US aftermarket exhaust manufacturer Vance & Hines has been fined $500,000 (£320,000) by the California Air Resource Board (CARB) emissions regulatory body for selling about 2000 unapproved exhausts to bike dealers in the state.
This is the largest Californian punishment inflicted on an aftermarket supplier since CARB inflicted a $1 million fine on Dynojet six years ago, in relation to similarly unapproved Power Commander III tuning software for motorcycle electronic fuel injection systems.
Vance & Hines products are distributed in the UK by Manchester-based MAG Europe.
