• Cylinder head intake port shape creates a high amount of tumble flow to the incoming fuel/air to increase power output
• Throttle body design locates the fuel injector, fed by a high-pressure fuel pump, so it sprays fuel directly at the butterfly valve to improve atomization of the fuel/air charge
• Intake camshaft profile has more valve lift than the prior generation RM-Z450, increasing power at all engine speeds
• Large air cleaner opening is combined with a more direct air cleaner outlet tube path into the throttle body for high-volume air flow
• Compact rear brake master cylinder is designed to prevent mud from collecting on it and from catching on the rider’s boots
• Resin engine protectors help guard the coolant pump (on the right) and the stator cover (on the left) from debris and stones
• Includes two fuel couplers for quick and easy EFI tuning: one is for a richer-than-stock and another for a leaner-than-stock fuel setting
• 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

Suzuki Holeshot Assist Control (S-HAC) is a selectable launch system derived from the factory race bike to help takeoff from the starting gate for an early lead; with three stages of power adjustment: 1) the moment of initial launch, 2) when crossing the starting gate, and 3) acceleration up to full-speed. There are three S-HAC modes riders can choose for the best option per their skill level and starting conditions:
• Mode A: for hard surfaces or slippery conditions at the starting gate
• Mode B: when conditions at the starting gate have better traction, and a more aggressive launch is desired
• Base Mode: standard power launch, no action required on the S-HAC switch

Includes Suzuki’s MX-Tuner 2.0, which provides quick fuel injection and ignition tuning:
• Using a smartphone application that wirelessly connects to the MX-Tuner’s compact transceiver, fuel delivery and ignition timing can be quickly changed
• The MX-Tuner application can pre-program personalized settings into the ECM that can be activated by plugging in one of the supplied fuel couplers
• Racers and tuners can easily change settings to match performance-related updates
• The application can save a number of settings for different tracks or weather conditions, plus settings can be exchanged with other racers
• Real-time engine data and run-time information are accessible to help you stay on top of bike maintenance

RM Army Edition kit includes:
• Exclusive full-system exhaust from Pro Circuit, with a stainless-steel head pipe, a titanium silencer shell, and a carbon fiber end cap wrapped with a custom RM Army Edition decal
• New RM Army graphics package from Throttle Syndicate
• Color: Champion Yellow No. 2
• Cooling: liquid
• Engine type: single cylinder, 4-stroke, DOHC, 4-valve, compact aluminum cylinder with Suzuki Composite Electrochemical Material (SCEM) coating
• Frame: twin-spar aluminum alloy with cast and extruded sections, hexagonal aluminum rail sub-frame
• Fuel tank: plastic
• Handlebar: Renthal aluminum tapered
• Lubrication: semi-dry sump
• Spark Plug: NGK DIMR8C10
