Double welded stainless steel front collector – Triumph Speed Twin 1200 / Thruxton

Optimized flow, reinforced torque, released sound and careful finishes for your twin-cylinder

Unlock your engine's potential with this stainless steel front manifold designed for Triumphs SpeedTwin 1200 and Thruxton 1200. Its design straight-through high flow rate drastically reduces the original restrictions in order to improve the breathing of the twin, for a best filling, a sharper ramp-up and a driving pleasure significantly reinforced.

Machined in a thick and durable 304 stainless steel, this collector benefits from TIG welding precise and regular. Smoothed internal sections help maintain high gas velocity, while neat curves reduce turbulence. The result: a more lively response to the handle, a lower torque available and a deepest sound, sporty without being aggressive. The locations for lambda probes are designed to maintain the original functionalities.

Two variants are offered to match your motorcycle exactly: Version 1 for Speed Twin 1200 until the 2025 model year and Thruxton 1200 ; Version 2 for the Speed Twin 1200 from model year 2026. Simply choose the version suited to your model year for a no-surprise fitment and perfect alignment with the rest of the line.

Compatibility:

• Triumph Speed Twin 1200 (until 2025) – Version 1

• Triumph Thruxton 1200 – Version 1

• Triumph Speed Twin 1200 (from 2026) – Version 2

Technical specifications:

• 🛠 Type: 2-into-2 “straight-through” high-flow front manifold, reduced restriction section

• 📏 Dimensions: approximate inlet diameter 45mm, junctions ~48mm, tube thickness ~1.2mm

• 💪 Material: Corrosion and heat resistant 304 stainless steel

• 🧵 Welding: TIG process with double reinforcement cord for increased reliability

• 🌡 Thermal management: optimized trajectories to limit heat accumulation and improve gas evacuation

• 🧪 Lambda probes: pre-equipped to retain the original electronic management

• 🎨 Finish: brushed stainless steel appearance with visible quality welds

• ⚖️ Indicative weight: approx. 2.8 kg (variable depending on version)

• ⚠️ Note: dedicated to performance optimization; approval may vary depending on local regulations

Advantages compared to the origin:

✔ Reduced pressure losses for a higher exhaust gas flow
✔ Livelier engine response and increased mid-range torque
✔ Deeper and sportier sound while remaining controlled
✔ Durable 304 stainless steel, resistant to corrosion and high temperatures
✔ Precision TIG welding for maximum longevity
✔ Integration of lambda probes for perfect electronic compatibility
✔ Precise fit to original mounting points
✔ Two variants for exact fitment depending on the year of Speed Twin

Why improve the original part?

Stock manifolds are often designed to prioritize comfort and compliance, resulting in internal restrictions, a higher weight and one muffled sound. In use, this can impact the liveliness of the engine and restrict the character of the Triumph twin-cylinder.

• Loss of flow linked to baffles and narrowed sections

• Greater temperature rise under the engine

• Its too discreet and lacks presence

• Increased inertia due to heavy construction

This performance collector corrects these limitations: the high flow internal layout and the304 stainless steel improve the breathing, reduce the concentrated heat and release a sound signature more authentic, while retaining theoriginal integration and sensor compatibility.

Ideal use:

• Muscular roadster preparation on Speed Twin 1200 for more torque and character

• Café racer project based on Thruxton 1200 seeking a pure look and a refined soundtrack

• Performance optimization with adapted mapping and conservation of lambda probes

• Track or track-day use requiring better gas evacuation

• Everyday riders wanting more responsive response without sacrificing reliability

Choice of version: select Version 1 if your motorcycle is a Speed Twin 1200 (until 2025) or a Thruxton 1200; opt for Version 2 if your Speed Twin 1200 is from model year 2026. If in doubt, check the model year of your machine before ordering.
