Machined from solid Ergal 7075 aerospace-grade aluminium, the LighTech TETR003 chain tensioner is a definitive upgrade over the factory unit for Triumph Street Triple 765 R and RS riders who demand precision and longevity from every component on their machine.
Key Features
- CNC-machined from solid Ergal 7075 billet aluminium — superior rigidity and dimensional accuracy over cast OEM parts
- External adjustment screw for fast, precise chain tension setting without removing components
- Laser-engraved scale on both sides ensures perfect wheel alignment at a glance
- Reduces drivetrain wear by maintaining consistent, accurate chain tension across varied riding conditions
- A direct, no-compromise fitment for Triumph Street Triple 765 R and RS (model years 2023–2026)
Built to a Higher Standard
Ergal 7075 is the same high-strength aluminium alloy used in aerospace and professional motorsport applications. LighTech chose it deliberately — it offers a significantly better strength-to-weight ratio than the conventional alloys found in OEM chain tensioners, meaning this part resists deformation under the stress of hard acceleration and repeated adjustments. Every tensioner is milled directly from a solid billet on a CNC machining centre, so tolerances are held tightly across the entire component rather than relying on the surface finish of a casting.
Precision Adjustment on Road and Track
The externally accessible adjustment screw is the detail that makes this tensioner genuinely practical. Whether you are making a quick tension check between track sessions or fine-tuning on the roadside, there is no need to disturb surrounding components. Pair that with the laser-engraved measurement scale and achieving identical tension on both sides of the swingarm becomes a straightforward, repeatable process — eliminating the guesswork that leads to premature tyre and chain wear.
