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. Failure to comply with these recommendations will probably lead to a crash or an accident, with a consequent risk of personal injury or death. A wet surface reduces brakes efficiency. DANGER In case of wet ground the braking distance will be doubled, since both brakes and tyres drives on the road surface are extremely reduced by the water present on the road surface. Any water on brakes, after washing the vehicle or driving on a wet road surface or crossing puddles or gips, can wet brakes so as to greatly reduce their efficiency. Failure to comply with these recommendations may lead to serious accidents, with a consequent risk of severe personal injuries or death. Brakes are critical safety components. Do not ride the vehicle in case brakes are not working at their best. Check for brakes proper operation before every trip. Brake fluid is an irritant. Avoid contact with eyes or skin. In the event of accidental contact, wash affected body parts thoroughly. In the event of accidental contact with eyes, contact an eye specialist or seek medical advice. DO NOT RELEASE BRAKE FLUID INTO THE ENVIRONMENT.KEEP AWAY FROM CHILDREN. When handling brake fluid, take care not to spill it onto plastic or paint-finished parts or they will damage. DANGER Do not use any brake fluids other than the specified type. Never mix different types of fluids to top up level, as this will damage the braking system. Do not use brake fluid from containers which have been kept open or in storage for long periods. Any sudden changes in play or hardness in the brake levers are warning signs of problems with the hydraulic circuits. Ensure that the brake discs and brake linings have not become contaminated with oil or grease. This is particularly important after servicing or inspections. Make sure the brake lines are not twisted or worn. Prevent accidental ingress of water or dust into the circuit. Wear latex gloves when servicing the hydraulic circuit. DISC BRAKES DANGER The brakes are the parts that most ensure your safety and for this reason they must always be perfectly working; check them before every trip. A dirty disc soils the pads. Dirty pads must be replaced, while dirty discs must be cleaned with a high-quality degreaser. Perform the maintenance operations with half the indicated frequency if the vehicle is used in rainy or dusty areas, on uneven surfaces or on racetracks. When the disc pads wear out, the level of the fluid decreases to automatically compensate for their wear. The front brake fluid reservoir is located on the right handlebar, near the front brake lever. The rear brake fluid reservoir is located under the right fairing. Do not use the vehicle if the braking system leaks fluid.

RUNNING-IN

RUNNING-IN RECOMMENDATIONS
The running-in of the engine is essential to ensure its duration and correct functioning. If possible, drive on hilly roads and/or roads with many bends, so that the engine, the suspensions and the brakes undergo a more effective running-in. During running-in, change speed. In this way the components are first "loaded" and then "relieved" and the engine parts can thus cool down. Even if it is important to stress the engine components during running-in, take care not to exceed. WARNING Only after the first 2000 km (1243 mi) of running-in you can expect the best performance levels from the vehicle. Keep to the following indications: Do not open the throttle completely if the speed is low, both during and after the running-in. During the first 100 km (62 mi) pull the brakes with caution, avoiding sharp and prolonged brakings. This ensures a correct bedding-in of the pads on the brake disc. During the first 1000 km (621 mi) never exceed 5000 rpm (see table). WARNING After the first 1000 km (621 mi), Dealer carry out the checks indicated in the column "After running-in", see (REGULAR SERVICE INTERVALS CHART), in order to avoid hurting yourself or other people and/or damaging the vehicle. Between the first 1000 km (621 mi) and 2000 km (1243 mi) drive more briskly, change speed and use the maximum acceleration only for a few seconds, in order to ensure better coupling of the components; never exceed 6000 rpm (see table). After the first 2000 km (1243 mi) you can expect better performance from the engine, however, without exceeding the maximum allowed [7600 rpm].

