What's the triple tree width on the New Bonnies and Thruxtons? Wider than a Harley Davidson narrow glide, I hope. Can't run Hawg Halters' four piston dual disc front brakes on a narrow glide with wire spoke wheels.

Yep, think I'm going to do Harley Davidson 41mm forks with dual disc front brake lower leg sliders, all on stock Triumph trees. Anybody done this before?

Every H D I've ever ridden had lousy wooden brakes no matter how many discs were on the front. Of you were going to the trouble and expense of putting a/market brakes on a H D front end on a 'Bonnie, it would seem to make more sense to just buy an a/market system for the 'Bonnie. With enough pistons gripping the single disc I imagine the 'Bonnie would stop pretty well.
Having said that, I can understand why you want to do it so if it works let us know.

yeah, a rocket 3 master cylinder will fit the bonnie controls (I have one on mine), a 6 pot caliper, and a floating rotor would make a stoppie machine. All parts readily available to bolt on too. Of course, that's not what I did :D
