EDITORS NOTE: NO TECHNICAL INFO WAS RELEASED TODAY FOR THE RM-Z250

Continued editor’s notes: Just based off a quick peak, it’s obvious that the new RM-Z250 attains a similar chassis and swingarm that the RM-Z450 snagged last year. This includes all the same bodywork and visual package. Outside of that, it continues on with KYB suspension, going from the PSF2 air fork over to a AOS spring fork, still set at 48mm for the stanchion tubes. The shock is still a traditional lay-out from KYB, unlike the BFRC on their 450, but is technically new due to the change in shock reservoir offset for the new frame. From our best guess, the engine seems to retain retain the same basic castings as the prior generation, although there’s been a change for the engine mount point and we’ve heard there are some internal changes. Beyond that, it’s easy to spot the new exhaust system. As mentioned in the pr info above, we will receive full technical details sometime in September.


2019 Suzuki RM-Z450

With a decade’s worth of race win dominance, the 2019 RM-Z450 remains the champion’s choice. Fully-revised in 2018, the RM-Z450 returns with its sleek appearance, strong engine and a nimble chassis that continues Suzuki’s tradition of having the best handling 450. To further improve the agile RM-Z450, its suspension has been refined with a new spring that is fitted to the SHOWA BFRC shock with new damping force settings while the coil-spring fork has new damping-force settings as well. Continual improvement is why the RM-Z450 remains the class standard for cornering performance.

The 2019 RM-Z450 remains the champion’s choice, as its sleek, race-ready appearance, strong engine, and nimble chassis continue the Suzuki tradition of extraordinarily precise handling. The RM-Z450 epitomizes Suzuki’s winning balance philosophy with strong brakes for controlled stopping power, a wide spread of engine muscle with high peak power, and a strong, light, and more nimble chassis that remains the class standard for cornering performance.

2019 Suzuki RM-Z450 / FEATURES

ADVANCED ELECTRONICS

The 2019 RM-Z450 features an evolved and efficient traction management system. The Electronic Control Module (ECM) continually measures throttle opening, engine speed, and gear position and then adjusts the ignition timing and fuel injector duration to fine-tune the engine output to deliver the best traction for the riding conditions. The RM-Z450’s traction management system is different from a street bike traction control system, as it does not measure rear tire spin. Because the needs of a motocrosser are different than a street bike, this system offers constant adjustment that maximizes traction at all times.

The Suzuki Holeshot Assist Control (S-HAC) is a selectable launch system derived from the factory race bike to help riders’ takeoff from the starting gate for an early lead. There are three launch modes riders can choose for the best option per their skill level and starting conditions. There are also three stages to Mode A and Mode B of the S-HAC system. This helps riders at the moment of launch, when crossing the gate, and through acceleration to the full speed. The S-HAC settings for Mode A on the RM-Z450 are specially tuned to aid the rider’s throttle control during launches.

Mode A: For hard surfaces or slippery conditions at the starting gate. In this mode, S-HAC alters ignition timing at the moment of launch and the ride over the gate to reduce wheel slip to deliver a smooth takeoff. It also advances ignition timing during this sequence for stronger acceleration. After six seconds or when you reach fourth gear, the system shuts off and returns to normal ignition timing.

Benefit of Mode A: For novice riders, and/or hard and slippery traction conditions, use Mode A for a more controlled launch.

Mode B: When conditions at the starting gate have better traction, and a more aggressive launch is desired. S-HAC will advance the ignition timing to allow increased throttle response and stronger acceleration off the line. The ignition timing alternation is in a similar sequence as Mode A, but with increased overall timing. The system will return the ignition to normal operation in three situations (whichever happens  rst): After six seconds, when you reach fourth gear, or when the throttle is closed. The system then shuts off and returns to normal ignition timing.

Benefit of Mode B: For skilled riders, and/or good starting conditions, use Mode B for a more aggressive launch.

