As you got a bigger country you have a lot more different conditions.
Concerning the grip of the HPX , the tire needs more time to warm up , but then
its ok.
When you ride in warmer regions its well from start , and you have a good mileage .(it will make 6.000 km~ 4.000m)
If your running sporty stile (have seen the "Dragon") the normal PP is FOR ME the ultimate choice but not as 2CT.
Also in wet conditions TOP.
Concerning the Metzeler , its a verry good tire , but at its end it "slides" more than the michelins.
Another thing is , that the "end" of the tire is not so good visible because of leaking profile in the middle of the tire.
So ,after a ride suddenly you see the steelbelts comming out , and the tire even looked good before start.
A lot of drivers here run the Z6 and are lucky with it.
But my personel opinion is , that everybody should ride a tire that gives him a good and secure feeling. If there is any doubt , change it , and try to find one which gives you better
feeling.
The more you trust your tires , the better you ride.
To reach the limit of these modern tires i think you have to run over your owen or the bikes limit. (a well warmed up tire as base)
On public race-trainings , some can scratch their fairing without loosing grip of tires , and there are some on HPX , some on PP, some on Metzeler , some on pirelli
I made such a training one time (only scratching the footrest-pins) and saw what these tires are able to hold.
Thanks for beeing so friendly to me (and my writing
