Motorcycles are fascinating vehicles, which can give you an unsurpassed feeling of power and freedom. However, they also impose certain limits, which you must accept; even the best motorcycle does not ignore the laws of physics. Regular care and maintenance are essential for preserving your motorcycles value and operating condition. Moreover, what is true for the motorcycle is also true for the rider: good performance depends on being in good shape. Riding under the influence of medication, drugs and alcohol is, of course, out of the question. Motorcycle riders more than car drivers must always be at their mental and physical best. Under the influence of even small amounts of alcohol, there is a tendency to take dangerous risks. Protective clothing is as essential for the motorcycle rider as seat belts are for car drivers and passengers. Always wear a complete motorcycle suit (whether made of leather or tear-resistant synthetic materials with protectors), sturdy boots, motorcycle gloves and a properly fitting helmet. Optimum protective wear, however, should not encourage carelessness. Though full-coverage helmets and suits, in particular, create an illusion of total safety and protection, motorcyclists will always be vulnerable. Riders who lack critical self-control run the risk of going too fast and are apt to take chances. This is even more dangerous in wet weather. The good motorcyclist rides safely, predictably and defensively avoiding all dangers, including those caused by others. Enjoy your ride!

1. Spark plug gap

Spark plug inspection
The spark plug is an important engine component and should be inspected periodically, preferably by a Yamaha dealer. The condition of the spark plug can indicate the condition of the engine. The ideal color on the white insulator around the center electrode is a medium-to-light tan color for a motorcycle that is being ridden normally. Do not attempt to diagnose any problems yourself. Instead, take the motorcycle to a Yamaha dealer. The spark plug should be periodically removed and inspected because heat and deposits

will cause the spark plug to slowly break down and erode. If electrode erosion becomes excessive, or if carbon and other deposits are excessive, the spark plug should be replaced with the specified plug. Specified spark plug: BR9ES (NGK) Before installing the spark plug, measure the electrode gap with a wire thickness gauge and adjust it to specification. Spark plug gap: 0.7 ~ 0.8 mm

Wheels
9 To ensure maximum performance, long service, and safe operation, note the following: 8 Always inspect the wheels before a ride. Check for cracks, bends, or warpage of the wheels. If any abnormal condition exists in a wheel, consult a Yamaha dealer. Do not attempt even small repairs to the wheel. If a wheel is deformed or cracked, it must be replaced. 8 Tires and wheels should be balanced whenever either one is changed or replaced. Failure to have a wheel balanced can result in poor performance, adverse handling characteristics, and shortened tire life. 8 Ride at moderate speeds after changing a tire since the tire surface must first be broken in for it to develop its optimal characteristics.

Troubleshooting
Although Yamaha motorcycles receive a rigid inspection before shipment from the factory, trouble may occur during operation. Any problem in the fuel, compression, or ignition systems can cause poor starting and loss of power. The troubleshooting chart describes a quick, easy procedure for making checks. If your motorcycle requires any repair, bring it to a Yamaha dealer. The skilled technicians at a Yamaha dealership have the tools, experience, and know-how to properly service your motorcycle. Use only genuine Yamaha parts on your motorcycle. Imitation parts may look like Yamaha parts, but they are often inferior. Consequently, they have a shorter service life and can lead to expensive repair bills. 9

9 The exposure of its technology makes a motorcycle charming but also vulnerable. Although high-quality components are used, they are not all rust-resistant. While a rusty exhaust pipe may remain unnoticed on a car, it does look unattractive on a motorcycle. Frequent and proper care, however, will keep your motorcycle looking good, extend its life and maintain its performance. Moreover, the warranty states that the vehicle must be properly taken care of. For all these reasons, it is recommended that you observe the following cleaning and storing precautions. Before cleaning 1. Cover up the muffler outlet with a plastic bag. 2. Make sure that all caps and covers as well as all electrical couplers and connectors, including the spark plug cap, are tightly installed. 3. Remove extremely stubborn dirt, like oil burnt onto the crankcase, with a degreasing agent and a tooth or bottle brush, but never apply such products onto seals, gaskets, sprockets, the drive chain and wheel axles. Always rinse the dirt and degreaser off with water.

EAU01518

Cleaning After normal use Remove dirt with warm water, a neutral detergent and a soft clean sponge, then rinse with plenty of clean water. Use a brush for hard-toreach parts. Tougher dirt and insects will come off more easily if the area is covered with a wet cloth for a few minutes before cleaning.

ECA00010

8 Avoid using strong acidic wheel cleaners, especially on spoked wheels. If you do use such products for hard-toremove dirt, do not leave it on any longer than instructed, then thoroughly rinse it off with water, immediately dry the area and apply a corrosion protection spray.

