as per my view, only classical type people go for HH. They dun care too much on mileage, power,looks or anythin[ i mean low end HH]. So their usage too wud be like that only...might not even know what rev..ing is. So shud last long and locks much late.
But those who pick according to reasons like mileage, power or looks might probably go for anythin other than HH [ZMA is an exception]. And ride according to their needs...might over rev as well. So might lockup early.
im saying this coz i havnt seen any one even trying to rev on a splendor .. to glamour. But have seen many trying to kill the engine of platina, discover, stunner, and even gladiators.
So not much point in "anythin other than HH locks up early".
My bro owns a glamour and its a pure piece of shit, even if he never even over rev or do anythin harmful for it. And so is some of my frend's glamour... So as per me, HH sucks[again except ZMA

].
ALso proper servicing is a key point. Heard bajaj service centres doesnt do enuf justice on thatfrom any, but not in my area atleast. Here bajaj servicing is one of the best, yamaha and HH being the worst.
