The Suzuki RM250 and RM125 share a similar chassis configuration, and have similar updated features in this area on the 2004 models.

A completely new rear shock linkage system giving more progressive rear shock action is featured on both bikes.

The RM250 benefits from new Showa twin-chamber cartridge-type front forks and new Showa piggyback-reservoir rear suspension for excellent shock absorption and feel.

The front fork offset of the RM250 has been changed from 24.5mm to 22.5mm for improved cornering performance.

Significant upgrades to the brake packages of both Suzuki off-roaders include a new floating disc brake system and a new front brake master cylinder for more controllable stopping power.

Other changes include a redesigned rear brake master cylinder and a larger  rear brake pad retainer for less brake drag.

For 2004, the RM250 and RM125 will also have a thicker rear wheel rim for greater durability.

Both motocross machines also have an updated shift cam stopper for a smoother gear shifting feel, while an improved riding position provides greater freedom of weight transfer.

A redesigned fuel tank prevents fuel from floating backwards, while revised fuel tank mounting bolts allow for easier maintenance.

Suzuki RM250 - Engine

Suzuki has also made improvements to the powerplant of its World Championship-winning RM250.

It has a reduced squish height and redesigned cylinder head for improved throttle response at low-to-mid rpm range, and wider, longer sub-exhaust posts for excellent power feel at mid-to-high rpm range.

Redesigned control cams of the sub-exhaust port valves provide a seamless, controllable powerband, and new barrel-type piston rings reduce friction for improved throttle response.

A new clutch lever adjuster allows the clutch to be adjusted when riding while the frame reinforcement of the RM250 has been thickened from 1.4mm to 1.6mm for improved straight-line stability.

The 'K3' RM250 is due to arrive in July, 2003.
