Used OEM parts for the Ducati Monster 937 are available at Sun Coast Cycle Sports. Introduced in 2021, the Monster 937 (officially marketed simply as "Monster") is the current-generation Monster, replacing the Monster 821 with a larger 937cc Testastretta 11-degree liquid-cooled L-twin engine. The 937 marked a dramatic chassis redesign, replacing the traditional steel trellis frame with an aluminum monocoque front frame that uses the engine as a stressed member, paired with a polymer trellis rear subframe. Despite the radical engineering changes, the Monster 937 retains the stripped-down naked bike character that has defined the Monster line since 1993. All parts are individually inspected, photographed, and shipped from Florida.
Monster 937 generation and parts compatibility
The Monster 937 has been produced since 2021 with the same fundamental architecture. The 937cc Testastretta 11-degree engine is shared with the Multistrada 950/V2, Hypermotard 950, and SuperSport 950, so engine internals cross over between these platforms. However, the Monster 937's aluminum front frame, polymer rear subframe, and bodywork are unique to this model.
The Monster 937 does not share its frame or bodywork with any prior Monster generation. The steel trellis frame used on every previous Monster from 1993 through 2020 was replaced entirely. The 937's engine is also a different displacement from the Monster 821's 821cc unit, so engine internals do not cross over between the two despite both using the Testastretta architecture.
Kawasaki offered a Monster 937+ (with additional electronics and Ohlins suspension) alongside the base Monster. Both share the same engine and core chassis, differing in suspension specification, electronics, and trim. Parts interchange between the base and + models for engine and most chassis components.
Common Monster 937 failure points and replacement parts
Desmodromic valve service: The Testastretta engine uses Ducati's Desmodromic valve system with recommended service at 18,000 miles. Valve shim kits, cam belt kits, and gasket sets are essential maintenance items. The liquid-cooled Testastretta design extends service intervals compared to older air-cooled Monsters.
Crash damage: The Monster 937's naked design exposes the aluminum frame, engine, and tank to direct contact during tip-overs. Frame sliders are a popular addition, and engine covers, tank panels, and bodywork are common replacement items after drops.
Electronics complexity: The Monster 937's comprehensive electronics suite (cornering ABS, traction control, wheelie control, riding modes, quickshifter, TFT display with Bluetooth) relies on numerous sensors. Lean angle sensors, wheel speed sensors, and quickshifter components can develop faults. ECU and sensor replacements are periodic parts requests on higher-mileage machines.
Chain and sprocket wear: The 937's 111 horsepower output accelerates chain and sprocket wear compared to lower-powered Monsters. Chain and sprocket sets are routine maintenance items.
Wet clutch maintenance: The hydraulically actuated wet slipper clutch requires periodic plate and fluid replacement. Clutch plate kits are common service items, particularly on machines used in urban stop-and-go traffic.

Frequently asked questions
Q: Does the Monster 937 share its engine with other Ducati models?
Yes. The 937cc Testastretta 11-degree engine is shared with the Multistrada 950/V2, Hypermotard 950, and SuperSport 950. Engine internals cross over between these platforms, giving parts buyers multiple potential donor sources. Exhaust, ECU calibration, and chassis components are model-specific.
Q: Does the Monster 937 share parts with the Monster 821?
No. The Monster 937 has a different displacement engine (937cc vs. 821cc), entirely different frame (aluminum monocoque vs. steel trellis), and different bodywork. These are fundamentally different platforms despite both being "Monsters."
Q: Is the Monster 937 the same as the "Ducati Monster" (2021+)?
Yes. Ducati markets the current model simply as "Monster" without a displacement suffix in most markets. It is commonly referred to as the Monster 937 to distinguish it from the many prior Monster generations. The engine displaces 937cc.
