Suzuki RM-Z250 2019 is here

Suzuki has released the full details of the new RM-Z250 which has been heavily upgrading and has a bunch of new features to set this on its way to the top from the current model, including a brand-new chassis and an uprated engine.

Following close behind its big brother the Suzuki RM-Z450, the MX2 machine gets improved rigidity with a new frame, swingarm, sharpened handling from a new rear shock and updated forks which have been dramatically improved. 

The Frame benefits from a massive weight reduction which was the main aim of the game with a new and improved frame design. Suzuki’s engineers have managed to reduce this by 370g off the previous frame from last years frame, while also increasing torsional rigidity by 10%.

The improvements are also found with the new hydroformed swingarm, which can be found with a tapered cross-section to retain rigidity despite weighing in at 80g less than the outgoing version.

Changes have been made to the pegs, bars and seat which adjust the rider’s position on the bike freeing them up for them freestyle stuns and moves on and off the track.

The changes to the RM-Z250’s engine has significantly improved to increase power across the rev range, with airflow improvements by using a new cylinder head, intake and exhaust ports and a 30% larger air filter aperture. 

A second injector has been added by the airbox for improved fuel/air mixture, where the main injector in the throttle body is angled upwards to hit the butterfly valve directly. As such, there is now improved Fuel and throttle response throughout the rev range.

The Suspension has been supplied by KYB with a fully adjustable suspension set up to the front and rear. The air forks on the current message have seen new springs and a MotoGP-derived thin wire diameter spring on the rear shock with an added saving of 370g.

The upgrades continue of with big brakes and added stopping power to the all new RM, Thanks to a new front brake with a bigger disc, the front disc changes from a 250mm to a 270mm while new pads to help rider feel. The revised rear brake master cylinder will improve operation but also prevent dirt from making its way into the system.  

Turning and handling are enhanced courtesy of a lighter set of rims, with a new front rim which is 40g lighter and 60g saved with a new rear rim. The Suzuki RM-Z250 is also provided with bigger tyres courtesy of new Dunlop MX33 to improve feel and grip.

Suzuki Holeshot Assist Control (S-HAC) gives the rider two modes which either advance or slow ignition timing to get off the line quicker depending on the surface.

S-HAC deactivates and ignition is returned to normal timing after around six seconds when the rider shifts into fourth gear or when the throttle is closed.

The traction control system differs to a road version in that it ignores rear wheel spin. The ECU monitors throttle position, engine speed and gear position and uses the information to adjust the ignition timing and fuel injection rate for maximum traction. ECU updates and the adoption of twin injectors on the 2019 model will mean improved traction control overall.
