Might be hard to pop a wheelie with that bad-boy.

Re: GT750 4ls brake on a T125?
The GT750 4ls is 20+ lbs for the drum and backing plate assembly with shoes. And serious overkill for the T125
The T250, T350, and T500 all used the same drum. On the 250 and 350 it was sufficient. On the 500 in today's traffic it can make for an exciting ride.
If you really want a bigger front brake, what you could do that would be cheap and effective is pick up a CB350 twin leading shoe. All the racers are discarding them in favor of the 750 4ls or the drums from the CB450 or CB72/77 but it would be well suited for your 125.
