For those who find the Kryptonite NY Fahgettaboudit U lock too short or narrow for their locking situation Kryptonite also makes the M18WL U lock. It is listed in the Powersports area on their web site.

I just got one from Niagara Cycle Works via Amazon. A real brute of a lock, at least in appearance. 3.9" wide by 10.3" long inside the shackle, which is 18mm in diameter. No carrier for frame attachment is included and it weighs just a hair under 6 pounds

BTW the NY Fahgettaboudit weighs in at 4.25 pounds with the same size shackle and the OnGuard Bulldog Mini weighs just under 2 pounds on the same trigger scale.
