I can't agree with you in this criteria because right now most of the Indian motorcycles is delivering more power figure than Yamaha bikes. For example Yamaha Fazer can produce 12.9 bhp where as Bajaj Pulsar Twin Disc can produce 13.8 bhp. Usually Indian bikes are becoming more powerful in this days. Yes still Indian bikes have lacking on braking and balance but engine is well refined and powerful.

And if you still only use it for commuting, may simply be a waste ...
