Former Grand Prix winner Jeremy McWilliams made an instant impact on his Superbike debut at the North West 200 on the Mar-Train Yamaha R1.
McWilliams lapped at 118.060mph to finish 11th fastest in the opening practice session as the 52-year-old fills in for Dan Kneen, who sustained a broken arm following a bicycle accident last Friday.
The Northern Ireland rider, who was riding a Superbike competitively for the first time in seven years, went through the speed gun at 197.5mph on the R1 and is now eager to improve further in Thursday's final qualifying sessions.
McWilliams, 11th in the Supersport class and 14th in the Superstock session, said: “Today was good, I made a few mistakes on the 'six hundred' on what was my quickest lap and had put together a really good lap on the Superstock bike before the red flags came out with one corner to go, so the timesheets could have looked a bit better at the end of the day.
“The bikes are good, though we need to work a little on the power delivery of the Superbike but I'm really enjoying the 'Stock and Supersport bikes. It was a very busy day but I felt good at the end and would have liked a few more laps on the 'Stock bike so riding in all the classes isn't an issue.
“I know where both the bikes and I can improve so I'm looking forward to Thursday to see where we end up.”
McWilliams, who won the second Supertwins race at the North West last year, was sixth in the class as he teams up again with Ryan Farquhar on the SGS KMR Kawasaki.
