Motorcycle wall bracket

A brick wall is strong in compression, but with the bike suspended outside its plane, you are adding a sheer force and turning moment at the fixings (which will likely be your limiting factor).
If you can get the other side of the wall, then bolt through to a plate you would have a far better chance.
In all honesty, I would get an engineer to check the wall construction and advise.
Yes, this seems a perilous venture. Even with a plate on the other side, it's a lot of levering force. 4x 10mm resin-injected studs will easily take 200kg, but I suspect an ordinary internal half-brick wall wouldn't be as happy about it. Maybe a thicker exterior wall would cope, but I would want at least a metre of vertical fixing (could be under the plaster) to avoid concentrating force into a few courses. Or you could "make a feature of it" by bolting a steel frame to the full height of the wall - would look smart in stainless, or sprayed to match the bike.If you can get the other side of the wall, then bolt through to a plate you would have a far better chance.

I wonder if it might be a better option to hang the bike from above, with some smart stainless steel bits (boating chandlers). Would depend on the construction of the house, but joists are designed and intended to hold downward force. 100kg on each end is only the same as a fat bloke standing on the upstairs floor. Strong joists near to a wall should be more able to take this load, and could be more easily reinforced. Maybe lift a few floorboards and bolt a piece of angle iron on each side of the loaded joists, to prevent bowing over time. Or notch 6 joists and lay a steel bearer across them to spread the load.
