DescriptionThe whole story▼
Precision-engineered from the same materials trusted on world championship grids, the LighTech TEYA005 chain tensioner brings genuine race-derived craftsmanship to the Yamaha YZF-R1 and R1M RN65. Every surface tells the story of CNC-milled Ergal 7075 aluminium — a material chosen not for cost but for its exceptional strength-to-weight ratio — finished in your choice of anodised colour to complement the R1's striking aesthetics.
Key Features
- Fits Yamaha YZF-R1 and YZF-R1M RN65, model years 2020 through 2026 — a direct, precision replacement that slots in without modification
- Machined from solid Ergal 7075 billet aluminium, delivering outstanding rigidity under the high chain loads generated by the R1's crossplane inline-four
- External adjuster screw allows fast, tool-friendly chain tension fine-tuning — no need to remove components between sessions
- Laser-engraved scale on each arm makes it straightforward to align both sides identically, ensuring the wheel runs true and chain wear is even
- Available in anodised black, red, blue, or gold — four finishes that integrate cleanly with factory and aftermarket R1 colour schemes
- Expandable with the optional fork kit FTEYA005 for a fully matched LighTech drivetrain setup
Design, Finish and Heritage
LighTech has spent decades supplying components to race teams who cannot afford failure, and that uncompromising philosophy is visible in the TEYA005 the moment you pick it up. The hard anodised finish is not purely aesthetic — it adds a layer of surface hardness that resists the abrasion and oil contamination inevitable in chain-drive environments. The laser-engraved graduation markings are recessed into the metal rather than painted on, so they remain legible after seasons of track and road use. Compared with the factory stamped-steel units, the difference in quality of feel and finish is immediate and unmistakable.
Performance on Track and Road
Correct chain tension is one of the most frequently overlooked elements of motorcycle setup, yet it directly affects rear suspension behaviour, sprocket wear and power delivery feel. The TEYA005's external adjustment screw lets you dial in tension at the trackside without the fuss of loosening multiple fasteners, which is particularly valuable during timed practice sessions when every minute counts. The laser scale takes the guesswork out of maintaining equal adjustment on both sides — a critical point, because unequal tension shifts the rear axle out of square and introduces handling inconsistencies that are difficult to diagnose. For road riders, the same precision means longer chain and sprocket life and more predictable throttle response at any speed.
Fitment and Compatibility
The LighTech TEYA005 is designed specifically for the Yamaha YZF-R1 and YZF-R1M in the RN65 generation, covering model years 2020 to 2026. It is not a universal part — the geometry and mounting points are matched precisely to this chassis. If you wish to extend the upgrade, the optional fork kit FTEYA005 is available separately from Inter-Pace.
