Opinions on front brakes

This may also work (not 100 per cent sure about the OD) 64 mm ID and 80 mm PCD is the same for Ducati and the XS and many other Yamaha models.

With that set-up and a stock MC is the split at the switch unit? If so it’s just a matter of removing one line and using a shorter banjo bolt. Put the spares on the shelf.

The split is on the lower triple tree, not sure if that’s the switch unit you’re speaking of. I won’t have any spares as there are no lines on the forks I bought. The rotors are the only remaining part of the front brakes so I’ll just be removing one of them and then buying an MC with a brake light switch in it and a single braided stainless line from MC to caliper.

Forgot it was a ‘73 set up. I like using these.

Dual discs do look nice, but also means a ridicoluos amount of unsprung weight, especially is you plan to use stock discs and calipers.

I didn’t realize how heavy the stock rotors are until I removed the one yesterday. Totally understand now.

On my "Euro" 77D, swapping out the original 267 mm dual discs and caliper for a single 320 mm ISR disc, a Brembo 4 piston caliper, and a home made caliper adapter, plus an alloy front fender, removed around 4.5 kg/ 10 lbs of unsprung weight. Which improved the front suspension a lot.
