2021 Suzuki RM-Z250
The 250 class in motocross doesn’t forgive the slightest weakness. That’s why we’ve designed the RM-Z250 to achieve the right balance of “Run, Turn, and Stop” necessary to win in this ultra-competitive arena. Intensive work by our engineers has once again made the RM-Z250 the leader out of the gate, with a engine featuring increased power across the board and class-leading electronics, a lighter frame and swingarm plus updated suspension for even better handling, a completely new styling design, and a laundry list of other updates to make it the most potent motocrosser in its class. Look out…the RM-Z250 is here!
Features may include:
- CLASS-LEADING ELECTRONICS
All the power in the world won’t do any good if you can’t transfer it to the ground, and Suzuki’s innovative electronics work transparently with the rider for maximum acceleration on any type of dirt or track conditions. The 2018 RM-Z450 debuted the third-generation traction management system, with a significantly updated S-HAC (Suzuki Hole shot Assist Control) and more powerful ECM (engine control module). From 2019, Suzuki’s RM-Z250 goes another step further with the fourth-generation system featuring updated ECU software.
The RM-Z250’s S-HAC monitors throttle position and gear position in order to adjust ignition timing for maximum acceleration through the three critical stages of a motocross start: the exact moment of launch, getting over the starting gate, and then powering up the start straight. Three settings are available, with A- mode intended for harder surfaces where controlling wheelspin is paramount, B- mode for normal dirt conditions with good traction, and an “off” setting.
- USE ANY LINE IN CORNERS
The RM-Z250 is already known as one of the best-cornering motocross bikes available, but we went to work improving it even more. The frame and swingarm , with the aluminum frame spars changing to a hollow square section that does away with an internal rib , are shedding 370 grams while increasing torsional rigidity by 10 percent for better stability and bump absorption. Using a hydroforming process for the aluminum swingarm permits a tapered cross-section without any welding, making the assembly just as rigid with thinner walls for a weight loss of 80grams.
In order to increase the RM-Z250’s agility, the engine position was pivoted upward at the rear engine mount by 8.5mm measured at the crankshaft center. The upper engine mount brackets are now aluminum instead of steel, and rather than four brackets suspending the engine from a single location, the RM-Z250 has four brackets on both sides of the engine. This not only drops another 90 grams, but also increases overall rigidity.
- TOP-SHELF SUSPENSION, WHEELS, TIRES
The 250 class is all about maintaining momentum. This requires handling any and all track obstacles as quickly and efficiently as possible, meaning keeping the chassis stable and providing the rider with good track feel and feedback-without pounding him into submission. Whether it’s skipping over a big set of whoops, gassing it over a nasty rut- and pothole-filled straight, or landing from that big jump, the Suzuki RM-Z250 has you covered with KYB coil spring fork and redesigned rear shock and linkage.
