ADAM Jenkinson spent time on track aboard his team’s new Yamaha R1 machine during a test in Spain last week.

And the Knutsford rider declared himself happy with the Northern Escalator Installations-prepared bike ahead of his latest attempt to win the Pirelli National Superstock 1000 Championship title this season.

“It was a mega first test and we made good progress each day,” said the 30-year-old.

The series hosts an official pre-season run at Donington Park before the first race at the same circuit at Easter.
