^I partially agree with what youre saying. But the problem with that is the manufacturer already puts a certain amount of miles before it even gets delivered to you. Also add to that the amount of miles thats added when its delivered and you almost 100% have missed the period when you can do a hard break in. So I always do a soft break in.
They do but people who do hard break ins well to most of the public at least dont know what their doing, it is sightly more technical, but i believe in hard break-ins, but your braves 3rd day and took her racing !
Everyone has their own opinion on how to break it in. But the most important thing is that you don't actually break it when you do the break in. So whether you decide to do a hard of soft break-in just don't push it past what its supposed to handle.
