Bold reference numbers in this section identify parts not shown in the figures alongside the text, but which can be found in the exploded view diagram.

Before carrying out dimensional checks on the frame, you must remove all the superstructures fitted, referring to the removal procedures outlined in the sections of this manual.

The flow chart below illustrates the logical sequence in which the parts are to be removed from the motorcycle and gives a reference to the section of the manual in which the removal procedure is described.

On the left-hand side of the motorcycle, restrain the pin (13) securing the front of the frame to the engine and unscrew the nut (3) on the right-hand side.

Grease the threads of the clearance adjusters (4) and the ring nuts (5) taking care not to get any grease on face (B) of the clearance adjuster (4).

Tighten to a torque of 0.5 Nm ±10% (Sect. 3 - 3, Frame torque settings) from the outside the clearance adjusters (4) with ring nuts (5) in the frame threaded bushings, until they protrude by about 2 mm on the inside.

Tighten the nut (3) to a torque of 60 Nm ±5% (Sect. 3 - 3, Frame torque settings) while holding the screw (13).

Remove the special screws (6) and tighten the clearance adjusters (4) to a torque of 0.5 Nm ±10% (Sect. 3 - 3, Frame torque settings).

Locate service tool no. 88713.3166 on the ring nut (5) and fit the torque wrench to the tool.

Hold the clearance adjusters (4) and tighten the ring nuts (5) to a torque of 100 Nm ±5% (Sect. 3 - 3, Frame torque settings).

Lubricate thread and underside of special screws (6), then start them on the frame, and tighten them to a torque of 60 Nm ±5% (Sect. 3 - 3, Frame torque settings).

Disconnect all the electrical parts connections from subframe (Sect. 6 - 1, Routing of wiring on frame), and remove the silencers (Sect. 8 - 8, Removal of the exhaust system).

Remove the frame as specified in the previous paragraph “Removal of the frame”.

On the left-hand side of the motorcycle, restrain the pin (13) securing the rear of the subframe to the engine and simultaneously unscrew the nut (3) on the right-hand side.

While holding the nuts (11), present only on the left-hand side of the rear subframe, unscrew the screws (12) and remove the bracket (15).

Remove the cable (A) of exhaust valve motor (B) as explained in Sect. 8 - 8, Removal of the exhaust system.

Unscrew the screws (9) securing the plate (8) and slide out the plate then separate the rear left-hand subframe from the right-hand side one.

Badly damaged frames cannot be repaired, they must be renewed. Any work carried out on the frame can give rise to potential danger, infringing the requirements of EC directives concerning manufacturers' liability and general product safety.

Tighten the screws (9) to the specified torque (Sect. 3 - 3, Frame torque settings), in the sequence: 1-2-3-4.

Connect the cable (A) of exhaust valve motor (B) as explained in Sect. 8 - 8, Refitting the exhaust system.

While holding the nuts (11), present only on the left-hand side, tighten the screws (12) to a torque of 22 Nm ±10% (Sect. 3 - 3, Frame torque settings) in the sequence below: 5-6-7-8.

Refit the rear subframe to the crankcase (Sect. 9 - 1, Refitting the engine).

Reconnect all the electrical parts connectors on subframe (Sect. 6 - 1, Routing of wiring on frame), and refit the silencers
(Sect. 8 - 8, Removal of the exhaust system).

Locate the complete rear subframe assembly on the engine, apply the recommended grease to the threads of the pin (13) and the nut (3).

Tighten the nut (3) to a torque of 60 Nm ±5% (Sect. 3 - 3, Frame torque settings) while holding the screw (13).
