The result is a compliant, quiet and durable solution that genuinely suits daily use in the UK.

Built to last

KW’s stainless construction shrugs off salt and grime, helping the adjusters stay free so you can keep your settings dialled. Quality materials and precise valving deliver consistent performance mile after mile.
