Engineered exclusively for the 2025 Yamaha R9, the LighTech TEYA010 chain tensioner sets a new benchmark in drivetrain precision — combining race-proven Ergal 7075 aluminium construction with laser-engraved alignment scales that take the guesswork out of chain setup, whether you are heading to the track or threading through a favourite mountain road.
Key Features
- Fits Yamaha R9 (model year 2025) — a direct, purpose-built replacement for the OEM tensioner
- Machined from solid Ergal 7075 high-strength aluminium alloy for a superior strength-to-weight ratio over the stock component
- Full CNC milling from billet ensures tight tolerances and repeatable accuracy every time you adjust
- External screw adjustment mechanism allows fast, precise chain tension changes without removing the wheel
- Laser-engraved measurement scale delivers millimetre-accurate swingarm alignment — critical for straight tracking under hard acceleration
- Available in black, red, gold and blue anodised finishes to complement your R9 colour scheme
Precision Where It Counts
The standard Yamaha R9 tensioner is adequate for everyday use, but performance riders quickly discover its limitations when chasing exact chain tension on a race weekend or after a tyre swap in the paddock. LighTech addresses this directly with the TEYA010: the external screw adjuster gives you tactile, incremental control, while the laser-engraved scale lets you match left and right alignment to the millimetre — eliminating the shimmy and premature wear that comes from an even slightly crooked rear wheel.
Ergal 7075 — Race-Grade From the Factory
Ergal 7075 is the same high-strength aluminium alloy used in aerospace and top-level motorsport applications. Compared to the more common 6061 alloy, it offers significantly higher tensile strength at a similar weight, meaning the TEYA010 resists the constant tension loads and vibration of a high-revving inline-four without deforming over time. Every tensioner is CNC-milled from a solid billet block, so there are no casting voids or inconsistencies — just clean, dense metal that holds its form lap after lap.
