Hey, I am a new owner of an 08 ZX10R. I have been really curious about what the best way to break in the new motor is, and have found excellent advise here. However everyone seems to talk about staying away from constant rpm's. I was wondering how long is this advice applicable? How many miles should the bike have before I can confidently ride on the freeway keeping the rpm's around the same value for the whole ride on the freeway? Or do you want to try and always vary your rpm's for the whole life of your bike? Is avoiding constant rpm's just applicable to "break-in" period? And if so, then for how long until you can use constant rpm's. Or is it something you want to do for the life of your bike? Sorry for the repetition, and the same old post.
