Riding PrecautionsBreak-in Period
During the first 300 miles (500 km) of running,follow these guidelines to ensure your vehicle'sfuture reliability and performance.● Avoid full-throttle starts and rapid
acceleration.● Avoid hard braking and rapid down-shifts.● Ride conservatively.
BrakesObserve the following guidelines:● Avoid excessively hard braking and
downshifting.u Sudden braking can reduce the vehicle's
stability.u Where possible, reduce speed before
turning; otherwise you risk sliding out.
● Exercise caution on low traction surfaces.u The tires slip more easily on such
surfaces and braking distances arelonger.
● Avoid continuous braking.u Repeated braking, such as when
descending long, steep slopes canseriously overheat the brakes, reducingtheir effectiveness. Use engine brakingwith intermittent use of the brakes toreduce speed.
● For full braking effectiveness, operate boththe front and rear brakes together.

# Anti-lock Brake System (ABS) on FrontWheel
This model equipped with an Anti-lock BrakeSystem (ABS) designed to help prevent the frontbrake from locking up during hard braking.● There is no ABS function to the rear wheel.● ABS does not reduce braking distance. In
certain circumstances, ABS may result in alonger stopping distance.
● ABS does not function at speeds below 6mph (10 km/h).
● The brake lever may recoil slightly whenapplying the brakes. This is normal.
● Always use the recommended front/reartires and sprockets to ensure correct ABSoperation.
# Engine BrakingEngine braking helps slow your vehicle downwhen you release the throttle. For furtherslowing action, downshift to a lower gear. Useengine braking with intermittent use of thebrakes to reduce speed when descending long,steep slopes.
# Wet or Rainy ConditionsRoad surfaces are slippery when wet, and wetbrakes further reduce braking efficiency.Exercise extra caution when braking in wetconditions.If the brakes get wet, apply the brakes whileriding at low speed to help them dry.

Exhaust Emission Control SystemThe exhaust emission control system includesthe following components that should not needadjustment, although periodic inspection byyour dealer is recommended.
# PGM-FI SystemThe PGM-FI (programmed fuel injection) systemuses sequential multiport fuel injection, and iscomprised of air intake, engine control, fuelcontrol, and exhaust control subsystems. Theengine control module (ECM) uses sensors todetermine how much air enters the engine, andthen controls how much fuel to inject.
# Ignition Timing Control SystemThe ignition timing control system adjusts theignition timing to reduce the amount of HC,CO, and NOx produced.
# Catalytic ConvertersThe exhaust system contains one or morecatalytic converters. Catalytic converters use acatalyst to convert most of the harmful exhaustgas compounds into harmless compounds.
Evaporative Emission Control System50 STATE (meets California)An evaporative emissions control system uses acanister filled with charcoal to adsorb fuel vaporfrom the fuel tank while the engine is off. Thevapor is drawn into the engine and burnedwhile riding.
