This official 148-page Aprilia publication (P/N 9100650, first edition June 2006) serves as the primary technical reference for 2006–2013 SXV 450, RXV 450, SXV 550, and RXV 550 twin-cylinder motorcycles. Designed specifically for professional technicians and experienced mechanics, it details the core mechanical parameters for engine, lubrication, and transmission servicing throughout the production life of the 45SX, 45RX, 55SX, and 55RX engine builds.

• Contains 47 high-detail engine component breakdown photos
• Provides 15 complete torque-setting specification tables
• Includes 26 specialized factory tool identification listings

Engine Service and Component Walkthrough

This documentation breaks down the exact specifications needed to maintain and assemble the 450 and 550 series engines. It highlights essential mechanical overviews, offering complete outlines for engine removal, water pump servicing, and cylinder head teardowns. Inside, you will find authoritative reference material covering camshaft and rocker arm assembly, piston maintenance, and clutch pack replacement. The layout is structured logically. Mechanics can quickly locate critical reference data for timing chain tensioner inspections or lubrication system diagnostics.

Technical Specifications and Calibration Data

Engine performance data is heavily documented for all model variants. This includes compression ratios, valve timing angles, and gear ratios. The publication features extensive torque settings for critical engine components like the primary shaft, head bolts, and crankshaft bearings. A specialized section details the use of the Axone tool. This allows technicians to read engine parameters, manage ECU mapping, and troubleshoot error codes. Intake valve clearances for the 450 and 550 series are specified at 0.07–0.12 mm. Additionally, engine oil capacity for periodic changes is documented at 1300 cc. Crankcase class markings for bearing selection are explicitly detailed for precise component matching. Operating on high-performance motorcycles carries inherent physical risks. Mechanics must strictly follow standard shop safety protocols and verify all specifications prior to starting heavy engine teardowns.
