Well,..Personally Unlike Stuntmania ,Roadies is all about cat fights and group politics and ugly words bashing.I thought of Roadies to be a series where Nationwide Touring on Motorcycles will be Profiled.Infact, way back in 2003,it actually started like that.but ,then for TRP ratings ,they made it another "serial" like program 
Hope Roadies 7 will be better.

Moreover ,the New Hero Honda Karizma ZMR with PGM-FI (fuel injection) will be the Bikes going to be used.