NEVADA CLASSIC 750 IE

A SPIRITED CLASSIC
Italian creativity and traditional Moto Guzzi character mark the classical yet modern lines that set the Nevada Classic 750 i.e. apart from the crowd. The Nevada Classic 750 i.e. combines eye-catching style that is never out of date with the latest technology in a truly versatile motorcycle that is always easy and rewarding to ride. Completely renewed in looks and technology by thorough and careful restyling and development, the baby from Mandello del Lario stands alone in its class as the only entry level custom with a practical shaft drive plus electronic fuel injection. Just like every other machine in the Moto Guzzi range, the Nevada Classic i.e. also boasts an ecological exhaust system with oxygen probe catalyser. Designed to tackle rush-hour traffic and twisting bends with the same ease, the Nevada dominates the road thanks to an efficient suspension system, ergonomic riding position and generous, smooth power with bags of torque always on tap. Elegant and versatile, the new Nevada is the perfect machine for all riders who live in todays hectic cities but cannot live without the spirit of Moto Guzzi. Nevada Classic 750 i.e., freedom to love riding.

A MATTER OF FEELING

With its elegant interpretation of the custom ethos, the Nevada Classic 750 i.e. is instantly seductive. Thanks to the instant confidence it inspires, it also delivers convincing performance straight after straight, bend after bend. There is nothing excessive about the Nevada. The riding position with perfectly ergonomic handlebars, seat and footrests avoids the extremes of other customs and ensures comfort and control in town traffic and on long journeys. Reduced seat height makes low speed manoeuvring a piece of cake too, so that you are always in total control of the Nevada under all conditions. Stability, road holding and comfort are ensured by a perfectly balanced chassis and the limited wheelbase of the compact, lightweight Nevada gives tremendous agility. The robust 40 mm fork accurately follows rider input for precision cornering and the two hydraulic shock absorbers at the rear perfectly match the die-cast, light alloy swingarm as well as offering preload adjustment to adapt to different road and load conditions.

ITS A SIN TO SAY NO

With its high level of equipment and unbeatable comfort and ridability, the Nevada Classic 750 i.e. is designed to satisfy even the most demanding rider as well as offer an ideal first approach to the world of the great touring Guzzis. The new seat profile guarantees comfort even two up; the handlebars and grips have been redesigned for improved grip and control; even the clutch lever gives a smoother action. Super-safe stopping is always to hand from a powerful braking system with a mighty 320 mm floating disk with four piston calliper at the front and a 260 mm disk at the rear. Braking efficiency has also been enhanced by a series of improvements to the master cylinders, callipers and brake lines. The electronic injection delivers superior power that can be used to the full by the reliable shaft drive. The Nevadas instrumentation is that of a real tourer, with ultra-classic analog speedometer and electronic rev counter and an LCD display for odometer, trip counter, temperature and time.
TOO BEAUTIFUL TO LEAVE ALONE
With its long, low lines, the custom look is always a classic. And the Nevada Classic 750 i.e. has plenty of traditional custom fittings too, like a big round headlight, raking front fork, impressive side-mounted chrome exhausts, metallic teardrop tank, king and queen seat with contrasting stitching, an abundance of chrome and spoked wheels. Yet clever restyling work has modernised the lines of the side panels, shock cover panels, seat, rear mudguard, tail light and rider footrests to achieve refreshingly new lines. The evolution of the Nevada Classic 750 i.e. towards an ever wider public with a careful eye for the latest trends in style is confirmed by the bikes sophisticated new colours: shiny, high-tech Light Grey as well as the traditional Guzzi Black, decorated with inserts in darker grey and red. The Nevada Classic 750 i.e.. a fascination that grows in time.

