Buying an R15 and extending the wheelbase will not give you a Ninja. Plus, if you really think the deltabox is "ill-engineered" ompared to a regular "diamond tube" chassis, we respect your belief, but don't try to make us believe the same here. We believe the R15 is only limited by its engine. If argument about other bikes is all you want, look out for another thread, this thread is limited to only YZF R15 and its discussions.
