The 2018 Isle of Man TT opened practice week with fair weather and fast times. The riders were able to get in sufficient practice laps to refine their lines and reference points over the 37.73-mile course with more than 250 turns. Although unofficial, Dean Harrison posted a new course record of more than 134 mph.
In the opening RST Superbike race Harrison, the Silicone Engineering Kawasaki rider, shattered the outright lap record from a standing start with a lap of 134.432 mph to open up an 18-second lead. However, mechanical issues forced an early retirement for Harrison and Michael Dunlop took his 16th TT on his Tyco BMW S1000RR Superbike.
On Monday morning for the Supersport race Dunlop’s MD Racing Honda shattered his previous course record with a second lap of 129.197 mph. Harrison continued his fast times coming in second with Peter Hickman in third.
In the second race of the day, the big bikes returned for the four-lap Superstock event. As expected the battle was between Dunlop, Harrison, and Hickman. In the end and after 150 miles, the top three riders were only separated by 14 seconds with Hickman on top for his first TT victory. In spite of a slower than normal pit stop and a missed turn at Braddan Bridge, Hickman was able to maintain his composure and push on every section of the course to take the win.
