I m using Jupiter from last two years.It is a good bike as far as daily needs are concerned. Being a shopkeeper the spacious Jupiter found to be very useful for me.
But I think bit changes are required in it, such as better suspension. As far as comfort is concerned it's OK type, Needs improvement. Also it has a good pickup compared to same other mopeds such as Honda dio.
According to me changes needed in the upcoming model of Jupiter should have 125cc engine and better suspension thats all rest Jupiter is my favorite moped.
