Thanks Bulletron_Max!!

Before I start passing the information, let me congratulate you on your choice, and of course, purchase!
Rs.1600 for Diamond crash guard!!!!!!

..... it's a bloody loot!!

I bought the crash guard for my Electra in Rs.650/- and
Diamond crash guard can be bought for Rs.750/ or less (not more than that) in open market. (My apologies, I had asked the price for
Diamond crash guard but unable to recall it anymore, I think it was Rs.700/- or Rs.750/-)
Ok, let me suggest you one thing, please do not buy anything from the dealer, not even the buzzer!
There are many places in J. C. Road (I'm pretty sure, being a Banglorean, you would know J. C. Road) from where you can buy Bullet spares. But there are two very popular dealers who give Bullet spares at very genuine rate, one of them being
Sandhya Auto Spares.
Let me provide you the direction to Sandhya Auto Spares:
1. Once you get into J.C. Road, look for State Bank of India bank (there is only one SBI in J.C. Road). SBI Bank come after the first signal and on the right hand side, while moving towards Town Hall.
2. Adjacent to SBI, there is a thin concrete road. Take that road and 50 mts ahead you'll find two spare shops. The one on the 1st floor is
Sandhya Auto Spares and below is another one who's also a dealer in Bullet spare parts. You can buy from either of them since I tried both of them and seemed to be genuine spare dealers.
Remember!!... to negotiate the price with them and to the max

If he says 650 then go for 500

... I am pretty sure you'll find a good deal.
Cheers!
