Press the chain upward at the end of the chain sliding component. The distance between the chain and the swing arm should be approx. In the course of this procedure, the upper chain portion [A] must be taut (see drawing). If necessary, correct the chain tension. ­ 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.

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. ­ Tighten the collar nut with the required torque. 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.
