Strong and reliable

Great chain. Strong and reliable. Just make sure you have the tool to fit this as it needs a quad stake riveting tool costing £80.

Great quality, watch out for fitting

The chain looks to be very nice quality and I don't doubt will suit the bike. However, I do think that it would be helpful if the description included that the master link is a quad stake type and therefore needs a special tool to fit. We found this out at 7pm on a Sunday night, resulting in an immobilised bike because we didn't have the tool required to fit this kind of link. We then had to buy one, which cost almost as much as the chain again ...... Please make buyers aware so that they can make an informed choice!

Chain has been on a few weeks now, very smooth and responsive. Was diving between this and the Tsubaki Alpha. Fancied a change after having D.l.D VXGB's. Definitely an upgrade. Other reviews are spot on.

A flawless product, that suits the delivery of power from the motorcycle and copes with the stresses of fast gear changes excellently. It has improved the smoothness of the clutch also.

Goldie looking chain

Great looking chain with patented seals. Haven't put enough miles on it to give you the best advice. But the name and reputation speak for it self.

Renthal R4 SRS 525 Pitch Drive Chain

  • SRS ring technology
  • High alloy steel plates and pins
  • Quad riveting and thicker outer plates
  • Chains pre-stretched from the factory

Renthal's R4 SRS Road chain is a specially developed sealed ring chain utilizing Renthal's Self Regulating Seal (SRS) technology to increase the service life of the chain in road applications. The special SRS ring is pre-loaded during assembly creating a spring effect. As the chain wears, conventional o-rings and x-rings lose their seal, however the SRS ring has the ability to unload itself during use keeping a tighter seal against the side plates. This offers increased longevity as the specially formulated grease remains trapped around the critical pin and bushing area longer while also keeping dirt, water and other contaminants out.



Renthal is a global leader in the manufacturing, design and sales of motorcycle, ATV and cycle parts and accessories. It's natural that a world leading manufacturer also leads the world at the very top level of sport. Renthal has attained 170 World Championships and 176 US titles in motorcycling. Attention to every small detail is what it takes to be the best. Everyone dreams of success, but achieving it takes relentless commitment and effort. It's this obsession for detail, quality and engineering that makes Renthal products the finest on the market today.
