nope its not like that , the guy ur talkin abt switches bikes regulalry like some1 changes clothes , he has bought now another junnon in black colour again
new bike has some adjustments problems in brake, can be adjusted by some good mechaninc in hardly 5 min, never give up ur decision on such small things like , brake lether and nut, bolt vibrations , wheel alignemnt etc
every new bike u will buy will have such minute issues but they can be corrected by tunning and adjustment
if u like junnon go for it , its a good bike , dont think wat people say, bcz everybody will tell u a different story,
major issues are that its engine is gud or not , thats it , coz its the heart of any bike , rest almost all the companies make good frames and body
rest i ve already told u abt the ratings , decision is urs
