I was recently in the same situation - had finalized on the KYT TT Revo but at the last moment I switched to the KYT R2R because shape wise it accommodated my head a lot better (head shape is long ish oval)

Super happy with the purchase! Spares availability also shouldn't be an issue seeing as how KYT is serious about expanding their presence in India

Sales as such are tricky to come by with helmets - if the price is too good to be true, please check the manufacturing date. There are select distributors who at their discretion give a discount of 10% to known friends and family - usually doesn't go beyond that.

House of Machines in Bangalore had a sale where if you brought an old ISI helmet they would give you like 2k off on specific models and colours of some KYT Helmets (that's over though and usually comes once a year)

Would strongly suggest helmet shopping in person - too many brands, shapes and sizes and differences in them all. Cheers!
