Xs1100r

[Eveready1100]

T.C., Yes a lot of guys over here did think that they came with the big tank, but in all cases, they've been swapped over at some stage. Ex factory, they all had the 15 litre Special tank.
In saying that, it probably wouldn't have been a real hassle getting the dealer to fit a bigger tank if the customer asked for it.

Other than the tank, Jim's (ozlad's) Rh only differs from stock with the horns, rack, caseguards, seat (been recovered but stock shape), 4-1 exhaust, the little dash panel above the guages with the clock mounted in it, and the sidecover badges have been changed from the normal 1.1 to those XS eleven stickers.

DaveyG, the regulations regarding production bike racing back in the day were very strict. The bikes had to be run absolutely stock standard, with no deviation from the shop manual.
There was one year when BMW won the six hour with the R90 and they got excluded from the results because the fork spring preload spacers were found at to be fitted below the springs instead of on top, as per the shop manual.
So swapping tanks was definitely out of the question.
I've heard of other cases where bikes have had the fuel tank blown out slighty with compressed air to give a trifle more capacity, but these were discovered during routine scrutineering, where everything is checked, firstly with placegetting bikes, then right through the field till they were all checked and official results were then posted up (sometimes, it took weeks)

Not just the badges Errol, the side covers are from a Standard.

Changing the tank is a popular mod with longer distance riders, heres mine with normal running mode


And changed out the tank and seat for a recent Portugal trip


Another difference on the frames is at the rear end, the XS1100R and XS1100S have simple ends to the tubes, no indicator mount big holed bracket, just flattened and drilled for the mudguard

So, was this bike available in both Europe and Asia?

if one was to add the gussets and bracing, what would be the optimum weld procedure of choice ?

Optimum would be TIG.

Hi T.C., if one was to add the gussets and bracing, what would be the optimum weld procedure of choice ?

That which you are best at.
From a strength standpoint, if the welds are done properly, there will not be a meaningful difference.

Yeah, both Europe and Oceania (Oz + NZ), not sure how much of that includes Asia, but there were Japanese models, yes I know they're ALL Japanese models but sold on their home market if you know what I mean.

The 5K7 in my sig' is my XS1100S or Sport in Europe, the same as the 5N5 or XS1100RH in Oceania.

+1 on TIG. I use Mig coz its what I have and get good results with care.

[jetmechmarty]

I notice the Oceana bikes are trimmed in gold, and the European ones black. Was this how they were delivered?

Thanxs all. Most likely will use MIG as that's what I presently have but by the time I get to the build I may have a TIG set up.

Do you ride at such a level that all that bracing is necessary? Me thinks you can push an XS1100 very far before you get to where it hinges.

It also adds unnecessary weight if you do not need it. You could easily add a good 5-10 pounds without thinking about it.

If a little fabrication will help eliminate the effects of " The Hinge "
I will be able to ride at a more agressive level, safer.

I'll shed a little weight here or there to help compensate for the added gussets & bracing, but IMHO these engines won't notice it.

Actually adding the Standard tank adds most likely what the gussets and bracing will.

Do You Folks from across the pond with these gusseted/braced frames feel the hinge effect ?

[jetmechmarty]

I run it pretty hard and I haven't found a hinge. The heavy springs and modified forks helped a lot!

I am assuming you are talking about the "shaft effect", wheel tucking under and raising the frame during acceleration. I don't see any reason why the gussets would help that at all. Only way to "fix" that would be to weld the swing arm in a fixed position.

Heavy springs help with that. A lot!

Yes there are things that can be done to help the issue but adding frame gussets is not one of them, unless it is to hold the swingarm in place.

The shaft effect can be finessed with the throttle and front brake.

What I'm refering to is the steering wobble that is described in this thread:
