I've heard similar things said about the new Royal Enfield motorcycles here in India.
The redesigned J-series engines on their new motorcycles are smoother and I've heard some people wax nostalgic about the old thumpers and say that the new ones "lack character". I've even heard people speak fondly of the the UCE engines (introduced in the early 2000s) which were hated for a similar "lack of character" when they replaced the older engines (which were originally designed back in the 50s I think).
