I had to but a new lock for my ct90 as mine was bent up pretty good. The only lock availble now is a 110 lock its a lil difrent than original locks on the ct90s. But its a honda part sold by the Dr. The bolt pattern is the same on all the locks either ct 90 or 110. The new 110 locks availble from the DR are slightly diffrent the do not have the little phillips screw on the front in whitch a dust cover mounts to. Thanks Gary
