Oil capacities are the manufacturer's with-filter-change figure, not the dry-rebuild total that circulates online. Always verify against your own owner's manual before you turn a wrench — this is educational reference, not a repair procedure.

Street, track, mixed
Street
- Pads fit calipers, not bikes. That's why one shape number covers a Hayabusa and a V-Strom — and why the same bike model can change shape mid-generation. We resolve pads by caliper and year.
Track
- After track days, shorten your oil change. How much is genuinely unsettled — manufacturers say 'adjust to your use,' not a number. Used-oil analysis is the only rigorous answer.
- A street-legal sintered or EPFA-class pad is the manufacturer-sanctioned track-day choice. Full race compounds are for when the pad is the limiting factor — and yours isn't yet.
- RBF-class fluid buys you ~80°C more fade margin when fresh — and gives most of it back within a year as it absorbs moisture. It's a consumable you change more often, not an upgrade you install once.
- For the street: silicate-free motorcycle coolant (Honda's manuals explain why — silicates chew water-pump seals). For the track: check your org's rules — most ban ethylene glycol outright; pro racing allows water only.
Mixed
Run the street specs above, then shorten the oil interval after track days — how much is genuinely unsettled, so used-oil analysis is the honest guide. If your organisation tech-inspects coolant, check its rules before a session.
Maintenance jobs & what they cost
Oil & filter change
Beginner-safeParts — Oil spec JASO MA2 · API SN · Viscosity 15W-50 · Oil capacity with filter 3.1 L · drain not published · dry total not published · Oil filter OEM 44440034A · HiFlo HF153
Tools — torque wrench, oil filter wrench, drain pan, funnel, new sealing washer (if your bike uses one)
Dealer oil-change quotes run $90–130 (Harley outliers $180–280 excluded); independent-shop average is closer to $56. DIY consumables run $30–60, saving roughly $40–120 per change with tooling paid back in 2–3 changes. Sourced: CostHack / Trak Powersports / J.D.

Notes & corrections
Coverage gaps
Where the catalogues run out. Flagged in the open, never guessed at.
Oil capacity: Drain-only and dry-total figures are unpublished
TOSPEC research
The owner's manual gives only the combined sump+filter figure; do not invent a drain-only number.
Air filter: 2025 unattested
TOSPEC research
fill in a later wave.
Spark plugs: NGK's EU part-finder has no 'Monster 937' model entry
ngkntk.com
The OEM manual is the source of record here. Gap not published; count 2 inferred from the twin-cylinder architecture (one plug per cylinder).
Front brake pads: Monster SP (2023–2025) has its own sheet
TOSPEC research
Different front caliper (Stylema-family M4.30 → EBC FA447HH, not this bike's FA630HH). Do not fit FA630HH to an SP. See ducati-monster-sp for the SP's pads_front fact and full sourcing.
Front brake pads: 2025 not listed in cat #304
TOSPEC research
fill in a later wave.
Rear brake pads: 2025 not listed in cat #304
TOSPEC research
fill in a later wave.
Battery: Monster SP (2023–2025) has its own sheet
TOSPEC research
The SP ships a factory lithium battery (SKY/Skyrich HJT7B-FPZ-SCR, 12V 4Ah), not this bike's lead-acid YT7B-BS — a different charge maintainer is required. See ducati-monster-sp for the SP's battery fact and full sourcing.
Research notes
Context from the research trail — how a fact was pinned down.
Oil spec: UK-market note names the product 'Shell Advance DUCATI 15W-50 Fully Synthetic Oil'
ducati-om-monster937-my21
Same 15W-50 / JASO MA2 / API SN spec; regional Shell marketing name only.
Viscosity: single fixed grade — no temperature/alternate-viscosity chart in these manuals
TOSPEC research
Oil filter: OEM suffix revisions circulate (44440034A/35A/37A/38A/39A)
retail listings
Long-lived Ducati cartridge shared across decades of models; HiFlo's cross-ref 444.4.003.4A used here. Exact current-revision suffix unpinned — same HF153 cartridge regardless.
Air filter: HiFlo does not catalogue an HFA air filter for the 937
hiflofiltro.com
Front brake pads: Some online FA630HH fitment mirrors omit the Monster 937
RevZilla EBC fitment mirror
EBC catalogue #304 does list Monster Plus 2021–2024 → FA630HH; the omission looks like stale mirror data. Recorded for transparency.
Rear brake pads: Rear shape is identical across base/Plus and SP trims
ebc-us-304
Both rows carry FA266HH — the trim split applies to the front only.
Chain & sprockets: Ducati recommends replacing the drive chain kit within 20,000 km/12,000 mi
Ducati scheduled maintenance chart
Maintenance recommendation, not a fitment split.
Service intervals: MY21 edition states no explicit month cap on the Oil Service
ducati-om-monster937-my21
The 24-month cap appears in the 2023 SP edition; both editions also define a separate 12-month Annual Service checklist (different items, not an oil change).
Service intervals: Desmo Service is 30,000 km/18,000 mi — longer than the V4 family's 24,000 km
TOSPEC research
The Testastretta 11° is desmodromic (both manuals + ducati.com Testastretta page) — an earlier 'spring-valve, shorter interval' assumption was wrong; the 30,000 km figure is the manuals' own.
DIY & your warranty
Doing this yourself won't void your factory warranty. The federal Magnuson-Moss Warranty Act bars a manufacturer or dealer from voiding your warranty just because you — not the dealer — did routine maintenance. To deny a claim they must prove the specific work caused the specific defect. Use spec-compliant parts and fluids, and keep your receipts.

Ducati Monster (937) maintenance FAQ
How much oil does the Ducati Monster (937) take?
About 3.1 litres with a filter change — the manufacturer's with-filter figure, not the larger dry-rebuild number that circulates online. Confirm against your owner's manual.
What oil does the Ducati Monster (937) need?
It calls for 15W-50, JASO MA2, API SN. A wet clutch means the JASO class matters — don't substitute an energy-conserving car oil.
What brake pads fit the Ducati Monster (937)?
The front caliper (Brembo M4.32 monobloc 4-pot radial) takes EBC shape FA630HH. Pads are resolved by caliper and year, not by model name, so verify your caliper before you order.
How often does the Ducati Monster (937) need an oil change?
Every 9,000 miles or 24 months, whichever comes first, per the manufacturer's schedule. Shorten it after track days — used-oil analysis is the only rigorous answer to how much.