EWA00001

Make sure that there is no oil or wax on the brakes and tires. If necessary, clean the brake discs and linings with a regular brake disc cleaner or acetone, and wash the tires with warm water and mild soap. Then, carefully test the motorcycle for its braking performance and cornering behavior.
NOTE: Consult a Yamaha dealer for advice on what products to use.

ECA000013

8 Apply spray oil and wax sparingly and wipe off any excess. 8 Never apply oil or wax on rubber and plastic parts, but treat them with a suitable care product. 8 Avoid using abrasive polishing compounds as they wear away the paint.
5AE-9-E3 (ENG) 4/11/0 11:06 AM Page 87

Storage

Short-term Always store your motorcycle in a cool, dry place and, if necessary, protect it against dust with a porous cover. Long-term Before storing your motorcycle for several months: 1. Follow all the instructions in the Care section of this chapter. 2. Drain the carburetor float chamber by loosening the drain bolt; this will prevent fuel deposits from building up. Pour the drained fuel into the fuel tank. 3. Only for motorcycles equipped with a fuel cock which has an OFF position: Turn the fuel cock to OFF. 4. Fill up the fuel tank and add fuel stabilizer (if available) to prevent the fuel tank from rusting and the fuel from deteriorating. 5. Perform the following steps to protect the cylinder, piston rings, etc. from corrosion. a. Remove the spark plug cap and spark plug. b. Pour a teaspoonful of engine oil into the spark plug bore. c. Install the spark plug cap onto the spark plug and place the spark plug on the cylinder head so that the electrodes are grounded. (This will limit sparking during the next step.) d. Turn the engine over several times with the starter. (This will coat the cylinder wall with oil.) e. Remove the spark plug cap from the spark plug, install the spark plug and then the spark plug cap.

8 Storing the motorcycle in a poorly ventilated room or covering it with a tarp while it is still wet will allow water and humidity to seep in and cause rust. 8 To prevent corrosion, avoid damp cellars, stables (because of the presence of ammonia) and areas where strong chemicals are stored.

EWA00003

When turning the engine over, be sure to ground the spark plug electrodes to prevent damage or injury from sparking.

6. 1 7. Lubricate all control cables and the pivoting points of all levers and pedals as well as of the sidestand/centerstand. Check and, if necessary, correct the tire air pressure, then raise the motorcycle so that both of its wheels are off the ground. Alternatively, turn the wheels a little every month in order to prevent the tires from becoming degraded in one spot. Cover up the muffler outlet with a plastic bag to prevent moisture from entering. 9. Remove the battery and fully charge it. Store it in a cool, dry place and recharge it once a month. Do not store the battery in an excessively cold or warm place (less than 0C or more than 30C). For more information, see Battery storage in the chapter PERIODIC MAINTENANCE AND MINOR REPAIRS. NOTE: Make any necessary repairs before storing the motorcycle.

The way we see it theres only one machine that delivers everything you want. It can only be the TDR125 from Yamaha.
Aggressive Supermotard styling gives the TDR a radical in-your-face image that other 125s can only dream about! Instant throttle response and exhilarating performance come as standard with the high-tech liquid-cooled engine. And the full-sized Deltabox chassis and long-travel suspension deliver athletic handling and give this class-leading 125 a real big-bike feel.
Liquid-cooled engine The liquid-cooled 125 cc 2-stroke engine drives through a 6-speed gearbox and features a power-boosting Yamaha Power Valve System (YPVS) for extra-strong performance. And for quick getaways this reliable and economical engine features an electric starter.
Front forks/Brake/Wheel/Tyre TDR125s high-specification front end features heavy-duty long-travel forks that give a comfortable ride and smooth roadholding. Lightweight 3-spoke front wheel runs with a wide-profile tyre, and the large-diameter disc brake delivers strong and progressive stopping power.
Rear suspension/Rear wheel/Rear tyre For smooth roadholding this high-tech 125 is equipped with a Monocross rear suspension system and strong box-section swingarm. Wide rear tyre emphasises the big-bike image, and the 3-spoke alloy wheel and compact rear disc minimise unsprung weight.
Instruments Shielded from sunshine and rain by the aerodynamic twin-headlight cowl, the compact instrument console includes a lightweight speedometer and tachometer as well as a range of easy-to-read indicator lamps.
U-lock space Underneath the TDR125s long and comfortable dual seat youll find a useful storage compartment that is designed to carry a U-lock or other similar security devices. The Yamaha U-lock (accessory) offers added security when your bike is parked, and when not in use it can be quickly stored under the seat.
