They should go DOT 4 Zuki. To me it's all the same. I don't know how much improvement you'll feel bc I've never touched the brakes. Just make sure you get a feel for the new stuff. The Busa is a heavy girl and I saw a pic where a dude folded the front forks doing a stoppie, and you don't want to lock the front brake ......
PM Justin with Honda East. I can see a three hour charge. I've read too many horror stories on here with guys bleeding brakes, and you don't want brake fluid on anything. I do my own work but would pass on this job.
Yes, front, rear, and clutch...
