The indian model costs about 1000$ less than the qouted 7,500$ for the american version.
The price cut has been achieved by fabricating and sourcing most of the parts from within india like the frame or the engine head for example. Even the tyres are MRF while the USA models will have better michellin tyres. But given the type of roads we have here , MRF is prolly a more durable choice compared to the softer compound michellin.
For a price comparision , a kawasaki ninja 300 on road costs 4 lakhs while the street will be touching 5 lakhs in some states. Performance wise as well as build quality , the kawasaki is better though it is considered overpriced by many(a honda cbr 250 costs 1.7 lakh and it has ABS , a KTM 390 single with ABS costs 1.8 so you get the idea). So even though marketed as affordable , the harley street is a pure luxury product when compared to other options here.
