It was actually the lowest number since 2014. There were 39 official safety recalls in 2016 which was the biggest number in five years: 30 in 2015, 28 in 2014, 20 in 2013, 24 in 2012 and only 16 in 2011.
However, after 75% of 2018, there are already 27 recalls, so it appears the trend is rocketing back up again.
So far, Ducati leads the recall notices this year with four, followed by Honda, Polaris and Triumph on three. BMW, Kawasaki, KTM, Moto Guzzi, Suzuki and Yamaha have had two recalls each, while Harley and MV Agusta have had one each.