Filter box. The filter box has been designed using the latest CFD (Computational Fluid Dynamics) calculation methods. The large size filter box ensures maximum efficiency and features an extremely advanced Helmotz resonator to respect the latest noise emission standards without penalising performance. Ease of maintenance was also taken into consideration in designing the box, and the filter can be removed and replaced in just a few minutes.
A NEW GENERATION OF ENGINES. ENGINE.
750 cc is an engine capacity that has written some of the most glorious chapters in the history of Moto Guzzi. Today this same engine size represents entry into the world of the Eagle of Mandello. The 750 class attracts a wide range of riders, including lady riders who demand not just performance, but reliability, safety, and easy riding. That is why Moto Guzzi is putting so much effort into the development of its 750 cc engines, adding innovations and modifications to enhance performance and personality. The adoption of electronic fuel injection for the Nevada Classic 750 i.e. cc engine is the first big step in this direction. The new fuel injected engine delivers smooth, progressive power, with greater efficiency under all conditions, from hot and cold starting to acceleration and maximum engine speed. Moto Guzzi has neglected nothing in the search for a technically advanced balance between performance, reliability and low consumption.
Electronic fuel injection. The fuel injection system is state of the art for the motorcycling industry. It features a Lambda type oxygen sensor plus sensors for engine temperature (in the right hand cylinder head), aspirated air, atmospheric pressure and throttle position. The system guarantees an optimum air/fuel mix for maximum catalyser efficiency (and in respect of Euro 2 standards) and maximum performance in terms of response, smooth acceleration and maximum power. The fuel injection system features a double 36 mm throttle body with twin cable operation.
Valve gear. The camshaft has a new, more efficient profile. Reference pins between the camshaft and the drive gear, and between the camshaft and phonic wheel ensure minimum tolerance in valve timing.
The injectors are ultra-compact and direct the fuel spray directly at the intake valves, guaranteeing instant response and minimum emissions. The rail is manufactured from a special, latest generation technopolymer. The catalysers Lambda oxygen sensor analyses exhaust gases and constantly adjusts carburation to optimise combustion efficiency and minimise emissions. Other important innovations include a phonic wheel on the camshaft and a temperature pick-up on the valve cover. Significantly, Moto Guzzi is one of the very few motorcycle manufacturers to install catalysers on all its models. This is because Moto Guzzi attributes great importance to the environment and on coherent design policies. The triple catalysed exhaust with car type Lambda oxygen sensor comes well within Euro 2 standards. Pistons and cylinders. Upper oil control rings form part of an optimised piston ring arrangement that minimises blow-by. This new piston design not only ensures excellent reliability but reduces oil consumption too. Special graphite based coatings have also significantly reduced friction and wear.

CLUTCH.

Lubrication. The renewed engine lubrication system features an oil pressure sensor and an improved pressure control valve for more efficient oil circulation. The rocker arms also have sealing boots to prevent pressure loss and ensure a better oil circuit seal. Quality starts on the assembly line, with precision alignment references used to reduce oscillation of the flywheel/clutch assembly. All clutch components have been balanced to reduce clutch vibration. This is particularly noticeable at low engine speeds. A new friction lining material has been adopted too, to reduce the effort needed to operate the clutch lever.
Gear selection is instant and precise, thanks to the index lever and star on the desmodromic shaft. Extremely accurate coupling between the gear engagement forks and the desmodromic shaft means smoother, slicker and more precise gear changes. A number of modifications have been made to the pre-selector too, including a new lubrication system, new counter-springs and fork guide springs, and new surface treatments. The lug angles have also been modified for faster and smoother disengagement. Between them, these improvements mean effortless gear changes and easier riding. One of the most important gearbox innovations is the new gear and neutral selector with index lever and star on the desmodromic shaft. The advanced design of this fundamental part ensures slick gear and neutral selection. Great care has also been taken in the choice of gearbox materials: all gears are made from 18 Ni Cr Mo 5 steel. Machining tolerances are also finer, thanks to modern, high precision and top quality machining processes. Gearbox lubrication has been improved too, with a new technopolymer feeder to ensure correct lubrication of the gears at all times. Even the lubricants have been specially selected for maximum lubrication efficiency (AGIP ROTRA 80W 90 MP/S for the gearbox and TRUCK GEAR 85W 140 for the shaft drive). This means greater reliability, extended part life and a far smoother gearshift action.
