  1. Great to see the bike finally on the road. Congrats to Sandeep Dutta. I however had been riding a Twin Plug Enfield for the last 8 years. In my blog I have detailed how to make this conversion.

  2. even tvs excel 50cc have twin spark pulg….. so watz so new in it? the top speed of excel is 120 km per hour………even ma friend have one…….. the great hayabusa

  3. its really cool

  4. i dont like ur bloudy bike’
    bull shit i need 3 wheeler bike
    i cant handle 2 wheeler bike
    i need only 50cc
    my one tire is gone

  5. Its a step in the right direction but could see that the bike is not fully complete. the gearbox area looks half done especially after seeing the bullet classic launched in the international market. anyway its way ahead of all the present indian enfields.

  6. y no alloy wheels……..& y same rear drum brake…….it really sucks………&too pricey for this…….devil…….
