Not like Honda to make a long stroke engine, but the bore & stroke are near identical the 350 Bullet to get the same "feel" and exhaust "thump", but with balance shafts to tame vibrations. Slightly more powerful and has more torque than the upcoming Meteor, both at lower revs.
Two different spec. levels (the basic version is in the pic - the higher spec. models get two-tone paint & a few more farkles). Prices are £100-£150 more than the old 350 Classic Enfield at around £1900-£2000 in the Indian market.
No suggestion that these are going to be coming here. There should be no emissons reasons, as new Indian bikes have to meet their "BS6" levels, which are tighter than the upcoming Euro 5 levels here. The "BS" levels have largely mirrored the equivalent Euro levels, but they chose to go directly from level 4 (where we are now with Euro 4) to level 6 without bothering with Level 5.
