Aprilia Tuono 660 Factory
Every consumable spec for the Aprilia Tuono 660 Factory, each fact sourced, dated, and shown with the source it came from. US-market reference — verify against your owner's manual.
middleweight naked · 2022–present · 659cc 270° parallel twin
Split from aprilia-tuono660 (base bike) for two hardware-distinct facts: Factory-specific final-drive gearing (16T front sprocket vs the base bike's 17T, both 43T rear/520/110-link) and a standard-equipment lithium battery. Every other consumable is shared with the base Tuono 660 via the same 2021 combined RS 660/Tuono 660 OEM manual, which does not itself distinguish the Factory trim. See aprilia-tuono660 for the base Tuono 660 (2021–2024) and its 2025 US-market context.

Trims & editions
- Tuono 660 (base, non-Factory) 2021–present — different final-drive gearing (17T front vs this trim's 16T) and standard lead-acid battery vs this trim's standard lithium pack; has its own sheet (aprilia-tuono660).

Street, track, mixed
Street
- We list the manual's 'with filter change' figure — not the dry-rebuild total that circulates online. On small engines that difference is a 25% overfill.
- 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.

Notes & corrections
Myths corrected
The number that circulates online is wrong. We checked the primary source.
Chain & sprockets: JT's own 'Tuono Factory 660' MY22 catalogue row lists 100 links rather than 110
JT Sprockets Application Guide 2024
Promoted from a conflicts note on the base aprilia-tuono660 sheet (which used the base bike's 17T/110-link row as its primary value and flagged this Factory-specific JT row as unresolved). Verified independently here via Sprocket Center's dedicated 'Aprilia 660 Tuono FACTORY (2022-2025) STOCK SIZES' page, which states 16T front / 43T rear / 520 pitch / 110 links — same link count as the base bike, consistent with only the front sprocket losing one tooth. JT's 100-link figure is treated as the likely error. Verify against the physical chain before cutting a replacement.

Front brake pads: EBC's own catalogue row reads 'RS 660 8V Tuono 2020-2024' and does not split the base Tuono 660 from the Factory trim
TOSPEC research
Same Brembo 4-piston caliper and pad shape as the base bike — clipped the start year to 2022 (this trim's actual launch) rather than assuming the pre-launch 2020-2021 years apply. The 2025 refresh is not yet in EBC's US #304 catalogue.
Rear brake pads: FA266HH is widely advertised by retailers as the RS 660/Tuono 660 rear pad
multiple retailer listings (sportbiketrackgear.com, cbcmoto.com, AP Workshops)
Same gap as the base aprilia-tuono660 sheet. EBC's own US #304 catalogue lists FA266 only under Can-Am/Indian/Zero applications, with no Aprilia RS 660/Tuono 660 row found. Left unverified rather than trusting uncorroborated retailer copy.
Brake fluid: 2025 Factory-only US refresh (52 mm throttle bodies) not yet mapped
TOSPEC research
This manual covers the 2021-2024 launch platform. The 2025 refresh is a documented separate generation on this site and is not independently confirmed to share this spec.
Chain & sprockets: 2026 model year not yet in Sprocket Center's Factory-specific category (capped at 2025)
TOSPEC research
Aprilia's own 2026 Tuono 660 Factory model page states the 2026 bike carries the same specification as 2025, so this is very likely unchanged, but left as a scoping gap rather than assumed.
Battery: The Factory trim ships the BS Battery BSLi-04 lithium pack as STANDARD equipment, not merely as the manual's generic 'alternative solution' framing
Cycle World, Rider Magazine, and Motorcycle.com Factory-trim launch/first-look coverage
Multiple contemporary reviews independently name the lithium battery (~4.4 lb weight saving over a lead-acid unit) as one of the Factory trim's standard differentiators from the base Tuono 660, alongside the fully adjustable fork and standard quickshifter. The manual itself (shared across both trims) frames BSLi-04 lithium as the primary listing with YUASA YTZ10S as an 'alternative solution' without splitting by trim — this fact's encoded value (YTZ10S) is the correct lead-acid cross-reference for either trim; a rider replacing a Factory's stock battery with a lithium-specific charger/maintainer should confirm compatibility rather than assuming lead-acid charging behavior.

Research notes
Context from the research trail — how a fact was pinned down.
Oil spec: This combined manual has one shared 'Tuono 660' Characteristics table and does not distinguish the base bike from the Factory trim
TOSPEC research
Re-cited directly from the same manual used for the base aprilia-tuono660 sheet (aprilia-om-rs660-tuono660-2021) rather than assumed — the manual's fluids/electrical/maintenance tables are not trim-specific, so this value applies to both trims equally. Only gearing and battery differ (see this sheet's chain/battery facts).
Oil filter: HiFlo's HF138 application listing covers the Tuono 660 nameplate as a whole, not trim-specific
TOSPEC research
Same part as the base aprilia-tuono660 sheet — the oil pump/filter housing is shared between trims.
Chain & sprockets: Aprilia's own official 'Tuono 660' technical spec sheet (storeusa.aprilia.com) lists a 17/43 drive ratio
Aprilia USA technical specification PDF (EN_tuono_660.pdf, pdftotext-confirmed)
This spec sheet does not name the Factory trim anywhere and is read as describing the base (non-Factory) bike, matching the base aprilia-tuono660 sheet's 17/43 chain fact. It is NOT used as a source for this Factory-specific 16/43 value; cited here only as corroboration that Aprilia's own generic spec sheet and this trim's dedicated retailer stock-size page genuinely disagree by one front tooth, i.e. this is a real trim difference and not a transcription error.
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.

Aprilia Tuono 660 Factory maintenance FAQ
How much oil does the Aprilia Tuono 660 Factory take?
About 2.7 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 Aprilia Tuono 660 Factory need?
It calls for 10W-50, JASO MA2, API SL. A wet clutch means the JASO class matters — don't substitute an energy-conserving car oil.
What brake pads fit the Aprilia Tuono 660 Factory?
The front caliper (4-piston, 32 mm pistons (Brembo)) 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 Aprilia Tuono 660 Factory need an oil change?
Every 6,200 miles or 12 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.
