Interesting motorcycles, not XS650

[siscoken]

Any of you Yamaha Guys help identify this bike that showed up on FB marketplace locally?View attachment 363342

IMHO, the XS1100SF was the best looking Yamaha Special.

I have not contacted the seller.... really not my style of bike... asking $ is 200 cad.... so probably a pretty good deal to the right person... likely no paperwork.
If I am to get another project .... it has to be something I am going to ride or I will loose interest.
That's for the info.

The Triumph TR5MX, also known as the Avenger, was a short-lived (1973-1974) 499cc off-road/trail bike, essentially the last of the BSA B50MX models rebadged under Triumph after BSA's demise, featuring a torque-rich, long-stroke engine, oil-in-frame chassis, and minimalist styling, popular for its classic scrambler look.

Something a bit different. A batch of ten trials frames being made by John Hand Racing. Lovely hand made, bronze welding/brazing construction.

Lovely, why braze rather than weld???? My mindset is why glue than actually "alloy" the two pieces in a joint???

I actually don't know why. Sorry.

A good question, and I don't really know the answer except that such was the way high performance motorcycle makers and racing motorcycle frame makers have (or had) done for years.

Brazing causes less metal distortion than welding. That means less fixturing required on assembly.

I figgered' you'd have an explanation.

Avoids martensite formation in high strength and high carbon steels also.

Turn up the sound if you like a little high rpm music.

Aren’t some high end titanium race pipes still “furnace brazed”?

and overheating 4340 or other HSS kills the UTS at the welds

Jim's got it correct
