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.
