Electra Glide in Blue
Can we blow this one up a bit bigger? I think it is an early '50s Triumph. Thanks for that. Yes Triumph. As it has a rigid frame it should be late 1940s and will be 500cc. Call it a 1949 Triumph 5T and see if we get a reaction from someone who can be more precise!
I can't read much French but I think that says that recognition is difficult - agreed. We can't see enough of each bike to positively identify them. I think the one on the left might be an early Yamaha. The BSA is probably an A10 - maybe a Super Rocket.
This bike is 1970 or 1971. Not earlier or later.
