Did a Pirelli-sponsored track day this past February,riding on a 1-2 month old(600 miles, street mileage) set of DSC SP V2(180/55 for the rear,first time using these DSC SP V2 at the track) set at 31/27 cold. Due to work commitments,I didn't track again until June,but installed a new SP V2 180/60 for the rear.
That last time in June,however,I was faster and more stable,having set the pressures to 30.5/26 cold and had the suspension re-tuned(from last year,running street on the DSC SP V2 180/55).91-94 F temps.trackside.
Laptimes were 2-3 seconds faster.
This coming from a novice class td rider(in February) and very sore and stiff,47 year,very,OLD man,lol.
Will be in intermediate next td. And hopefully,enter the Pirelli Rookie Cup starting April,2017,here in the Philippines.
Lots to learn and practice and at times,humbling and frustrating,but,nevertheless,it's a fierce blast
