Both bikes certainly look the part. The obvious lines of 60's era bikes are sleek and maintain that retro look far better than some other brands that have attempted to re-engage retro styling but seem to have become to engaged in modernising the look.
From a brief sit on the bikes (we haven't road tested them yet) they feel light and nimble. The balance is good and the weight feel low down suggesting an easy ride - as you'd expect from such bikes.
Watch out for them next year to see how much of a market share Royal Enfield carve out with the Twins.
