* Suzuki RMX 250 S
The first generation of the model, 1989-1990, featured a conventional fork and a maximum engine output of 37 hp. The engine was equipped with a balance shaft and power valves that altered the intake and exhaust sections for smoother thrust and optimized engine performance over the entire rev range. Foreign sources call this generation of the motorcycle - "MK1" ".
By March 1991, Honda introduced a new generation of Honda CRM250, dubbed MK2 by consumers. Instead of the usual 41 mm telescopic fork, the model gets an inverted fork with a 45 mm blade diameter and is adjustable. The rear shock absorber increases its travel from 280 mm to 300 mm. The frame structure is reinforced by thickening the tubes. The engine is equipped with a new PGM-RC power valve system that digitally controls the exhaust flow, depending on the engine speed. In addition, the model gets a new exhaust, an improved combustion chamber and an intake system - all changes were aimed at improving the performance of the engine in the low and mid-range zone. From this generation onwards, the maximum power is increased to 40 hp and the torque is increased from 33 to 36 Nm at the same operating speed. New, more advanced ignition system - PGM-DC-CDI. The compression ratio of the engine is increased - from 6.2 to 6.4.
