 mm and a more natural front mass transfer. The twin-spar aluminum frame gains longitudinal rigidity while losing 700 grams. The result is a machine that leans with disarming, almost intuitive frankness. The Showa suspension, with its spring fork at the front and BFRC damper at the rear, makes the air fork of the previous generation a distant memory. It digests impacts without flinching and keeps the bike glued to the ground. You can feel that the lessons from Supercross and Motocross have been absorbed.

So, who rides this Suzuki? Clearly for the seasoned rider who prefers raw feel to electronic assistance, the one who isn’t afraid to give a kick in the void on a cold morning. It's a demanding machine that rewards technique and commitment. Compared to a Yamaha YZ450F or a Honda CRF450R, it may seem spartan. But that’s also its strength: it’s direct, reliable, and its price, although substantial, remains in the high end of the segment without being exorbitant. It makes no concessions, and that's what earns it its fan club. In an increasingly aseptic world, the RM-Z450 is a well-placed kick.
