Acumen, the UK’s leading motorcycle electronics manufacturer, have developed a plug-in alarm system that will upgrade 2006 model Yamaha R6 motorcycles to highest category for insurance approval. Like many of the latest high performance motorcycles, the R6 has a factory fitted immobiliser that is approved to the Thatcham Category 2 (CAT2). However, many insurers insist on a full Category 1 (CAT1) system for these machines and will also offer lower premiums to owners who fit them.
