Isle of Man TT bosses have suspended the all-electric TT Zero event for the next two years, starting in 2020.

The decision follows a period of significant milestones and success, however, the running of this class and participation of the associated competitors has been increasingly challenging.

Therefore, the moratorium will allow the Department to engage in a broader dialogue with stakeholders, including teams and manufacturers, to develop and expand the class, building on the success to date and working with the industry to establish long term plans for clean emission Motorcycle racing and technology development on the Isle of Man.

"As an island we remain committed to the principles and passion that continues to motivate everyone associated with the TT Zero class and the clean tech industry," said minister Rob Callister.

"Our intention is to have a moratorium on the event to allow the motorcycle industry as a whole to catch up on the leading edge developments that some manufacturers and individual race teams and universities have achieved to date.’

"We remain incredibly proud of everything that has been achieved in clean emission racing at the TT and will work closely with the industry and with manufacturers without the pressure and focus of delivering a race format to build on the success to date."
