GENERAL INFORMATION PEGASO 650 1.1.2. SAFETY WARNINGS The following precautionary warnings are used throughout this manual in order to convey the following messages: Safety warning. This symbol appears, whether in the manual or on the vehicle itself, to indicate a personal injury hazard.
GENERAL INFORMATION PEGASO 650 1.2. GENERAL RULES 1.2.1. BASIC SAFETY RULES CARBON MONOXIDE Should it be necessary to perform some operations with the vehicle running, make sure to work outdoors or in a well- aerated room. Avoid starting the engine indoors. In case you are working indoors, use a gas exhaust system.
Page 12
GENERAL INFORMATION PEGASO 650 DANGER Take care not to spill coolant onto hot engine parts and exhaust system. It may ignite and produce invisible flames. Wear latex gloves when servicing. Although toxic, it has a sweet taste that might attract animals. Never leave coolant in open container or in a position easily reachable by animals.
Page 13
NOTE All bearings must rotate freely with no hard spots or noise. Replace any bearings that do not meet these requirements. Use ORIGINAL aprilia SPARE PARTS only. Use the specified lubricants and consumables. Where possible, lubricate a part before assembly.
GENERAL INFORMATION PEGASO 650 1.3. DANGEROUS ELEMENTS 1.3.1. WARNINGS FUEL DANGER The fuel used to operate engines is highly flammable and becomes explosive under particular conditions. Refuelling and engine service should take place in a well-ventilated area with the engine stopped. Do not smoke when refuelling or in the proximity of sources of fuel vapours, avoid flames, sparks and any element that could ignite fuel or provoke explosions.
Page 15
GENERAL INFORMATION PEGASO 650 BRAKE FLUID NOTE This vehicle is fitted with front and rear disc brakes. Each braking system is operated by an independent hydraulic circuit. The information provided below applies to both braking systems. DANGER Do not use the vehicle in case brakes are worn out or do not work properly. The brakes are the parts that most ensure your safety and for this reason they must always be perfectly working.
Page 16
GENERAL INFORMATION PEGASO 650 COOLANT DANGER Coolant is toxic when ingested, contact with eyes or skin may cause irritation. In the event of contact with your skin or eyes, rinse repeatedly with abundant water and seek medical advice. In the event of ingestion, induce vomiting, rinse mouth and throat with abundant water and seek medical advice immediately.
Page 17
GENERAL INFORMATION PEGASO 650 TYRES WARNING If tyres are excessively inflated, the vehicle will be hard, difficult and uncomfortable to ride. In addition, the roadworthiness, mainly on wet surfaces and during cornering, will be impaired. Flat tyres (insufficient pressure) can slip on the rim and make you lose the control of the vehicle. In this case too, both vehicle roadworthiness, manoeuvrability and brake efficiency will be impaired.
After the first 1000 km (621 mi), have the checking operations indicated in the column "After running- in" carried out by an aprilia Authorised Dealer, see REGULAR SERVICE INTERVALS CHART, in order to avoid hurting yourself or other people and/or damaging the vehicle.
GENERAL INFORMATION PEGASO 650 1.5. VEHICLE IDENTIFICATION 1.5.1. POSITION OF THE SERIAL NUMBERS These numbers are necessary for vehicle registration. NOTE Altering the vehicle identification numbers is a legal offence. Altering the frame number invalidates the warranty. FRAME NUMBER The frame number (A) is stamped on the right side of the steering column.

ENGINE PEGASO 650 4.2. SECONDARY AIR SYSTEM 4.2.1. SECONDARY AIR The Secondary Air System (SAS) has been developed to reduce carbon oxide and unburnt hydrocarbon emissions in vehicles that are not equipped with a lambda sensor. Natural air (which is rich in oxygen) is channelled into the exhaust stream to trigger a post-combustion process.
Page 104
ENGINE PEGASO 650 At low rpm the valve is activated to bring down carbon monoxide emissions. WARNING When adjusting the CO rate, disable the Secondary Air System or exhaust gas dilution caused by the system would give a wrong reading of the carbon monoxide percentage. See CO ADJUSTMENT for instructions on how to disable the SAS.
