The Suzuki Brand has launched its new 2018 Suzuki RM-Z450 Motocross providing an ultimate riding on rough surfaces. It features the sleek, race-ready appearance covering the powerful engine and nimble chassis provides an ultimate handling experience. This motocross has been developed with the Suzuki’s Run, Turn and Stop philosophy making it stronger bike. It comes with the stronger brakes providing the better stopping power, wider spread of engine muscle with the higher peak power. The chassis and frame are kept stronger, lighter and more nimble for provide an ultimate performance in all conditions. Following is the review of newly launched 2018 Suzuki RM-Z450 Motocross along with the specification and pics.
2018 Suzuki RM-Z450 Motocross – Specification and Pics
The all-new 2018 Suzuki RM-Z450 Motocross comes with the 449cc of liquid-cooled 4-stroke engine featuring the 4-valve DOHC engine. This is the latest engine providing the best performance plus it is the reliable and fuel-injected powerplant. It has the higher peak horsepower with the more torque at the lower engine speeds for an improved throttle response through the entire rev-range. The cylinder head intake port shape is changed to the tumble flow the fuel or air mixture by 25% to help in an increase of power output. The air cleaner opening is kept 30% larger and it is combined with the more direct air cleaner outlet tube path to its throttle body to increase air flow. Its latest fuel-injection system creates an extra-smooth power delivery, high fuel efficiency, and superb reliability. This new bike has the unique throttle body design with the relocated fuel injector fed by the higher-pressure fuel pump directly sprays fuel at the butterfly valve to improve the atomization of the fuel/air charge. The design of throttle body eliminates the complex control linkage so that the riders feel the direct connection to the engine. The profile of intake camshaft is changed which includes the more valve lift that the prior model increasing power at all engine speeds. The all-new compact aluminum cylinder is finished with the Suzuki Composite Electrochemical Material (SCEM) coating for lightweight, durability and efficient transfer of heat. The coating of a piston is upgraded to include the strengthening ribs news the wrist pin bosses to match the component reliability to higher horsepower. The starting of the engine is very simple and efficient due to its long kick starter lever, well refined internal gears, larger air cleaner and breather system. The new automatic decompression system works efficiently and precisely for an ultimate performance. The high-flow exhaust system meet the terms of AMA sound regulation. The new engine protectors help guard the coolant pump and the stator cover from the stones and debris.
The all-new 2018 Suzuki RM-Z450 Motocross features the faster traction management system. The all-new Electronic Control Module (ECM), which continually measures the opening of throttle, engine speed and the gear position then it carefully adjusts the ignition timing and the fuel injector to fine-tune the output of an engine to deliver the best traction for riding conditions. The Suzuki Holeshot Assist Control (S-HAC) is the selectable launch system, which is derived from the factory race bike to enable the rider to have an outstanding start. There are three different modes available in this Suzuki motocross and rider can choose the best option according to their skill level and starting conditions.
- A-mode is on hard or slippery surfaces. This mode enables the S-HAC to alter the ignition timing at the moment of launch and the ride over the gate to reduce the wheel slip. It also increases the ignition timing for stronger acceleration. When the rider reaches on the third gear or after 1.2 seconds, this system shuts off and returns to normal ignition timing.
- B-Mode is most suitable for that condition when better traction with the aggressive launch is required. The S-HAC will advance the ignition timing to allow an increased throttle response and stronger acceleration off the line. The alternation in ignition timing is similar to the A-Mode but it will increase the overall timing. This mode will shut off or return to normal operation after 4.5 seconds passed since throttle opening, shifting to 4th gear or when the throttle is closed. It is for skilled riders for aggressive riding.
- Base Mode is a standard power launch and no action is required on the S-HAC switch. This mode is designed for motocross use, lightweight, battery-less and electronic fuel injection system providing an efficient delivery of power.
The all-new 2018 Suzuki RM-Z450 Motocross comes with the 5-speed transmission providing the best gear shifting operation. Its operation is been improved with the precisely machined shift cam for best gear selection. The specialized machining processes increase the precision of the matching gears. All-new multi-plate wet clutch uses the rack and pinion clutch release mechanism for best operation. The lighter-weight chain guide is shaped to precise route the drive chain smoothly.
The all-new 2018 Suzuki RM-Z450 Motocross comes with the lightweight frame and its swingarm is carefully designed for best handling. The aluminum-alloy twin-spar frame combines the cast and extruded section for ultimate front-and-rear weight distribution while balancing the strength and weight. The overall design is kept same as 2017 Suzuki RM-Z450. Its frame is 700 grams lighter for best performance and the shock absorption for stable handling. The swingarm is assembled with the thinner material for lower the weight about 100 grams. Its wheelbase is kept shorter and the frame head pipe is relocated to provide best handling characteristics. The new hexagonal aluminum rails are being used on the sub-frame for lighter weight and the slimmer appearance and easier air-filter service. The sub-frame is kept thinner to make the overall body slim and compact. Its suspension is being inspired from the GSX-R1000R Superbike and it contains the new SHOWA Balance Free Rear Cushion (BFRC) shock absorber. This motocross features the fully adjustable BERC control damping for comfort ride and better absorption over bumps. It features the larger 270 mm of wave-style front brake rotor for best stopping performance. It’s light upper fork bracket is complemented with its new front suspension and handlebars. The new strong Renthal aluminum tapered handlebar has the straighter bend, which helps the rider during aggressive maneuvering. The latest generation SHOWA coil spring front fork has the larger inner tubes and rod pipes for extreme durability and strength. The tuning of front suspension and maintenance is balanced providing the greater benefit during frequent riding. The new design of rear brake master cylinder is carefully mounted on the frame to reduce dirt contamination. Its wheels contain the black anodized rims with the cross-section design, which maintains the strength while reducing an un-sprung weight. This motocross features the Bridgestone Battlecross X30 tires providing the better grip. Its plastic fuel tank weighs half-a-pound provides the fuel capacity of 1.7 gallons. Its seat is slim provides the best riding position and greater comfort. The Suzuki Championship Yellow bodywork is enhanced with its distinctive blue and black striping and new logo graphics.
