OEM brake line part # 59480-41F10 new is around $85 plush shipping and tax. I couldn’t find anything cheaper new. https://www.suzukipartshouse.com/oemparts/p/suzuki/59480-41f10/hose-front-brakeWhat's the difference in the price between rubber and braided? How long do you plan on keeping the bike?
Add bolts and washers for another $20+, and total comes out to $115 or so plus shipping and tax.
It is cheaper to buy a new aftermarket braided steel line with new bolts and washers already included. Considering I found a Galfer line for $50 shipped, it is 40% cost of OEM, with potentially better performance.
Time will show, but probably for a few more years at least. I don’t need more power right now, and bike does everything I need it to do.
