New 2019 Suzuki RM-Z250 Detail Released

Posted:

Suzuki Motor Corporation lifted the covers off their next generation quarter-litre motocross weapon; the 2019 RM-Z250.
Suzuki Motor Corporation today has released further information regarding technical changes and updates for MY19, ensuring that the RM-Z250 will be at the top of its game for the new season.

The list of impressive changes starts with a new, more powerful engine. Featuring a newly designed cylinder head with optimised intake and exhaust port tuning, matched to a higher lift intake camshaft to achieve an approximate 5% increase in maximum output.

The fuel injection system now features two injectors. Instead of using a single injector that can compromise low-end fuelling in order to supply enough fuel for top-end power, the primary injector delivers precise low-rpm fuelling while a secondary injector at higher rpm provides the extra fuel needed.

Fuel pressure has been increased by 17% over the previous model resulting in improved throttle response.
The exhaust pipe was lengthened by 99mm, with the internal diameter tapering from Ìü35mm at the cylinder head to Ìü45mm at the muffler improving output throughout the RPM range, with bottom-end output most notably improved.

The RM-Z250‰Ûªs evolved traction management system works seamlessly with the rider to get the power to the ground. The fourth-generation system‰Ûªs engine control module (ECM) automatically adjusts ignition timing and fuel injection based on throttle position, engine speed and gear position.

Already known as one of the best-cornering motocross bikes available, but for MY19 the Suzuki engineers worked hard to make it even better.

The frame and swingarm are all new, with the aluminium frame spars changing to a hollow square section that does away with an internal rib, shedding 370 grams while increasing torsional rigidity by 10 percent for better stability and bump absorption. Using a new hydroforming process for the aluminium swingarm permits a tapered cross-section without any welding, making the new assembly just as rigid with thinner walls for a weight loss of 80 grams.

The new KYB coil spring fork replaces the previous model's PSF2 air fork. Featuring a unique design that provides a progressive damping setup offering excellent compliance over small bumps while firming up deeper into the stroke to handle bigger hits such as harsh jump landings.

Upper and lower triple clamp design has been optimised for rigidity while cutting 60 grams. Out back, the rear suspension linkage ratio has been changed to firm up short stroke movement while optimising longer suspension action for better traction, and is 14.9 grams lighter.

The fully adjustable KYB shock has an improved range of adjustment, and a spring with thinner but stronger wire (feedback from MotoGP technology) that is 370 grams lighter than before.

In order to increase the RM-Z250‰Ûªs agility, the engine position was pivoted upward at the rear engine mount by 8.5mm measured at the crankshaft centre. The upper engine mount brackets are now aluminium instead of steel, and rather than four brackets suspending the engine from a single location, the 2019 RM-Z250 has four brackets on both sides of the engine. This not only drops another 90 grams, but also increases overall rigidity.

New lighter Dirtstar wheels reduce all-important rotating mass by 40 grams up front, and 60 grams in the rear. For MY19, the RM-Z250 will be fitted with Dunlop‰Ûªs latest Geomax MX33 tyre that has received rave reviews. The front brake disc diameter has been increased from 250mm to 270mm and the brake pad material has been changed for more linear response characteristics as you brake harder.

Like the RM-Z450, the 2019 RM-Z250 is finished in the Team Suzuki off-road colours of yellow with blue accents, making the RM-Z line-up easily recognisable.
Target on-sale date in Australia will during the first quarter of 2019, with final specifications and pricing being announced closer to release.
