The progress in the last five years on electric motorcycles has been astounding. Taking their first laps around the Isle of Man TT Mountain Course, a 87.434 mph pace was the best an electric motorcycle could do at the prestigious road race in 2009 — a pace that was on par with the 50cc record set in 1971. Since that time though, the development of these machines has grown by leaps and bounds.
In just five years after the first laps were taken by electric motorcycles at Snaefell, these machines have grown their average lap speeds by over 20 mph at the TT Zero race, setting a new record of 109.675 mph in 2013, and boasting a rate of improvement of roughly 5 mph each year since 2009.
If hitting 142.2 mph down the Sulby Straight speed trap wasn’t further proof of the speeds these bikes are achieving, maybe some visual evidence will help support the notion.
