This combination of tires represent new compounds that likely were not available when the Metz decision was being made back in 2004. But, there is little incentives for Metz to improve the 880. It has to be one of the more profitable tires in their line. And Dealers love to see you for a tire change every 4-5,000 miles. I have gone thru 5 back and 3 fronts so far.
But, the problem I had with the Metz set up was that the back lost it's grip after about 3000 miles. Up to that point it would hold the line in corners, but after that I would find myself having to do slight corrections because of back end slide. This may not sound like a big thing, it does add up after several hundred curves on a normal ride. The tread would wear down really fast on the last 2,000 miles. I have used Metz on several other bikes and was very happy with the performance and value. But not the 880.
I have heard that mixing tire brands is bad. But I think that most tire experts are referring to the mix of Radial and Bias. I also have yet to hear of an accident that was cause by mixing brands. I know very few people keep the OEM tires that come with their car or truck.
Anyway, like most of the riders here, I came from the sports bike and I know what good steering is like. The Commander 2 was the final ingredient. I will also up my estimate and say that is does make the bike feel 150 lbs lighter.
I just got tired of paying top dollar for a really poor product.
Thanks again TriumPhil for thinking out side of the box! This site is great, I would have not tried this setup without the positive feed back from other captains. IMHO, Just try it out, you will never miss the Metz, but if you do, they will still be there for you. $$$$$
