Whether you use the bike on track days or simply want a machine that performs and sounds like a works racer, this kit is engineered to deliver exactly that without compromise.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignificant weight reduction of 6.2 kg compared to the stock exhaust system (SC-Project unit weighs just 1.8 kg versus 8 kg OEM)\u003c\/li\u003e\n\u003cli\u003eTitanium de-cat link pipe maximises exhaust flow and throttle response while eliminating catalytic restriction\u003c\/li\u003e\n\u003cli\u003eØ70 mm outlet diameter produces a pure, unfiltered racing sound at 123 dB at 6,500 rpm — no dB killer fitted\u003c\/li\u003e\n\u003cli\u003eAvailable in two premium finishes: Titanium version (Y11C-DET70T) with laser-etched SC-Project logo, and Carbon version (Y11C-DET70C) with riveted SC-Project plaque as seen on factory race machines\u003c\/li\u003e\n\u003cli\u003eCNC-machined sleeves and hand-finished T.I.G.-welded titanium joints for precision fit and long-term durability\u003c\/li\u003e\n\u003cli\u003eCompatible with the original pillion footpegs and prepared for the OEM lambda sensor connection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance and Build Quality\u003c\/h2\u003e\u003cp\u003eSC-Project developed the GP70-R drawing directly on their MotoGP programme. The retro-inspired canister shape houses a straight-through race core, and the Ø70 mm exit diameter is tuned for the deep, aggressive acoustic signature that has become SC-Project's trademark on the world stage. Removing 6.2 kg from the rear of the machine noticeably sharpens handling and reduces unsprung mass, with improved throttle pick-up felt immediately on first ride.\u003c\/p\u003e\u003cp\u003eEvery weld on the titanium link pipe is completed by hand using the T.I.G. process, and the CNC-machined sleeves ensure a rattle-free, leak-free fitment that holds up across repeated heat cycles on track. The titanium construction offers outstanding resistance to the extreme temperatures generated by the R1's crossplane four-cylinder, making this a genuine long-term investment rather than a short-term upgrade.\u003c\/p\u003e\u003ch2\u003eTwo Versions, One Standard of Finish\u003c\/h2\u003e\u003cp\u003eThe Titanium version (Y11C-DET70T) features a laser-etched SC-Project logo that catches the light cleanly and ages beautifully with heat patination. The Carbon version (Y11C-DET70C) uses a woven carbon fibre sleeve secured with rivets and an SC-Project plaque, replicating the specification seen on SC-Project's factory-supported MotoGP entries. Both versions ship with the same titanium de-cat link pipe and identical performance characteristics — the choice is purely aesthetic.\u003c\/p\u003e\u003cp\u003ePlease note: current product images show the earlier RN49 generation.

It is not road-legal and is intended for closed-circuit racing and track use only. The lambda sensor bung is retained for ECU compatibility, and the mounting points are fully compatible with the standard pillion footpeg brackets, so no additional modifications to the subframe are required for installation.\u003c\/p\u003e\u003ch2\u003eImportant Notice\u003c\/h2\u003e\u003cp\u003eThis exhaust system does not hold road-type approval and must only be used in a closed racing environment (FOR RACING USE ONLY).
