I too enjoy motorcycling. If I wanted to buy retro, it would be HD Heritage or Deluxe; certain Indian models; certain Triumph models.
I’m pretty much in line with that although I have been impressed with the Royal Enfield 650s and I think the super meteor is going to be a very interesting release. If Royal Enfield decides to start making a 750 or 850 twin that will be even more interesting.
I’m not a big Harley guy, I have an Indian Scout. But my first bike was a BSA so I do have soft spot for the British twins and came close to getting a Triumph before I bought my Scout. The other retro bike I would throw in there that I find appealing is the Kawasaki w800, for obvious reasons.
