yar .... gto/rx/gp were never banned first of all its a hoax!!!
it ran out of bussiness due to halt of 2stroke bikes development from where they were imported mainly japan becuase they upgraded to higher level rides ( and shifted this category to other countries), secondly under sale (even my grand dad remember they used to distribute gto110 on lucky coupons because no body was interested to buy its also a hoax that the have good sale good sale was of yamaha yb, piaggio scooter and it was ruling), and specially gto companies owners issues that what i heard from my elders and many gto/rx collectors ....
old cg never reached 120 too... even not the pointer until you make its engine to "race" setup even then it would be a miracle or a favorable weather and road not the bike and yes no cg is speed locked in Pakistan its just a hoax i am engineer i know whats going through wires ...
new 78cc chonda can easily reach uptil 90kmh where as hondac70 can also reach near 90 but as engine tears down by the time so does the speed..
125 has 55 cc more which give it enormous acceleration edge and around 25kmh speed head above 70cc counter part which is understandable being a commuting 125.
may be i am wrong but thats what i could found in news, from elders, from mechnics...
