No. But I have have been through two sets on the road. One on a ktm1290 gt, one set on a multi. Yes, you could do trackday. But, if you normally get to the edge of your tyres, you might wish you had gone for something more sporty. I got to the edge of the Angel Gts before my KTM was run in, cold weather and crap roads. Would suggest if wanting to push even a little bit to use a different tyre. If just wanting to circulate and have a bit fun, they maybe ok. No heroics.
