Just saw this thread. I ran the V3’s and literally only got 972 miles out of the rear riding hard in the Deal’s Gap area. Roads were Tail of the Dragon, 28, 129, 197, 60, 64, Warwoman Rd., Blood Mountain and a few others. My bike is an 18’ R1 with Ohlins front and rear with a Woolich flash and Akra 3/4 system.
The 60 profile provided a steeper turn in although not much more then a V2 as I thought it might. The main difference being the rear height was slightly taller giving the rear more of a wedge effect. While the rear is dual compound, the harder section is literally only 1 inch wide down the center and can be seen after a few miles of riding. The SC rubber on the sides actually appeared to heat up quicker than a V2. You can feel the tire is slightly softer when brand new.
The tire obviously gave me more lean angle at full retard pace and didn't give me any random slippage other then my right hand giving the bike the beans at full tilt. The powerslides were easily predictable and manageable like the V2.
The bad, the tire wore out about 300 miles before my V2's at the same pace and same routes in the mountains. For the latest and greatest offering from Pirelli I would've expected a little more advancement in durability regardless of the advertisement compared to it's predecessor. Save your cash and continue with the V2's or K3's unless you want that 60 profile costing quite a few pesos more. Even if you’re running solely track days I’d stay on the V2 or SC slick because of the better wear.
