Brake line routing question
So the stock brake lines have a splitter on the way down to the calipers..
GSXR's have the brake lines go to one caliper first, then run a line over the fender to the other caliper.
Aftermarket brake lines for the most part run two separate lines all the way back to the MC.
Does any of this make any difference? Obviously going to SS lines does, but does the routing make a difference?
The reason I ask is that locally I can find on sale SS brake lines for other bikes for quite a bit cheaper than a kit for ours, and the longer line is plenty long enough to run to the shorter side of our bikes, and the short one would reach just fine to the other side over the fender. (like a GSXR)
And since I am doing a GSXR fork - brake swap, I'd be keeping it like stock, only with SS lines.
Is there any real reason not to do this? (I actually plan to unless there is a compelling reason not to)

I picked up a set of gxsr 6 pots with s/s lines and m/c and I too looked at running the lines from each caliper to the m/c using a longer bolt. The lines are sufficiently long enough to reach the m/c with plenty of play. As long as the brake system is bleed properly, it should not really matter the routing of the lines.

Stock MC with VTR designed SS Lines
GSXR Radial MC with the VTR designed lines rigged to fit the Radial MC instead of buying new lines.

When I did my front end rebuild I made the mistake of making too many changes at once. I bought 6 pots, Greg did my forks and we dropped 10mm in the triples. I also installed Heli's. The after market ss lines just barely made it and routing through the stock hooks was out of the question. I bought the lines for a stock Superhawk thinking that there would be a little play from the mfr - not. It's a good thing these lines weren't 2-3mm's shorter or they wouldn't have made it. I think buying by length is the best route after doing the mods. I didn't know where to buy lines by specified lengths.

I just did my front end... Greg rebuilt my forks,Heli-bars and S/S lines.I ordered HEL brake lines and had them 2" longer than stock to account for the higher bars.Everything fitted fine and have had no problems......

Nuhawk HEL used to be out of Florida but has since closed down the business. The only place to order HEL lines are out of the U.K.
I bought the front, rear and clutch lines and had to send the fronts back because they were too short after adding the RT fork springs. I had them add an additional 3" to the front lines. I have been very happy with the quality and performance of the HEL lines.
