Aprilia SL 750 Shiver 2007–2015 OEM Service Manual (P/N 854146)

• Covers the 2007–2015 Aprilia SL 750 Shiver (854146), detailing maintenance, engine, chassis, and electrical system diagnostics
• Official OEM publication (Part Number 854146)
• Includes 11 technical sections, over 90 torque specification entries, and complex electrical component diagrams
• Formatted as a 303-page indexed PDF, making it fast and easy to find factory settings and component locations for the 750 cc longitudinal V-twin platform
• Outlines step-by-step procedures for valve clearance adjustments, upside-down fork overhauls, hydraulic brake bleeding, timing chain replacements, and clutch plate inspections
• Highlights complex assemblies including the Ride by Wire system, Marelli 5DM ECU, CAN line network, radial brake calipers, throttle bodies, and bank angle sensors

Component and Maintenance Scope

This official service manual outlines the exact technical specifications and maintenance requirements for the Shiver motorcycle line. It provides detailed breakdowns of the 90-degree V-twin engine, multi-disk wet clutch, and 6-speed transmission mechanics. You get a comprehensive chart of service intervals, fluid capacities, and torque-wrench values necessary for proper routine care and repair. Having the exact factory baseline figures allows you to isolate electrical faults at the Marelli ECU on the bench rather than replacing expensive sensors blindly, significantly increasing bay efficiency. Before working with hazardous fluids or heavy engine components, always ensure your workspace meets standard shop safety protocols and wear appropriate gear.

Technical Data Preview

Inside, the engine data section details the M551M engine model. When verifying clearances, it specifies precise ranges at 0.11–0.18 mm for the intake and 0.16–0.23 mm for the exhaust valves. Front fork oil capacity is listed at 535 cm³ per fork tube, while the coolant system requires exactly 1.8 liters. The manual provides strict tightening specs for critical engine assemblies. For instance, the cam cap and head fixing screws require a pre-tightening of 4.90–6.86 Nm followed by a final torque of 9.81–12.75 Nm. When servicing the SL 750, technicians must navigate specific mechanical pitfalls. For example, the rear cylinder camshaft gear utilizes an anticlockwise reverse-threaded nut, and tightening any camshaft gear nut to its final torque while mounted on the cylinder will irretrievably damage the aluminum head. Additionally, the twin throttle grip sensor connectors are identical but strictly non-reversible; failing to verify the banded markers prior to removal will trigger immediate Ride by Wire system faults.

For electrical troubleshooting, you will find complete Wiring diagrams, fuse ratings, and diagnostic codes for the Marelli control unit, supplemented by connector pin-out charts, diagnostic flowcharts, exploded assembly drawings, component layout views, and system routing schematics. The starter relay is located at position 36 on the diagram, the main battery utilizes a 30A fuse, and reference values for the intake pressure sensors sit at 1003–1004 mbar. This data equips technicians with the exact figures needed to troubleshoot efficiently without relying on secondary sources.
