I bought hero duet last year in January 2016 and today I crossed ten thousand kilometers:).my experience is good with no service only oil change once for two thousand kilometers:).this is Indian scooter and we should encourage it:).though pulling is good in activated when compared to duet, duet has metallic body and does its job decently:).u take any vehicle of any company, maintain it well, service it well, wash it nicely, ride gently and slowly definitely the durability is more:).I love my duet, my Honda activa, my santro car for wat it is without over judging it:).good day:)
