george; i never owned or worked on an 1125 front brake system but they mirror the XB brake systems which i have serviced dozens of. a super touchy lever combined with pads that dramatically clamp the front rotor and won't release can only be 1 or more of the following 3 things:
1-master cylinder needing flushed...bleed hole cleaned....and/or rebuilt
2-caliper pistons stuck in their respective bores from either warping or corrosion
3-faulty collapsed brake hose/hoses.
as with any brake system if you're not somewhat experienced with them or feel a certain amount of trepidation diving into one then have a pro go over it for you. a quick trouble-shooting test is to get the front wheel up in the air...spin the wheel...apply full firm front lever pressure and release. now wiggle the wheel lightly at 12 and 6 o'clock position and try to spin wheel. bound up? it's one or more of the 3 above i listed. corroded interior portions of a master cylinder creates not only locking wheel symptom but also a "wooden" lever feel.
