Rooted in K-Tech's proven motorsport heritage, its clean anodised finish and precise machined construction mark it out as a component built to a higher standard — one that rewards riders who demand both aesthetic quality and genuine dynamic performance from their suspension.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e12-click compression damping adjustment for precise tuning across a wide range of road and track conditions\u003c\/li\u003e\n\u003cli\u003e10-click rebound damping adjustment for controlled, confident handling through fast direction changes\u003c\/li\u003e\n\u003cli\u003eAdjustable spring preload to dial in the correct ride height and balance for rider weight and riding style\u003c\/li\u003e\n\u003cli\u003eLength adjustment (RCU travel: 4.00 mm) allows fine-tuning of chassis geometry\u003c\/li\u003e\n\u003cli\u003eNitrogen (N2) charged internals deliver consistent damping performance and eliminate aeration foam\u003c\/li\u003e\n\u003cli\u003e46-150-160 spring specification ensures enhanced traction and stability under hard acceleration and braking\u003c\/li\u003e\n\u003cli\u003eDirect OEM-compatible fitment — straightforward installation with no modifications required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eK-Tech Suspension has built its reputation supplying shock absorbers and fork cartridges to professional race teams across British Superbikes, World Supersport, and the Isle of Man TT. That competition-derived knowledge feeds directly into the RAZOR-R range. The unit's housing carries K-Tech's characteristic clean machined appearance — a component that looks as purposeful as it performs, complementing the RS 660's sharp bodywork without compromise.\u003c\/p\u003e\u003cp\u003eThe 35.00 mm RCU housing diameter and 14.00 mm shaft are dimensioned for the RS 660's specific rear linkage geometry. Upper and lower eye mounts measure 23.00 mm wide with a 10.00 mm bolt diameter at each end, matching the factory mounting hardware precisely. A nitrogen charge at 10.00 bar keeps the oil-gas interface stable under sustained load, whether the bike is being ridden hard on a Sunday morning road route or pushed through a track day session.\u003c\/p\u003e\u003ch2\u003eOn-Road and Track Performance\u003c\/h2\u003e\u003cp\u003eThe RAZOR-R's 22-click combined adjustment range — 12 clicks of compression, 10 of rebound — gives riders a genuinely wide tuning envelope. A spring preload of 5 mm is set from the factory, with the 46-150-160 spring (spring rate 160 N) delivering a firm yet compliant platform that suits the RS 660's mid-weight chassis. The 55.00 mm stroke and overall length of 308.00 mm (adjustable within a -1 mm \/ +9 mm tolerance) replicate the OEM travel envelope while providing the resolution to improve on stock damping characteristics at both ends of the speed range.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe K-Tech RAZOR-R shock absorber part number 279S-020-010-011 is a direct fitment for the following motorcycle:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eAprilia RS 660 — model years 2020 to 2026\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation Note\u003c\/h2\u003e\u003cp\u003eInstallation should be carried out exclusively by an authorised K-Tech Service Centre.
