I agree completely. Well...except for the 15,000 rpm redline of the CBR250RR. I believe the redline was closer to 18,500 or 19,000 rpm.Your very first post detailed all the "deficiencies" of the new 250R vs. the old 250RR when in fact they are designed for different market segments. We all understand that here. You are assuming that the OP is trolling when it's very possible and more likely they just want information. We have a lot of new riders on this forum that don't have a lot of practical experience and just want good information about what to do and what not to do. For you to come along and tell us we don't know anything about motors is, well, trolling. Especially when your experience is based on an ancient bike that needs to rev to 15,000 to make 45hp through a set of outdated wheezy carburetors.
