Probably Yamaha Maxim XJ550 Motorcycle YAMXJ550HMFH01 Handlebar 278-26111-02-00 or 278-26111-02-00 or 2L0-26111-00-00. (Probably Yamaha XJ550 handlebar part 1.)

Probably the Yamaha Maxim XJ550 Motorcycle Handlebar.  Metal 7/8" in diameter handlebar should work for the Yamaha Maxim XJ550 motorcycle.  It fits into the 2 grooves on the top of the Yamaha XJ550 top of the triple tree part and the 4 small ridged circles on the handlebar perfectly match the 4 ridged semicircles on the top of the Yamaha XJ550 top of the triple tree part.  However, I'm not 100% sure this is the original Yamaha Maxim XJ550 handlebar.  7/8" or 22mm in diameter.  28 5/8" or 727mm long.  Approx. 6" or 152mm tall.  Space between the the 2 sets of 2 ridges grooves on the handlebar: 3 3/8" or 86mm.  Total length of all 4 ridged grooves on the handlebar: 4 9/16" or 116mm.  Sold "as is".
