I realize that Aussiebandit, but at least I have a starting point.
I checked with Metzeler tech support, here is my question to them and their answer.
My question:
Which of your two tires are better for wet road conditions. The Roadtec
Z6 or the Sporttec M1? I will be putting them on a 2000 Suzuki Bandit
1200S. I am a USCF Official and use the motorcycle for officiating at
bicycle races. Sometimes in the mountains on wet roads so I need the
best possible traction on wet twisty roads.
Their reply:
The Roadtec Z6 tires are designed to offer more wet grip than the M-1
tires because of compound and tread pattern. The M-1 is a great sport
tire but it leans more towards sport riding, while the Roadtec is a all
season long distance tire.
