2003–2006 Ducati 749S Biposto/Monoposto Parts Catalog (P/N 915.1.178.1A)

Ducati 749S parts catalog for 2003–2006 biposto and monoposto models, P/N 915.1.178.1A, originally issued October 2002. This is a parts-identification reference, not a step-by-step repair manual.

Searchable Parts Lists and PDF Contents

Text search and navigation: Parts descriptions, part numbers, and the numerical index are searchable. No embedded PDF bookmarks are included; the contents page and part-number index provide references to the catalog drawings.

One printable 176-page PDF contains 161 numbered catalog pages, a 10-page part-number index, and five additional pages: one cover, one publication-label sheet, and three blank pages, all included in the total. Parts descriptions appear in English, Italian, French, German, and Spanish.

Engine, Chassis and Electrical Parts Breakdowns

These highlights are a selection of catalog content. Other entries include paint references and side-stand components.

• Engine internals: Exploded views and parts lists for the crankshaft, cylinders, pistons, half-crankcases, valve timing components, oil pump, and filters.

• Clutch and gearbox: Illustrated identification of the clutch drum, plate set, control components, gearbox shafts, individual gears, and gearchange mechanism.

• Fuel, cooling and exhaust: Component drawings for the throttle body, fuel delivery and return connections, cooling circuit, radiators, and exhaust system.

• Chassis and brakes: Parts breakdowns for the front fork, rear suspension, swingarm, hydraulic brakes, wheels, and variant-specific rear frames.

• Electrical components: Front and main wiring-harness illustrations, battery box mount, injection control unit, starter components, and headlight and instrument-panel assemblies.

• Workshop equipment: Illustrated listings for special tools and the Mathesis diagnosis tester, including its cables, adapters, sensors, and memory cards.

This catalog is suited to owners and parts staff who can identify assemblies from exploded views and match numbered callouts to parts-list entries.

Matching Drawings to a Parts Order

Numbered component illustrations pair with parts lists giving code numbers, descriptions, and quantities. The numerical index links a known part number back to its drawing and position, supporting both visual identification and checks of an existing parts list.

The general information specifies the details needed for an order, including the part code, description, quantity, and motorcycle serial number. The illustrations show component relationships; they do not establish a repair sequence or replace workshop instructions.

Valve-train detail: Separate opening- and closing-shim tables associate available sizes with individual part numbers. The head listings also distinguish valve guides, valve seats, rocker arms, and shafts. These are parts-selection references rather than valve-clearance specifications or adjustment procedures.

Biposto, Monoposto and Bodywork Differences

Separate rear-frame drawings distinguish the biposto and monoposto arrangements. The rear-suspension list also assigns different part numbers to their shock absorbers, allowing those variants to be distinguished before ordering.

Seat and tail-section drawings separate single-seat and passenger-seat components. Bodywork lists distinguish red, yellow, and selected unpainted panels, including the headlight fairing and upper and lower fairing sections.

Harness Illustrations and Special-Tool Listings

The front-wiring and injection-system drawings identify harness assemblies and associated electrical parts. These are component and routing illustrations, not circuit schematics with pin assignments or electrical fault-finding procedures.

The workshop-tool section identifies equipment such as clutch-holding tools, rocker-shaft extractors, and Showa fork tools. For example, tool 88713.1096 is listed for fitting the fork seal ring. The Mathesis section identifies diagnostic equipment and accessories; it does not provide tester operating instructions or diagnostic routines.

Safety note: Use the catalog for parts identification. Verify repair procedures and safety requirements with a qualified technician before servicing engine, brake, or suspension assemblies.

Selected Final-Drive Parts Details

The gearbox parts list identifies front sprocket 449.1.045.1A with rubber protection and 15 teeth. The wheel assembly list identifies rear sprocket 494.1.082.1A with 39 teeth. These entries connect a component specification to its ordering number; they are catalog configurations, not recommendations for changing the gearing.
