Six of the nine teams participating in the SES TT Zero Clean Emissions race used the opportunity to get some early practice in ahead of Wednesday's race on the mountain course.

Mark Miller won last year's race for the MotoCzysz team but with the American choosing not to run, it was left to his teammate Michael Rutter to go fastest in a time of 24:23.99, an average speed of 92.779mph.

The 39-year-old was still just over a minute slower than Miller's race winning time from last year and the defending champion will go into this week's race as the favourite for victory.

Experienced electric campaigner George Spence, riding for Kingston University, was the first rider to take to the course and is one of the leading contenders for the £5,000 University Prize. He clocked 81.823mph on his run.

Ramsey based Allan Brew also went out, representing TT Zero newcomers MIT. The prestigious American University are expected to challenge Kingston for the prize and all eyes were on them to see how they would fare in their first assault on the TT.

Tokyo-based outfit Team Prozza are also entering an electric bike at the TT for the first time with Yoshinari Matsushita on board. The newcomer ran closely behind the experienced Rutter as he got to grips with the 37.73mile circuit. His best lap saw him average 66.113mph.
