Hate to spoil the party but just be careful because 'if the TT' has a bigger front brake then the angle of the nipple holes of the rim will be greater on the TT on one side of the rim only--or both side to an extent if both sides are bigger or [or smaller] than MZ250X. Can get away with a certain amount but too much & the nipples are trying to go inline with the angle of hole & the way it's punched out of the rim, while spokes are trying to go off at another angle. Going back 50 years when you couldn't get the right rim we'd just drill the nipple hole bigger to let it lean over more but not good!!. BSA 8 inch front brake was a good example of a big difference [if my memory is ok]. Hope that reads ok, i'll have to stop drinking before evening meal lol. Just reminiscing back to my very enjoyable MX250B days--had one new in "75.
