+100cc

[Bob_Defly]

Why do bike manufacturers seem to add 50cc-100cc every couple of years to each model in their line up. Only to have to reintroduce a new smaller capacity bike like there wasn't one before? Why can't they just make the current model better / lighter / faster?

Is it just a marketing ploy, so if you started on a KTM 390, you'll buy a 690 - 790 - 890 - 990 - 1290 - 1390?

Surely they could still release new and improved models without increasing the capacity, and still keep the upgrade path.
