“The weather was great for both days despite what the forecast predicted, which meant we could try different tyres,” added Cummins.
“The Pirellis are pretty impressive anyway, but the ones we ran at the test were even more impressive, which fills me with confidence going forward.”
British Superbike rider Alastair Seeley also participated in the test as he prepares for the North West 200, the only road race the reigning British Supersport champion competes in.
Seeley, who concentrated his efforts on the Superstock and Supersport machines, said: “I was really happy to get back onto my GSX-R600 Supersport bike. It was so nice to ride again and I really felt like I was on rails at Kirkistown this week on the wee bike.
“I also tested the GSX-R1000 'stocker and we tried three different Pirelli tyre combinations. Again the bike felt really good and in certain areas it actually felt better for me than the Superbike.
“So that has helped on a number of fronts and we can take away some very valuable information. We were very lucky to get warm and sunny conditions at Kirkistown and I enjoyed working with Conor. He's a top lad.”
