520 R3-3 Off-Road Chain

Renthal

£105.95

Renthal R3-3 Off-Road Chain boasts a unique Self-Regulating Seal (SRS™) design that are pre-loaded during assembly. The spring effect created during this process delivers constant seal pressure as the chain wears, allowing for extended lubrication intervals while delivering incredible durability unlike traditional O Ring chains which lose sealing pressure as they wear. The result is a strong, long-lasting, high-performance o ring dirt bike chain, ideal for extreme offroad enduro applications. The R3-3 SRS chain utilises the same high performance materials found in the Renthal R1 Works MX Chain

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as RENTHAL LIMITED, number 01224533. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Stated by the company: "In October 2000, the Renthal factory was destroyed by a massive fire. What replaced the original factory was a completely new, state of the art manufacturing and design facility. Renthal's 49,000 sq. ft. factory houses a huge and diverse range of production, quality control and R&D machinery and equipment." Source.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
No majority shareholding traced outside the UK. Companies House.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
