You are now the owner of a state-of-the-art sport motorcycle that guarantees to bring you lots of fun and enjoyment, provided that you clean and maintain it appropriately. Please insert the serial numbers of your motorcycle in the boxes below Frame number Engine number Key number Stamp of dealer All information contained is without obligation. [. . . ] Accordingly, you can mount the handlebar in 4 different positions. 3 4 For this purpose, remove screws [3] of the handlebar clamps and screws [4] of the handlebar support. Position the handlebar support, and tighten screws [4] to 40 Nm (30 ft. lbs). Mount the handlebar and handlebar clamps, and tighten screws [3] to 20 Nm (15 ft. lbs). The gap between the handlebar support and the handlebar clamps should be the same size in the front and in the rear. The screws [4] must be secured with loctite 243. mm 15 2 3, 5 mm 1 MAINTENANCE WORK ON CHASSIS AND ENGINE » Check chain tension A Jack the motorcycle up on its frame so that the rear wheel no longer touches the ground. In the course of this procedure, the upper chain portion [A] must be taut (see drawing). ­ Excessive tensioning of the chain will put additional load on the components of the secondary drivetrain (chain, bearings of transmission and rear wheel). Aside from resulting premature wear, if worst comes to worst the chain may rupture or the countershaft of the transmission may break. ­ Too much slack in the chain, on the other hand, can result in the chain jumping off the chain wheels. If this happens, the chain could also block the rear wheel or damage the engine. ­ In either case the operator is likely to lose control of the motorcycle. 8-1 0m m/ 0. 30. 4 in Correct chain tension B 1 3 2 Loosen collar nut [1], loosen lock nuts [2], and turn right and left adjusting screws [3] equally far. To ensure the correct alignment of the rear wheel, the marks at the left and right chain adjusters must be positioned identically in relation to the reference marks [B]. Clean and grease the adjusting screws regularly (Motorex Long Term Grease 2000). Before tightening the collar nut, verify that the chain adjusters [4] are sitting close to the adjusting screws and that the rear wheel has been aligned with the front wheel. ­ If you don't happen to have a torque wrench at hand, make sure you have the tightening torque corrected by a KTM dealer as soon as possible. A loose axle may lead to an unstable driving behavior of your motorcycle. A loose wheel spindle may lead to an unstable behavior of your motorcycle. NOTE: The large adjusting range of the chain adjusters (32mm) allows you to use different secondary ratios in combination with the same chain length. The chain adjusters [4] can be rotated by 180°. 4 2 4 B 3 ENGLISH 33 MAINTENANCE WORK ON CHASSIS AND ENGINE » Chain maintenance For a long chain life, good maintenance is very important. Chains without X-rings should be cleaned in fireproof solvent regularly and afterwards treated with hot grease or chain spray (e. g. The best way is to use lots of water, but never use brushes or cleaning liquids. After letting the chain dry, you can use a special X-ring chain spray (e. g. [. . . ] ­ Cover the motorcycle with an air permeated tarpaulin or blanket. Do not use airtight materials as a possible humidity might not be able to escape and could cause corrosion. It would be very bad to let the engine run for a short time during the storage period. The engine would not get warmed up enough and the thus developed steam would condense during the combustion process and cause the valves and exhaust to rust. USE AFTER A PERIOD OF STORAGE ­ ­ ­ ­ ­ Mount the charged battery (regard polarity). [. . . ]
