Review and technical characteristics of suzuki rm 250

Model of the motocross motorcycle Suzuki RM-Z250

appeared in 2004 as a joint development of Suzuki and Kawasaki. At that time, two absolutely identical motorcycles appeared on the market, sold under different names - Kawasaki KX250F and Suzuki RM-Z250. This continued until 2006, after which both Suzuki and Kawasaki decided to abandon cooperation and continue the development of these motocross models, but separately from each other.

The Suzuki RM-Z250 subsequently became a replacement for the Suzuki RM250 and Suzuki RM125 2-stroke models.

For 2010, the RM-Z250 undergoes major changes, the main one being the replacement of the carburetor with electronic fuel injection.

From 2004 to the present, the model has been constantly changed and improved in terms of technical aspects, which affected the frame, engine and chassis.

Among the key features of the motorcycle, it is worth noting an aluminum frame, a 4-stroke liquid-cooled engine, sports adjustable suspension, disc brakes, a 5-speed gearbox and 106 kg of curb weight (for the 2022 version).

Suspensions Suzuki RM-Z250

The 2022 Suzuki RM-Z250 is equipped with a KYB Air-Oil Separate (AOS) spring fork and a KYB shock absorber with separate adjustments for smoothing fast and slow compression, fast and slow rebound, and spring preload. These are amazing suspension components, perhaps the best in their class.

But, unfortunately, when Suzuki designers chose the factory settings for these suspensions, they apparently did not think about comfort. The monoshock absorber is quite rigid, but in principle adjustable. But the fork is clearly poorly calculated: springs of 5.0 Nm in the front and 5.2 Nm in the rear are more common on heavier and more powerful 450 cc motorcycles, and there is a feeling that the stock RM-Z250 suspension would be suitable for a professional cross racer for a full-fledged supercross track... Or perhaps a fat newbie
