Overview

The Suzuki RMX 450Z is an enduro bike produced from 2017 to 2018. The 2018 model uses a liquid-cooled, 449 cm³ single-cylinder four-stroke engine with fuel injection, producing 45 hp (33 kW); its wet weight is 123.5 kg.

Its 950 mm seat and 320 mm ground clearance suit off-road riding, though the seat height can make it harder for shorter riders to reach the ground. The 123.5 kg wet weight helps when maneuvering on trails, and adjustable front damping plus rear spring preload and damping let riders tune the suspension. Electric and kick starting provide two ways to start the engine, while the 6.2 L tank carries a modest amount of fuel.

Pros and cons

Advantages

Adjustable suspension
Adjustable front damping and rear preload and damping allow the suspension to be set for different trail conditions and rider preferences.
Two starting options
Electric and kick starting provide a backup if one method is unavailable.
Manageable wet weight
At 123.5 kg wet, the bike is easier to maneuver on trails than a heavier machine.

Things to consider

Tall seat
The 950 mm seat can make it difficult for shorter riders to plant their feet when stopped.
Small fuel tank
The 6.2 L tank means carrying less fuel between refills.
