Now the other thing that is completely underrated is the stock Yamaha single piston caliper. The real reason, why it is often given such bad credit is that the stock brakepumps are too large, they usually are in a bad state of maintainenance and people try to run them with 30 year old rubber brake hose, which inflates like a balloon on a children's birthday party.

Slightly less critical, if you do it wrong, but equally important: Remove the slider bushing on the bottom of the caliper, clean it until it is spotless, lube it up with brake grease and reinstall it. This will stop your pads from wearing unevenly.
Now luckily, these calipers have been fitted to a lot of different models over the years and as such overhaul kits are cheap and plentiful and you can even get pre-made stainless steel brake pistons for them.
One of the other benefits of beefing up the front end was that the XS could now run the bigger 298mm brake disks. Incidentially this is also the diameter of the full floating brake disks on various later Yamaha sport replicas (e.g. FZRs) and the bolt-hole-circle is still the same. Unfortunately the off-set is a bit different, so one has to knock up a spacer to centralize the brake disk in the caliper.
