DescriptionThe whole story▼

Aerospace-grade titanium and high-end carbon construction set the SC-Project CR-T apart from every other slip-on on the market. Developed directly from SC-Project's Moto2 and MotoGP programmes, this system for the Yamaha YZF-R1/M RN65 (2020–2026) strips 6.25 kg from the stock exhaust package while delivering the unmistakable crack and roar of a full factory race machine.

Key Features

  • Massive weight saving of 6.25 kg — SC-Project system weighs just 1.75 kg versus the 8 kg OEM unit
  • T.I.G.-welded titanium sleeves and CNC-machined connections for race-grade precision and longevity
  • Titanium de-cat link pipe included, eliminating back-pressure for unrestricted flow to the silencer
  • Titanium flame mesh end-cap delivers an authentic MotoGP visual signature
  • 70 mm diameter outlet generates 123 dB at 6,500 rpm without a dB-killer fitted
  • Lambda sensor port retained for seamless ECU mapping compatibility
  • Pillion footpeg mounts remain fully compatible — no bracket modifications required

Aerospace Materials, Handcrafted Precision

SC-Project builds the CR-T from the same material palette used on their championship-winning race bikes. The titanium variant (Y11C-DET36TR) features an iridescent heat-treated finish that deepens with use, while the carbon variant (Y11C-DET36CR) uses high-temperature-coated carbon fibre for a sharp, track-focused aesthetic. Every weld is carried out by hand using the T.I.G. process, and all mating surfaces are CNC-machined to guarantee a rattle-free, zero-compromise fit on the RN65 frame.

MotoGP Sound, Road-to-Race Performance

Remove the de-cat link pipe from the equation and you already notice the change in throttle response. Pair it with the CR-T silencer and the Yamaha R1's crossplane inline-four takes on an entirely different character — sharper, more immediate, with an aggressive exhaust note at 123 dB (no dB-killer) that leaves nothing in reserve. Optimised internal gas flow improves throttle pick-up across the rev range, making the system as effective on track as it is visually arresting in the paddock.

Note: Product images currently show the RN49 generation. Updated RN65-specific images are coming soon.
