Overview

In 2012, one might have thought that Suzuki had fallen asleep at the handlebars of its RM-Z450. The competition, Yamaha, Honda, or KTM, was already fine-tuning its weapons for the upcoming season, while at Hamamatsu, they seemed content with a simple makeover of the graphics and a slight boost of the compression ratio to 12.5:1. A lack of evolution that speaks volumes, either about a guilty indifference or an absolute confidence in a winning recipe. And it must be admitted that this motorcycle, forged in the hell of the AMA championship by riders like Dungey, had compelling arguments, or rather a lack of weight, with its 113 kg ready to fight.

Suzuki RM-Z450

The heart of the beast, this 449 cm3 Keihin-injected single-cylinder engine, remains a benchmark in terms of character. It does not seek hysterical peak power, but prioritizes phenomenal torque and a progressiveness that transforms the track into a playground. Power arrives smoothly, predictably, which inspires incredible confidence, especially for the amateur rider who prefers regularity to surprise. The five-speed gearbox, supple and precise, is the perfect tool to exploit this elasticity. It is far from the excessively nervous machines; here, mastery is paramount.

This philosophy is reflected in its chassis. The aluminum double cradle frame is remarkably narrow, allowing you to weave between the knees with disconcerting ease. Combined with the reworked Showa suspension, the whole offers stability in a straight line and agility in the technical sections that remains today a lesson in balance. It is a motorcycle that forgives, that communicates, and that always seems to work with its rider, not against him. A rare feeling on a machine of this caliber.

But here is where the problem lies, and a significant one. As the market evolves, the **Suzuki RM-Z450 is the only 450 motocross motorcycle not equipped as standard with an electric starter.** In 2012, one could still let it slide, but with hindsight, this absence becomes a real issue, especially for those who stall in the middle of a technical climb. The kick becomes suddenly very heavy. The other Achilles' heel is its small 6.2-liter tank, which imposes strict management in long races or intensive training.

So, who is the rider of this RM-Z450? Certainly not the beginner, frightened by the kick and the liveliness of a 450. It is the ideal weapon for the experienced cross rider, perhaps even a veteran, who is looking above all for a readable, reliable, and incredibly well-balanced motorcycle. A precise work tool rather than a show pony. For a **price of the Suzuki RM-Z450** of around 8200 euros at the time, it offered a competitive package, but this risky technological choice of manual starting already placed it out of step. A superb machine, yes, but one that was already living with one foot in the past.
