Gotcha Jerry. But wouldn't you think it would be a great cost savings to HD if they made a good quality part and it lasted??? Look at all those free replacement rotors and the labor they wouldn't have to give away. The poor quality just doesn't make sense. Stuart.
As I have said and some one else in the Thread, Harley figures for the few high milage riders its worth the trade off. So on the rotors if say only 15% of the bikes see more than 3500 miles a year, those are the only rotors they will be replacing under warranty. But they saved 25% in cost on the new cheaper rotors, its a net savings of 10%.
Think of the twin cam 110 motor. Lifter failure is very very common some where over 20K miles. How many bike see 20K miles in less then 2 years? Not many, so it was not cost effective to fix the issue. A friends 14 CVO which was built after the new lifter that claimed to solve the issue, had his lifter go out while we were in WA, with 21K on the bike at a year old. Another friend had lifer go out an motor replaced at 36K on has 15 CVO. I had lifters go out at 44K on my 15 and engine replaced under warranty.
Yet I see 15 CVO on the floor for sale with 18K miles or so. So, not fixing was cheaper for HD.
Sad to say their business model is make it as cheap as possible, but last long enough that the issues do not show up until after warranty for 85% of the riders.
