Back in 2013 I bought a new Royal Enfield B5 Bullet. I rode it stock for a couple of years, then put the shorter non catcon pipe on it, and replaced the EFI with an Amal Concentric Mk1 with a kit from Hitchcocks in the UK. It runs and sounds a lot better than it did stock. I recently went passed 10,000 miles on it. They are definitely not high quality bikes, the RE forum is just full of nightmares, from broken engines to broken frames and everything in between. I never ride mine above an indicated 60 mph, and usually at 55 mph, which seems to be it's sweet spot. It doesn't seem overstressed, and you can hear that wonderful thumping sound and feel the relaxing low frequency vibration. It has had it's share of mostly minor problems, on the day I brought it home the rear tire chewed through the wiring harness to the tail, brake, and rear turn signal lights. The header nuts refused to stay tight. The lights all burned out and the speedometer cable broke. But the biggest problem so far is the rear brake failed. It locked up solid. Fortunately I was going slow, and didn't crash. It had been making a scraping noise since I got it, but I rarely used it. I took it apart and found all the lining material had been ground off the ends of both shoes, and that the radius of both shoes was considerably larger than the inside of the drum. Right now I am riding it (out in the country) with no rear brake. I have no idea where to get shoes with the proper radius. I can order some new ones, but they could be the same as the old ones. Nobody else on the RE forum seems to have found this problem, but I can't be the only one with it. Ride these things slow, and do LOTS of maintenance, and they should last for quite some time. Definitely do not treat them like a modern bike. My guess is that the 1950s made British made Enfields were better quality than the new ones. Many dealers went out of business. My nearest dealer is now three states away. Fortunately Hitchcocks has most of the parts, if you don't mind paying shipping from the UK.
