2018 Suzuki RM-Z250

While the RM-Z450 has undergone a full engineering redo for 2018, little brother RM-Z250 carries on with minimal changes, including revised graphics, a gripper seat, and a new top-mounted shock damping adjuster. Although both bikes are yellow, black, and blue, in key areas they are as different as chalk and cheese. The RM-Z250’s 249cc DOHC engine has an ultra-high 13.75:1 compression ratio, which helps the quarter-liter motor kick out competitive torque and horsepower. And the suspension comprises the now several-years-old “pneumatic” (air spring) KYB fork and coil-spring shock.

Largely due to its lighter engine and related componentry, the RM-Z250 weighs a claimed 234 pounds wet, a bit chunky for the 250 class. Fortunately, although it’s now a step behind in development, the smaller RM-Z is still a delight to ride, possessing both the nimble handling and meaty midrange that have long defined the model. In short, the RM-Z250 is easy to ride—and easy-to-ride bikes help riders go faster. Bonus features absent on some 250s include selectable launch control, quick-change fuel-mixture couplers (rich, stock, and lean) to fine-tune the engine for conditions, and stylish black anodized steering clamps.

Likes: Grunty for a 250, quick-handling, and easy to ride.

Dislikes: Motocross technology has leapt ahead of this RM-Z model.

Verdict: Whether you're into training, trackdays, or racing, the RM-Z250 can do it all.
