I'm looking at overhauling my 620's front end and gathering the last of the bits needed for the superbike conversion.  I have a set of goldline master cylinders from an S4R, and would like to change out the brake lines for a better fitting superbike set.  Are the 848/1098 brake lines compatible with the goldline masters?  Is a different banjo needed at the master?  I understand I'll have to get a double banjo for the right caliper.  Thanks.

i'm running the goldlines with 848 forks and I think a 916 front line. it's too long. so I may be looking for the 848 line as well. the lines are pretty much interchangeable. the 848 runs one line from the master and a crossover line i think

848/1098 have radial master cylinder and radial calipers.
Radial master, the banjo bolt goes up from the bottom.
Radial caliper, the banjo bolt is at a slightly different orientation than on axial calipers.

May not work well with your goldline master...... and.....

What calipers are you going to use?

My '04 620 has the original dual 320mm gold line calipers.

When you say 'may not work well', do you mean the length will not be correct at the calipers?  What would be the problem at the master?

The OEM brake line your bike came with is the best fit for regular bars.

If you're going clip-ons, a 748/916/996 line will likely work.

Cool, I'll keep my eyes out for a 916 setup.  It looks like Gotham Cycles offers the lines for 25 bucks. 

I saw Spiegler and Galfer offer brake line kits for the 916/996 series bikes.  Spieglers are a little pricier, but have more color options. 

The two companies also offer an alternative to the single line with a dual-line setup coming off of the master.  Would an extended banjo bolt cause any clearance issues?  This setup is $60 cheaper than the standard single to split routing.  What am I losing/gaining by going with two lines?

Regular bars?

Suburban Machinery bars?

Clip-ons?

If so, above triple, below triple?

Speedymoto no-rise clip-ons (not the tall-boys)

From what I've experienced, you "may" run into double master banjo interference issues with the following:

1) Gauges,
2) Fairing mount tabs, and/or
3) Headlight brackets.

Depending on if you have lowered your gauges, and how you bolt everything up,...YMMV

Some will say they can notice a difference in feel depending on the set up, and/or bla bla bla

It's an aesthetic personal preference in my opinion.
