Lightest XS1100

Yep, another good way of dropping weight is junk the clocks, I didn't coz I wanted to keep the fuel gauge, I also like the look of the original clocks.

That cycle speedo does look really good, dya have any details, better still a link.

And looking at your 650 I wouldn't have trhought you needed our ideas on dropping weight from a bike

Here is a site with a bunch of wireless speedos..
It has been a few years since I did the 650 build and I guess they do not sell the model I used. Looks like more choices that I had.

I got a lot of the 650 build info from a site like this.

I am not too creative, I need lots of good looking stuff to stimulate me.

The search ideas have been helpful. I should have thought of it myself.

I have one of those bobber/rat bikes yall were talking about

The things that I've done:
Clip on bars
New rear suspension (slightly lowered end now as well)
Pod filters
Redone gas lines
New seat (http://www.xs11.com/forum/showthread.php?t=38753)
Got the bike with 4 to 1 exhaust
Removed fenders
Replace brake and rear turn signals
Removed center stand
and for style I put on gas tank net with a canteen in it and a gas mask ontop of my headlight

Fear riding fenderless

Hi TJ,
I had to carry a gas mask to school but that was in WW2 in case the Luftwaffe dropped gas bombs on us instead of their usual incendiaries and HE.
Better that you carry one just for style's sake.
But the fenders, man! Puttem back on! Without them you can't ride in the rain without peering through a fan of water off the front wheel and wearing 20 lbs of mud up your jacket from the back wheel.
Plus the front fender acts as a fork brace so your ride will run all wobblyarsed without it.
OK, A Tkat fork brace helps there but you ain't got one.
On the good side, you kept the rear suspension. That means there's less chance that hitting a pothole will bounce your arse off the seat to land on the back tire which will carry you forward so the back of the seat rips your nuts off.

Well sure, compared to a modern bike these things are portly. But 'back in the day', the XS wasn't even the heaviest bike in it's class. The XS and GS Suzuki were close in weight, the KZ was lighter, and the CBX was more. Given that the others all had lighter chain final drive, Yamaha did a pretty good job of keeping the weight down...

I know Steve! I'm just busting your chops! And I agree 100% that removing much weight is going to be a BITCH!

Of course, If I could go back in time to 1979, I could take 100lbs off my bike instantly! Just by letting my younger self ride it...

Swapping over to the swirly wheels from the later XS's & XJ's will save a couple of kilos each end.

[1234loft]

I really do not care for the swirl wheel, but I did not know it was lighter.
Thanks

Perhaps a light weight front end from a sport bike with good brakes.
The rear wheel has to stay due to the shaft, but the front could change.

Anyone know of a light low priced front end that is a good swap?

Hi Errol,
you sure about that? I mean, you actually weighed both styles of wheel?
I'm surprised because when I compared the weights of XS650 cast vs wire-spoked front wheels they weighed just about the same.
Admittedly a cheap bathroom scale ain't all that accurate but any significant difference would have shown up.

[TomB]

I know Errol has weighed his and I did too, I use XJ wheels on my 5K7 Euro Sport. They are lighter.

The swirly spokes are considerably thinner/narrower, so much so that its easier to fit Blue Spot calipers to XS11's with swirly wheels because they offer more clearance.

The XJ swirlies I use have a 16" rear which has the same rim width as the XS16" 3.50, whereas the Sport 17" swirlies have the same width as Standards, I dunno if this will make any difference to weight.

Over to you Errol

Had some previous discussion on brake discs here - http://www.xs11.com/forum/showthread.php?t=29334

There's a reply by Mathh about halfway through that says that SR500 discs are only 5mm thick as opposed to the normal 7.5mm.

That'd save some weight too!

[1234loft]

Thanks for the heads up on the brake disc.
I will check e bay for availability and $

This seat should be a bolt on and I believe you lose the fat grab rail in the process.

This under 3 lb rotor from 650 Central x3 will knock off a few pounds.

This under 3 lb rotor from 650 Central x3 will knock off a few pounds.

There are a couple of caveats attached to this rotor; it can't be used with Special front forks/brakes or used on the rear of any XS/XJ. This rotor has a shallower 'dish' and the two spacers seen in the bottom of the photo are to space the 'standard' front caliper brackets closer to the wheel.

They're also $140 a pop....

[1234loft]

Well,
I lucked out on the rotors from Mikes.
I have a special....glad I did not have to think about the $140 per rotor.

That seat has been for sale for a while. Has anyone seen a photo of one on a bike?? A special of course.
It just looks like the angle may not work? It could be the photo.

[jetmechmarty]

Steve,

Is there a replacement rotor for all 3 positions on the Special. Will the Brembo or another EBC rotor fit?
