My GS 1000 ST is now fitted with Salty Monk's conversion kit.
I used CBR 900 92-93 disks with SV 650 04 ? calipers.
It all came together very nicely and the weight saving is substantial!
The total weight came down by 1340 gr including the brackets in the kit.
I believe the kit looks fantastic with the larger disk better filling the 19" front wheel.

Thanks Dan!

I have PM'd you John. Yes Paypal works.

Great Dan!
I will place an order asap.
Will Paypal be OK? If so please send me the address. Mine will be included on Paypal.
Thanks
John

John you'll have to swap to the CBR disks or someone used a set of Valkyrie ones back in the thread somewhere if you want something a bit more classic looking.

The SV650/DL650/EX650 all used the same caliper. The Kawasaki ones are the newest I think - from about 2009 to 2016. I think SV is 99 to 06 and DL is 2004-2011.

You can use the very newest EX650 ones I think (untested) but they use an 8mm bolt and are nissin not Tokico. I bought a set to try and was going to drill out the threads and re-tap to M10 fine. There is plenty of meat to do that. I still have them in a box somewhere....

My guess is about $125 to get them to you all in.

Hi Dan,
I'm looking into the purchase of one of your front brake upgrade kits for my GS 1000 ST.
A couple of questions:
Do the SV 650 calipers work with the kit and if so what model year?
Does the kit work with the OEM slotted disks of the 1980 GS 1000?
Will you please send me a quote including shipment to France post code 47330?
Thanks
John

I wanted to bump this thread as a couple of people have asked me about it. I do have a limited number of bracket & spacer kits left (all powdercoated black as normal) but I likely won't be getting any more following this batch, not so much demand any more.....

I may have a set or two of rotors somewhere & a Master cylinder or two that would work well with either of the caliper types that work (Ninja/Concourse or EX650 / SV650 / DL650)

Good idea, I've given your email address to a couple of guys who have since gotten hold of you.

Set of 83 forks have arrived, pair of calipers from 01 Concours arrived, rotors for a CBR600F3 arrved, some various miscellany and I can swap out the front end on this '81 gs1100e for twin pots.

Stainless steel lines I just put on already made a noticeable improvement over the (no exaggeration) 41 year old brake lines (yep, had the original lines manufacture date 01/81 still legible).

Be interesting to see what you find out. I've not directly compared a G to an L as far as width from memory.

[Eric]

Thanks- Im going with the G triple to keep the rake reasonable. Ill measure stuff up when I have parts. Pretty sure the leg ctc is narrower, but not sure if the axle mounting faces are the same width. I guess Ill find out!

[salty_monk]

When going from a 650GL to a 650G fork for dual discs, will one need to also change the axle and spacers on a GL wheel to fit the G fork? Thank you.

If you use the original triple tree then in theory the spacer pack and axle should stay the same...

In practice most are interchangeable apart from there is a different in the 35mm fork leg axle as opposed to the 37mm fork leg axle. Most of the triple trees set the forks at the same width. Anything with a 16" front wheel or a 40mm fork (GK) is different.

How to replace the disk for this bike?

I responded in your other thread. It's a specific bracket set for a particular choice of calipers & rotors on stock forks & using stock wheels. Lots of info earlier in the thread if you read through.
