First Gen GSXR1100 Suspension

[Roger P.]

Is there enough of a benefit from fitting such old components (1987)? Had suspension tech progressed enough in 4 years to make the swap worthwhile? There is a batch of parts going cheap here, and my GS has yet to elicit any response from the classified ad, so I'm thinking I might just turn it into a long term project, starting with the suspension. A 160 rear and a 110 front don't seem to be much of an upgrade in size, although I must admit the radials on my Bandit are light years ahead of the old bias hoop on the GS in terms of inspiring confidence in the turns, so I would love if it the GSXR wheels could give the same feel. He is also selling the front as a complete unit with triple, calipers and clip-ons with controls. I could have everything I need to swap over, including the rear tire for about $500.

Damn straight it's worth it. You're going to bigger stronger forks with electronic antidive (which apparently works much better than the GS set up as it doesn't involve the brake system) four pot calipers on floating rotors (one GS rotor weighs the same or more than BOTH the gixxers) and radial, wider tires. Even using the stock 1100swingarm it's a nice nice upgrade and looks almost bone stock on an 83 1100E as the early wheel casting was nearly identical to the GS.

500$ seem to be a bit high.
I have the same kit here but for a 1986 gsxr750.
I can PM you pics.

500.00 is a good deal for all the stuff...if it includes rims, brake calipers (all 3), rotors, forks and triples. The 750 forks are shorter than the 1100 forks, so be cautious about ground clearance.

Even though the early gsxr forks are damper rod units, they are superior to the GS components hands down. I had 1st gen 1100 bits on mine, and sold them to Jim (poslayr)...I am in the process of gathering running gear (to include swingarm) from 2nd gen bandit 1200s to mod for fitment to my GS.
Modern cartridge forks, 6 piston calipers up front...gonna be awesome!!

Good luck and post some pics of your bike!!!!

Yeah, I'm a lazy typist. Anyhow, there's enough good people here and at oldskool that it would be stupid not to ask everybody.

 

[jwhelan65]

Agreed the price is more than fair.

 

[salty_monk]

Same bikes....

It's a bit of work but definitely gives it the modern feel.... Mine is the 5.5" rear wheel with a 170 but easier to go 160 with a 4.5".

I'll vouch on the work....

That looks cool.

I want to upgrade front and rear ends on one of my GS1150 EF (sans fairings) but am a bit worried about the 4" trade off of fork length going to 90's model GSXR front ends. Surely the already front heavy bias would get even worse and change rake and trail by default of the 3.5" lowered head stock. (assuming .5" gained back in change from 16" to 17" wheel)

You can fit a stepped Honda top triple to gain some extra height on the USD forks. GSXR1100 forks are longer to start with. 1150 should be same as my 750.

Roger is it the one on Kijiji here in Ottawa because his price is not 500 it is a lot less.

PM sent.

The stepped Honda triple clamp sounds like a cunning plan. Still looking for GSXR1100 front end. They don't seem to come up often.

I did a google and ebay search for 'stepped Honda top triple clamp' but got nowhere. Any chance of some more clues.. model type age etc?

Cheers

Have decided to run with cut down fork springs and spacers and the Monster shock for the new old GS1150 I just got. That leaves the road clear for a more betterer upgrade for Baz (the old old GS1150)

2002 cbr 954 step down tripes with Vortex billit top triple

 

[Colin Green]

Thanks posplayr

"2002 cbr 954 step down triple and a Vortex billit top triple" sounds like more Rockinghorse droppings to hunt down :lol: Don't suppose you know what forks were used to suit the clamp?

I got 2002 cbr triples off of ebay for 50 bucks. I had to change the bearings to suit our bikes and weld steering stops but nothing major-well, welding was sourced out.

Nice thing is your wheel spacers for a gsxr front end is the same if you are using a complete 750 front end like I did at least for a 93 gsxr front end.

In Classic Motorcycle Mechanics, there is a guy that used a K4 gsxr front end in his cbr triple tree.

 

[saffa]

just use a set of gsxr750wp/wn forks. theyre a direct drop in ,stem,bearings and steering stops.

ive had them on my 1100ET for years now and still havent ground out on anything and thats with a stacked 4 into 1 system.

 

[Colin Green]

Thanks guys. Found one on ebay that's at $79.

Does the 954 top clamp match the GSXR bottom clamps (750 only? any limitation on what year?)

Interesting that many GSXR front ends are missing the top clamp anyway.

it looks like the 954 clamp will allow the forks to be set down by about an inch (maybe another 3/4" if forks are set down flush with top clamp... how then are bars attached?) and another 1/2" is gained if a 17" wheel is used that. That makes for 2&1/4" of the 4" difference (between GS1150 forks and GSXR forks).

It seems that the front would still be 1&3/4" lower or am I missing something? If radials are used is the tyre profile higher?

 

[salty_monk]

You drill the top clamp & add risers & normal bars not clipons. It's likely that you will still end up with some drop at the front unless you get a custom triple made up.
