Xs1100r

I fitted my forks with some proper springs and emulators. I am more limited than it is. I think the weak point is the 37mm forks. Bikerphil's FJ fork upgrade probably helps more than anything.

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:

I guess I don't see how the gussets would help that either.

Yes, I'm aware of the mods you've done to your suspension and I am highly considering the same path for the forks as I would like to keep them looking stock.

Hoping one of the guys with an RH will chime in on the stability, or not, that the gussets and bracing do, or do not, provide.

I'm not entirely sure the gussets and bracing would or wouldn't help either.

I'll let our Brothers who own and ride the RH's comment on that.

I'd like to see how well I can get my SF to handle aggressive riding and use my '80G Full Dresser for touring.

I swear you can make that thing rock! If I see you at a rally, you may try mine. XS Southeast is your best bet.

Problem is, the swingarm needs to be a bit stiffer too, a lot of that 'hinge' effect seems to come from back there.

As big a that thing is, I have trouble seeing that. Maybe the pivot point? I'd have to take a closer look at that.

I think Crazy Steve has a good example of a reinforced swingarm, couple other fellas did it too.

Edit: If you look at the swingarm on the right hand side it appears to be pretty flimsy.

I wonder if the R's got any love in that department, for example, heavier stock ?

There's really no room to add any support and keep it stock looking.

My two cents

It doesn't seem to me that Yamaha would just throw the gussets on for fun.
Many of the 70's bikes needed gusseting . Kawasaki triples the z1.
Most big inline fours did.
Spindly forks and wimpy swingarms were a lot of the problem,
Who remembers the term"flexi fliers"?
(I don't want to reignite the fork brace debate).
For most riders it isn't too much of an issue.
After all these are 600 lb bikes,
But I have noticed if you toss it into a corner hard and then change directions it will act like a spring ready to uncoil.
Lucky me, I have a deserted road race track close to home.

As for the additional weight... Eat one less meal,
Your safety is more important

I think this might be more effective than a swingarm brace. That swingarm looks pretty darn stiff to me. I'd look to the pivot area if anything.

Thanxs Marty, I'm going to try my hardest to make it to XS East this year which will be my first one and if somehow I can arrange Southeast post in that thread.

Meanwhile, I'll be searching for a front & rear swirled set of wheels.

I agree, especially about the meals.

Throwin' around this Old Iron aint for the faint of heart.

+1 on the 'spring ready to uncoil', but remember too that these bikes accellerate quickly, corner and stop......just never two of the three at the same time.

The "hinge"?? yes the hinge does appear tamed on the XS1100R.

I own two Standards, one with steering head braced, frame braced, monoshocked rear end, bigger forks, massively lightened, and I own a stock Standard so I have some pretty good comparisons.

I hear what you're saying about the shaft effect and cornering, what I use as a measure is the high speed straight line weave, at 130mph the stock Standard could start to weave, the monoshocked bike doesn't and the stock XS1100R doesn't, I can definitely feel the difference. This is all subject to getting your forks and rear shocks in top condition, when I originally rebuilt my Sport it handled crap due to the rear shocks, I now use Koni's.

Marty, all the XS1100R and XS1100S (Sport) models had gold wheels, and gold tank, seat and panel badges, that was all though, not like the MNS's which had lots of gold trim. I have XJ1100 wheels on my Sport, I like the tubeless wheels and also like the black colour rather than the gold.

Marty's photo shows the cross tube bracing and also the underframe brace mounts, there is a large heavy brace bolted to this bracket, I have the brace but can't use it with the Kerker, it goes outside of the stock exhaust 2+3 pipes but won't fit over the Kerker collector.

Heres a swing arm with decent bracing one of the UK lads has done
