I own Duet 2 months back and I am having problem in Pertol Tank Cap,
bike fall once and both mirrors comes out even its broke into 2 pecies.
very cheap quality iron rod on mirrors
also horn switch came out twice and I changed from local mechanic .
bike cant go more than 50km if I increase speed engine sound loud than normal.
engine noise while riding more than 50 is very annoying.
sorry hero you disappoint a lot.
I had honda activa in past but I never that kind of problem with it.
