Weighing just 4.5 kg across the complete system, it strips meaningful mass from the stock setup, sharpens throttle response and delivers the crisp, purposeful exhaust note the crossplane R1 deserves — all with a removable dB killer that lets you dial in the noise level to suit the day.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eComplete titanium system weighing only 4.5 kg — a direct reduction over the heavy OEM setup for improved handling and agility\u003c\/li\u003e\n\u003cli\u003eTitanium header and silencer body with carbon end cap — an excellent combination of heat resistance, minimal weight and long service life\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer included — straightforward to fit or remove depending on circuit regulations or personal preference\u003c\/li\u003e\n\u003cli\u003e350 mm silencer length with a 58 mm outlet diameter — proven Competition EVO dimensions for optimal flow on the YZF-R1 platform\u003c\/li\u003e\n\u003cli\u003eRace-use specification engineering — developed specifically to deliver peak power and optimised throttle response under demanding track conditions\u003c\/li\u003e\n\u003cli\u003eDirect, hassle-free fitment on all Yamaha YZF-R1 and YZF-R1M model years 2017 through to 2026\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality \u0026amp; Materials\u003c\/h2\u003e\u003cp\u003eArrow has built the 71211CKZ around an all-titanium construction throughout — header, silencer shell and internal components alike. Titanium offers an outstanding strength-to-weight ratio and copes effortlessly with the extreme heat cycling a high-revving four-cylinder generates lap after lap. The carbon end cap adds a further reduction in rotational mass at the tail of the system while giving the whole package a purposefully race-bred appearance. These are not decorative choices; every material decision in the Competition EVO line is driven by function.\u003c\/p\u003e\u003ch2\u003eTrack Performance\u003c\/h2\u003e\u003cp\u003eThe Competition EVO designation sits at the top of Arrow's race-oriented catalogue. The system is engineered to maximise power output and sharpen throttle pick-up compared to the standard exhaust, particularly in the mid-to-upper rev range where the YZF-R1 crossplane engine does its best work. Arrow recommends a custom ECU remap to unlock the full potential of the system; without remapping, the gains are still appreciable, but a dedicated map will extract every last fraction of performance the new flow characteristics make possible.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe Arrow 71211CKZ is a direct-fit complete exhaust system designed exclusively for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 (2017–2026)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M (2017–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNo additional adaptors or modifications are required for installation on the above models.\u003c\/p\u003e\u003ch2\u003eImportant Notice\u003c\/h2\u003e\u003cp\u003eThis exhaust system carries a race-use only homologation.
