2019 Suzuki RM-Z250 Dirt Bike Review Specs

The 2019 Suzuki RM-Z250 Dirt Bike is one of the best and highly impressive Suzuki bikes that offers remarkable riding pleasure of all times. This dirt bike is redesigned to achieve all the battles due to its sleek and race-ready appearance and fully upgraded engine. There is a list of changes in the bike that helped in achieving superior performance. The Suzuki engineers have used the Run, Turn and Stop philosophy to make the bike best of all times. The RM-Z250 has a great history when it comes to the best handling experience. This 2019 model has higher power and has a lot of changes that include the new cylinder head and an all-new dual injector EFI than boost the overall performance through the entire rev range.

The frame and swingarm are entirely new and features the KYB-supplied suspension that features the new coil-spring fork. The reliable brakes with fully ergonomically shaped bodywork help in keeping the rider in full control as the RM-Z50 carves up the race track. The new EFI system provides the maximum performance, thanks to Suzuki’s proven fuel coupler system. The Suzuki’s Winning Balance is again on display with 2019 RM-Z250 as it again raises its high standard for cornering performance.

2019 Suzuki RM-Z250 Dirt Bike – Features and Price

Engine Features

The 2019 RM-Z250 features the robust and high performing 249cc fuel-injected, liquid-cooled, four-valve, DOHC, four-cylinder engine. The engine has an all-new cylinder head giving the best and reliable performance of all times. The improvements in the driver provide a higher power output with better throttle response throughout the entire rev range. An all-new cylinder head contains the new intake port shape and unique finishing that finely-tubes the fuel and air change into the bike’s combustion chamber. About 30% of the large air cleaner opening is combined with the direct air cleaner outlet tube path into the throttle body for better airflow.

An updated fuel injection system contains and extra-smooth power delivery and high fuel efficiency with ultimate reliability and natural tuning capability. The Suzuki engineers have used twin fuel injectors for the first time in their MX models. The fuel/ air mixture created by injectors improves the charging efficiency, and it also increases high RPM power. The new primary fuel injector is at the bottom of the throttle body, and it sprays fuel at the butterfly valve that helps in improving fuel and air atomization. The secondary nozzle is positioned in the air cleaner inlet duct to that the fuel and air can have more time to mix and cool before entering the engine.

The Suzuki RM-Z250 has a high capacity fuel pump that gives 17% more output thanks to the new twin-injector system, and it mixes the fuel and air charge to enhance throttle response. The throttle bodies eliminate complex control linkage so that the rider feels the more direct connection — an all-new intake camshaft profile with more valve lift and improving power at entire engine speeds. The latest cam chain tension adjuster and guide have been entirely redesigned to reduce the mechanical loss due to friction. An all-new aluminum cylinder is finished with Suzuki Composite Electrochemical Material (SCEM) coating for reliable and efficient heat transfer.

Furthermore, the machining process at the piston pin holes is changed to reduce stress at the piston crown and increase reliability. The engine starting remains simple due to the kick-starter and fully automatic decompression system that works accurately and efficiently.

The use of a high-flow exhaust system ensures the more extended head-pipe tapered mid-section and multi-layer silencer that provides better flow for the entire rev range with an emphasis on low-rpm performance. The new exhaust silencer features the four-layer design that improves the performance and maintains compliance with AMA sound regulations. The new resin engine protectors help guard the coolant pump and the stater cover from debris and stones.

Advanced Electronics

Suzuki’s proven and easy-to-use fuel couplers include the simplification of EFI tuning. It helps in quick fuel adjustments that suit riding conditions while the two couplers are provided. One of the richer-than-stock and another for leaner-than-stock fuel setting. The rider can also change fuel settings in seconds by merely connecting either coupler to the wire harness. The 2019 RM-Z250 contains an evolved, better, and faster traction management system. This Electronic Control Module (ECM) consistently monitors the throttle opening, engine speed, and gear position by adjusting ignition timing and fuel injector duration to the fine-tune engine output.

The traction management system of RM-Z250 is slightly different from the older 2018 Suzuki RM-Z250 Dirt Bike as it does not measure rear tire spin. The Suzuki-Holeshot Assist Control (S-HAC) is a new selectable launch system that has been derived from a factory race bike. There are three different S-HAC modes for riders, and rider can easily choose the best option as per the rider skill level and starting conditions. These modes are A-Mode, B-Mode, and Base Mode.

Transmission and Drive Features

The new five-speed communications are updated with the original second gear ratio. It features an overall final rate that matches the engine’s stronger output for better acceleration and top speed. The gear shifting operation is smoother and precise that gives exact Suzuki transmission standards. This bike features the carefully designed parts like the precisely machined shift cam and corresponding gears that create a transmission a racer can rely on. The multi-plate, wet-clutch features the rack-and-pinion clutch release mechanism for an accurate feel of the engagement and disengagement points while riding. The new lighter-weight chain guide is carefully shaped to route the drive chain smoothly accurately.

Chassis Features

The Chassis of 2019 RM-Z250 Dirt Bike comes with the new frame and swingarm design that features the Suzuki’s reputation for creating the best-handling motocross bike. An aluminum alloy with a twin-spar shell combines with the cast and extruded sections to achieve superior front and rear weight distribution while balancing strength and weight. This new frame is about 370 grams lighter but has a 10 percent increase in torsional rigidity. The position of the engine is slightly changed so that the crankshaft sits higher in the chassis for nimble handling characteristics.

The design of the rear upper engine has been updated to the pair of mounts which are outboard of its cylinder head to increase overall strength, plus it allows us to have a direct intake path. The engine mount material is now changed to aluminum from steel to reduce weight. An all-new swingarm is shaped by using an innovative hydroforming process that maintains strength, but it reduces weight by 0.6 pounds. An all-new hydroforming process enables engineers to create the tapered swingarm beam that not only increases the overall rigidity, but it reduces heavier welding.

The hexagonal aluminum rails have been used on the sub-frame for lighter weight and slimmer appearance. The sub-frame rails are moved inward to further slim the bodywork, but they are raised to offer additional space for its giant air cleaner. The new sub-frame and the entire body are kept slim so that the rider can move freely on the seat, especially during spirited riding. The latest KYB supplied shock absorber has thin-wire spring, spring guide, and cushion rubber guide and lower link that weighs less and provides better movement reaction. The new spring and ring weigh 447.5 grams, less than the prior parts. The KYB shock features the new damping force circuit and different levels of rear lever ratios for better suspension traction characteristics. The damping force adjuster has a more extensive tuning range, so the settings can better match the conditions and rider’s style.

An all-new Renthal aluminum tapered handlebar features the straighter bend than prior models that help aid the rider during aggressive maneuvering. The new lighter upper fork bracket is being used with the latest front suspension and handlebars. The braking system comprises up of a more massive 270mm of wave-style front brake rotor along with the Nissin two-piston brake calipers. The material of brake pad is also changed to enhance the performance, plus an all-new front brake lever is the push rod type that effectively transmits the squeezing force. The new design rear brake master cylinder hugs the frame beam for low dirt contamination. The wheel features black anodized D.I.D Dirt Star rims for new cross-section design that maintains strength while reducing un-sprung weight. The wheels are fitted with the racetrack-developed Dunlop Geomax MX33. The rear tire is nearly half-pound lighter than the tire being used in the previous model.
