How about the Abus Granit X-Plus 54 U lock?
Will that fit under the seat?

U have to try a few U's out to see what U suits U and what bike U ride.
I could get a big U next to my odyssey battery on my basic cos I have a good space now.
U on the other hand would need a tiny U if its a modern WC thingy.
Or one U could bend ?
A U bend type perhaps ?![]()

So what your saying is a WC needs a small U bend?![]()
I had an idea unsalted butter doesn't work with elephants.
I recently bought the Abus to go under the seat on my TC. Am I missing something though, as there's no way the square lock part will fit, so still left with needing to take top box or tank bag to transport the lock?
Nutty, what year was you're last bike? as my MY16 has the control unit for the dynamic brake thing blocking access under the the rear rack, via the passenger seat.
