The Danish rider will ride for the highly respected TC Racing/DP Coldplaning team, run by former racer Mick Charnock, and will contest the RST Superbike, RL360 Superstock, PokerStars Senior and Monster Energy Supersport Races on Honda machinery.

The 33-year old came to prominence in the cut and thrust arena of the World Supersport Championship, contesting the series on a full-time basis from 2005 through to 2011. His best results came when he rode for the Hannspree Stiggy Motorsport Honda team from 2006 to 2008, finishing fifth, seventh and ninth overall in the Championship, taking four podiums along the way, including a brace of runner-up spots in 2007 at Donington Park and Silverstone.

An ever-present top ten finisher, he then successfully ran his own team in 2010 and 2011, again on Honda machinery, scoring a best Championship position of seventh overall in 2010. In total, the Copenhagen resident's impressive haul of results in the World Championship saw 20 top five finishes and 41 top ten finishes in seven years of competition.

Harms made his first appearance on the World stage as a teenager in 1999, contesting the 125cc World Championship where he scored points at the season finale in Argentina after finishing 13th. He returned to the series between 2002 and 2004, scoring 13 points in total and recording a best position of 10th at the 2003 Australian Grand Prix.

As well as making his TT debut in 2015, Harms will return to the MCE Insurance British Superbike Championship, riding for the MotoDex Performance First Racing squad aboard a BMW S1000RR. His best result in the series came in 2013 when he placed seventh at Snetterton before injury curtailed his campaign.

Speaking about his planned debut, Robbin commented:

"I didn't think I would have the chance to race in the world famous Isle of Man TT but thanks to the efforts of the organisers and Mick Charnock and the TC Racing/DP Coldplanning team that dream has become a reality. I made my first visit to the Island to see the circuit for myself in December and I am under no illusions as to how much work there is ahead of me. However I am not fazed by this and I intend to spend as much time as I can on the Island learning the course so I am fully prepared when the races begin."