  • Base Mode: Standard power launch, no action required on the S-HAC switch.
  • Designed for motocross use, the lightweight, battery-less, electronic fuel injection system is key to the engine’s efficient power delivery.
  • Easy-to-use fuel couplers are included to simplify EFI tuning.

For quick fuel adjustments to suit riding conditions, two couplers are provided. By plugging in either of two additional fuel-setting couplers to the wire harness, riders can opt for a richer-than-stock or leaner-than-stock fuel setting.

CHASSIS FEATURES

  • The RM-Z450’s twin-spar frame and twin-beam swingarm design continues
  • Suzuki’s tradition of delivering the best-handling motocross machines available.
  • This aluminum alloy, twin-spar frame combines cast and extruded sections to achieve superior front-and-rear weight distribution while balancing strength and weight.
  • The frame is 700 grams (1.32 pounds) lighter than the prior generation RM-Z450 to improve cornering performance and shock absorption while delivering stable handling.
  • The swingarm is assembled with thin, yet strong, materials for improved cornering performance and stable handling.
  • The short wheelbase and frame head pipe location produces quick and nimble handling characteristics.
  • Hexagonal aluminum rails are used on the sub-frame for light weight, a slimmer appearance, and easier air  lter service.
  • The sub-frame rails route inward to slim the bodywork, but also route upwards to provide additional space for the large air cleaner and the advanced BFRC shock absorber.
  • Like the trim sub-frame, all of the bodywork is slim to enable the RM-Z450 rider to move freely in the cockpit, especially during spirited riding.
  • Inspired by the advanced suspension from the GSX-R1000R Superbike, the RM-Z450 is fitted with a Showa BFRC shock absorber.
  • The BFRC uses a separate, external damping circuit that improves the responsiveness of damping force to deliver excellent traction and better absorption over bumps.
  • The fully adjustable BFRC controls damping so well during minute suspension movements that ride comfort is increased at lower speeds, while stability is enhanced at higher speeds.
  • The 2019 RM-Z450’s BFRC shock has a new spring rate and corresponding damping force settings to produce even better handling characteristics.
  • The new generation Showa coil spring front fork has large inner tubes and rod pipes for strength and durability.
  • Springs in each fork leg combine with large, adjustable damping cylinders to deliver better response to the terrain and provide a strong feeling of control to the rider.
  • Front suspension tuning and maintenance is balanced and easy: a great benefit during frequent riding. New compression damping force settings for the fork also contribute to improved handling on the 2019 RM-Z450.
  • The strong Renthal aluminum tapered handlebar has a straighter bend than prior models to help aid the rider during aggressive maneuvering.
  • The light upper fork bracket was developed to complement the Showa coil spring front suspension and handlebars.
  • For effective stopping performance and feel, a large 270mm, wave-style front brake rotor with twin piston caliper are used.
  • The trim rear brake master cylinder hugs the frame beam to reduce dirt contamination and the chance of the rider’s boot touching it during riding.
  • To support the strong engine, braking, and handling performance of the RM-Z450, the bike is fitted with racetrack-developed Bridgestone Battlecross X30 tires.
  • The wheels feature black anodized rims with a cross-section design that maintains strength while reducing un-sprung weight.
  • Suzuki beak-inspired styling has a sharper front fender and radiator shrouds blending into side covers and an upswept tail, to promote the impression of speed while reducing weight and easing service.
  • The functional styling and the motorcycle’s trim chassis permit a variety of rider positions that facilitate control and comfort.
  • The plastic fuel tank weighs a half-pound less than the prior generation’s aluminum tank. Fuel capacity is an ample 1.7 US gallons.
  • The seat base, inner fenders, and side covers were developed to reduce the amount of moisture and dirt that gets to the air cleaner. This helps prevent debris from contaminating the air  lter element.
  • Made with a special density foam, the seat is well shaped and slim to aid the rider’s control of the motorcycle. The seat has a large blue gripper panel that runs nose-to-tail on the cover.
  • The Championship Yellow bodywork is enhanced with a new 2019 graphics package that features distinctive striping and Suzuki logos.
