• design reduces inertial torque while emphasizing linear torque
• design has been optimized to achieve strong torque over a broad rpm range
• fast, linear throttle response
• engine design allows a whole new level of “rider – machine communication”

• reduces engine vibration for excellent rider comfort

• lower end “cap” of the rod is made from the same piece of material as the upper portion; the 2 pieces are “split” apart using a special fracturing process & then machined and re-mated
• design aids in establishing true big end roundness & greater precision in con rod dimensions for excellent durability despite the higher horsepower loads.

• lightweight design for fast engine response
• reduces mechanical vibration
• excellent durability

• ceramic coating sprayed directly on the aluminum block, eliminating the liners & reducing weight
• excellent heat dissipation for consistent power delivery
• coating enhances the thin film of oil between the cylinders & pistons, reducing friction & increasing power

• cylinder is “offset” relative to the crank (toward exhaust side)
• reduces frictional losses between the pistons & the cylinder walls during the power stroke for improved power output

• superior engine & chassis rigidity (engine is a stressed member)
• reduces weight

• cam profiles are designed for excellent torque in the low & mid rpm range

• creates a more compact & shorter engine front to back
• shorter engine allows for optimum engine placement in the “sweet spot” of frame for desired weight distribution & great handling

• system uses throttle position sensor (TPS) & acceleration position sensor (APS)
• 12 hole injectors
• injectors spray fuel directly at the intake valve
• “closed loop system” uses an oxygen sensor to “sniff” spent exhaust & automatically adjust the fuel / air ratio for reduced emissions
• fuel injection benefits include choke-free starting, steady idling during warm up, excellent fuel economy & reduced emissions

• YCC-T electronically controls throttle valves for outstanding throttle response & controllability
• YCC-T system provides precise control of intake air volume for a smoother torque curve
• ECU that controls YCC-T is capable of responding to changes at a speed of 1000th of a second

• enables the rider to adjust the performance characteristics of the engine based on riding preferences or riding conditions
• “STD” (standard) Mode emphasizes very linear throttle & torque feel of the engine
• “A” Mode allows the rider to enjoy even sportier engine performance in the low to mid rpms
• “B” Mode reduces throttle response for riding situations that require softer power characteristics, such as slippery or wet conditions
• D-Mode button is conveniently located on the RHS handle bar switch gear

• slipper clutch reduces the negative effects of engine braking on handling & suspension
• reduces rear wheel hop/ chatter when decelerating for improved riding performance & smoother corner entries
• assist function reduces clutch lever effort by up to 20%

• benefit is a wide torque curve & exciting intake sound that accentuates the exhaust note
• viscous paper type air filter is used

• gear ratios are optimized to accentuate the torque & throttle response of the engine

• aluminum side covers (left & right sides) adds style to the rad

• produces a strong spark for fast starts
• provides precise ignition timing / mapping for optimum engine performance at all rpms

• muffler is a triple expansion type with a 3-way honeycomb catalyzer to reduce harmful emissions
• low mounted design centralizes mass for excellent handling & light weight feeling

• provides an optimized rigidity balance for sporty handling & excellent stability
• engine is a stressed member of the chassis, allowing a lighter, more compact main frame
• light, agile handling qualities

• upright, natural riding position offers a balance between sporty riding & excellent rider comfort

• 1440 mm (56.7″) wheelbase, 25 degrees of rake & 103 mm of trail
• front to rear weight distribution is 51 / 49%
• lean angle is approximately 50 degrees, highlighting the sporty nature of the XSR900
• chassis dimensions & shape are designed to enhance the qualities of the 3 cylinder engine & to centralize mass & lower the centre of gravity

• allows easy access to rear suspension components
• reduces costs in the event of damage

• external design means the swingarm mounts on the outside of the frame spars… not the inside
• external design keeps unit narrower in the seat – fuel tank junction which influences seat height & makes it easier to touch the ground
• lightweight design reduces unsprung weight for superior suspension performance
• excellent rear wheel traction & control

• adjustments include; 15 mm of spring preload adjustment & 12-way rebound damping
• inverted design benefits include: reduced “unsprung” weight & reduced fork flex since the larger diameter tubes are gripped in the triple clamps
• adjustable design allows the rider to tailor suspension settings to match rider weight, load, road conditions & riding style to maximize suspension performance & handling

• rear shock adjustments include: 7-steps of spring preload & 3 turns of rebound damping

• radial mount design helps to reduce caliper distortion for improved braking performance
• master cylinder uses a 16 mm piston
• excellent stopping power & control with good lever feedback

• controlling ECU & hydraulic unit are combined into a single compact unit
• when ABS system senses impending wheel lock-up (via active type wheel sensors) it regulates hydraulic pressure to the point just before the wheel(s) lock-up
• ABS benefits include; excellent control under hard braking or when braking on wet, slippery or loose surfaces
• design reduces weight & centralizes mass

• lightweight design reduces unsprung weight for excellent suspension & handling characteristics
• front rim size is MT3.50-17
• rear rim size is MT5.50-17

• lightweight & strong
• offers a comfortable, upright riding position for excellent all day riding comfort
• traditional design allows easy replacement to a different “bend” if desired

• slim design with great knee grip
• reserve portion of the tank is 2.7 litres (low fuel light illuminates)
• internal electric fuel pump
• exterior replaceable tank covers /side panels… reduce expenses if damaged

• seat height is 830 mm (32.7″)

• functions (all digital) include: speedo, bar-style tachometer, odometer, dual trip meters, fuel gauge, fuel reserve trip meter (counts kilometers since low fuel warning flashed) coolant temp, gear indicator, instant & average fuel consumption, clock, intake air temp, D-mode display, TCS indicator & ECO indicator
• full range of warning lights including ABS & TCS status
• adjustable background illumination

• highlights the XSR900’s “neo-retro authentic sports styling”

• front fender with aluminum stay, fuel tank panels (3), side covers, rear fender , mirrors & mud guard

NOTE: The XSR900 offers a significant level of power and performance. It is not intended for novice or inexperienced riders.
