| Part | Tier | Typical price | Fitment | Add to sheet |
|---|---|---|---|---|
| Exhaust5 fitTermignoni is the factory-adjacent choice (Ducati Performance kits pair with an up-map); SC-Project and Akrapovič are the aftermarket staples. Slip-ons keep the cat and pass as sound mods; decat and full systems commit you to ECU work. | ||||

Why mod a Monster
The Monster invented the naked-bike custom scene in 1993 and the 937 keeps the tradition: it's Ducati's blank canvas, light enough to flatter any rider and plain enough from the factory that a tail tidy and a slip-on visibly transform it. The Rizoma/CNC billet catalog treats the Monster as a first-class citizen.
Monster street mods, in order
Tail tidy
The 937's undertail is tidy by design; the US plate bracket is not. A fender eliminator with integrated signals is the single highest-impact cosmetic dollar on this bike.
Sliders before style
Nakeds get dropped. Frame sliders and engine case protection first — a $200 kit against a four-figure clutch cover repair is easy math.
Billet contact points
Adjustable levers, bar-end mirrors, grips. This is where Monster culture lives — Rizoma bar-end mirrors are practically the model's uniform.
Slip-on for voice
Termignoni (the heritage pick), SC-Project, and Akrapovič all make 937 slip-ons. The cat sits upstream, so a slip-on is sound and looks — that's the honest transaction.
Flash if you decat
Going past the slip-on into cat-delete or full-system territory means ECU work, or the dash lights up and fueling goes lean. Plan the tune with the pipe, not after it.
Suspension for your weight
The base fork is non-adjustable — springs for your weight and a shock upgrade (or SP take-offs) do more for real-road pace than any engine mod on this bike.
Monster track build, in order
Tires and pressures
Stock Rosso III-class rubber is fine for first track days; a Rosso IV or Supercorsa SP step transforms confidence. Learn hot-pressure discipline before buying anything else.
Brake pads, lines, lever guard
Brembo M4.32 monoblocs stock — sintered track pads, fresh fluid, braided lines if original, and the lever guard your org requires.
Fix the fork
The non-adjustable base fork is the bike's track ceiling. Cartridge kits or Monster SP Öhlins take-offs (community-reported to bolt on) plus a quality shock get the chassis to match the brakes.
Ground clearance and ergos
Adjustable rearsets buy cornering clearance the street pegs give away. Tank grips help the braking zones — the Monster's upright position slides you forward.
Protection for the inevitable
Case covers and axle sliders before the fast group. No fairings means the engine cases are the crumple zone.
Gearing experiments
A tooth down front or two up rear sharpens drive out of slow corners — cheap, reversible, and the most 'feels faster' dollar on a torquey twin.
Monster fitment by year (2015–2026)
- Monster 821 (predecessor)2015–2021
Trellis-frame Monster with the 821 cc Testastretta. Nothing structural carries to the 937 — a 'fits Ducati Monster' listing spanning 2015–2023 needs a hard year-and-model check before checkout.
- Monster / Monster+ (937)2021–2025
Clean-sheet redesign: 937 cc Testastretta 11°, aluminum front frame replacing the signature trellis, ~111 hp claimed, up/down quickshifter standard. Monster+ adds the flyscreen and seat cowl — same fitment otherwise.
- Monster SP2023–2025
Öhlins suspension, Brembo Stylema calipers, Termignoni silencer, lithium battery from the factory. The SP spec sheet reads like the base bike's upgrade shopping list — useful as a build blueprint.
- Monster (890 V2)2026+
New Monster on Ducati's 890 cc spring-valve V2. A separate platform — expect near-zero carryover from the 937. Confirm generation before buying anything sold as 'new Monster' fitment.
Monster gotchas — read before buying
Monster parts interchange
Reported by riders; verify before buying. Full chart →
- Community-reported: the 937 Testastretta 11° is shared with the SuperSport 950, Hypermotard 950, and Multistrada V2 — engine-side items like case protection, filters, and some service parts cross between them. Chassis and bodywork do not.
- Community-reported: Monster SP Öhlins suspension and Stylema-caliper take-offs bolt onto the base 937, making SP take-off shopping a known upgrade path on owner forums.
Ducati Monster mods FAQ
Will Monster 821 parts fit the 2021+ Monster?
Almost never. The 2021 redesign replaced the trellis frame with an aluminum front frame and changed the engine to the 937 Testastretta — bodywork, subframe, exhaust, and most bolt-ons are incompatible. Only verify-per-part generic items (levers, some grips) cross.
Does a slip-on on the Monster 937 need a tune?
No — the cat stays with a slip-on and the stock map copes fine. A decat pipe or full system is different: plan on an up-map or independent flash, or expect lean fueling and a dash warning.
Does the Monster 937 have a quickshifter?
Yes — up/down quickshift is standard equipment on the 937 Monster (2021+). There's nothing to add; check it's working properly on used bikes instead.
Can I do track days on a Monster 937?
Absolutely — it's light, the Brembo M4.32 brakes are genuinely good, and the riding position builds confidence. The honest limits are the non-adjustable base fork and ground clearance; springs for your weight and adjustable rearsets address both.
Is the Monster SP worth it over the base Monster?
If you'd buy Öhlins suspension and better brakes anyway, the SP bundles them cheaper than doing it aftermarket. If your riding is city-and-Sunday, the base bike plus a tail tidy, sliders, and springs for your weight covers what you'll actually feel.
