LighTech Chain Tensioner for Yamaha YZF-R1 RN22 (2009–2014) TEYA004

Keeping your Yamaha YZF-R1 RN22 in perfect adjustment has never been more straightforward. The LighTech TEYA004 chain tensioner brings CNC-machined Ergal 7075 aluminium precision to everyday maintenance, making chain tension checks and corrections a quick, accurate job whether you are prepping for a trackday or setting off on a Sunday ride.

Key Features

• CNC-machined from Ergal 7075 high-strength aluminium alloy — lightweight, durable and fully race-grade
• External screw adjustment lets you dial in chain tension precisely without removing bodywork or reaching into awkward spaces
• Laser-engraved scale on both sides ensures perfectly symmetrical alignment, eliminating uneven chain wear at a glance
• Direct bolt-on fitment for Yamaha YZF-R1 RN22 (2009–2014) — no modifications required
• Available in four anodised colours to complement your R1's livery
• Compatible with the optional fork kit FTEYA004 for a complete rear-end upgrade

Everyday Usability Meets Race-Derived Engineering

The TEYA004 is built around the same principle that makes LighTech components popular with club racers and road riders alike: sophisticated engineering that simplifies the job. The external adjuster screw means you no longer need to estimate tension by feel alone. Turn the screw, read the laser scale, match both sides — done. That consistency protects your chain, sprockets and wheel bearings from the kind of quiet, cumulative damage that comes from running even slightly off-centre alignment.

Ergal 7075 is the material of choice when strength-to-weight ratio matters most. It is appreciably stiffer and stronger than standard 6061 aluminium yet adds virtually no weight penalty over the stock tensioner. The CNC machining process holds tight tolerances throughout, so threads engage cleanly and the adjuster moves smoothly every time.

Track Compatibility

For riders who take the R1 to circuit days, the laser scale becomes genuinely useful in the paddock. Rapid chain checks between sessions can be completed in moments, and the clear graduations make it easy to return to a known setting after swapping a wheel. Pair the TEYA004 with the optional LighTech fork kit FTEYA004 to round out the rear-end upgrade with matching quality and aesthetics.
