helpful, thx
My bike is on a (slow) truck coming from Austin...it's in AZ now. My build project included losing the center stand anyway. Seems like one of the complaints of the CB1100 is that it's rather "portly." Being the weight-nazi that I am, I plan on a diet for the bike. Looks like it won't be hard to lose 25 LBS. BTW, I'm not trying to turn this bike into a sport bike (I have one)....just trying to optimize its potential without destroying its character or looks.
I have tried to make my bike the most pure 1980's look I can- combined with the best performance.
I always like watching build threads- so make posts so we can see what happens with your bike!!
I've had several cars that I have gone *nuts* on weight loss. But this bike isn't something you are going to loose anything remotely close enough to make any difference in performance on- especially given the cost.
I removed the dumb side trim under the seat- no need for them, look silly, not true to the style and age of the bike. Slight weight saving.
Different battery could save you a couple pounds, not much. Lipo don't like cold weather though.
You can buy an aftermarket aluminum but works same as stock swingarm from Samurider.com that drops weight. Awesome piece- but not cheap.
Easiest weight loss is in a full exhaust system- and will gain performance.
This bike will never be anywhere near 'lightweight', nowhere near great 'handling', nowhere near 'powerful'...compared to the best in each bikes of those categories.
That doesn't mean you can't improve on each- and doesn't mean it isn't a great bike.
The combination of look, comfort, combined with modern fuel injection, gearing, better frame design, brakes... to me is *perfect*.
The bike just needed a little help from what Honda built. But as a UJM- we each can make it our own 'universal' way.
Personally I absolutely would not screw around with different wheels, upside down forks, etc for that goal, but that's just me. More chance of screwing things up, money, time and work spent- for no real benefit.
I prefer to focus on what the bike is- improve those attributes without compromise.
I upgraded to, and highly recommend- the 2017 forks as they are much better than what the earlier bikes have. Others have followed after me and also give the upgrade a thumbs up.
I installed Ikon rear shocks (Ikon is Koni backwards- they sold off the motorcycle division in 2001 so the name was changed in a simple way- but they are Koni shocks). You can call or email them to get different spring weights if you want, various different spring caps, spring colors, adjustability options, etc.
There are several other brands of shocks you can buy- these just looked most period correct to me, and backed by a company with a storied history of making shocks for race cars since WWII.

On my bike- I have a 4-4 exhaust sitting here waiting to be installed, and some secret parts currently being made overseas to bring the power up yet again.
Old pics & old dyno compared to a stock 2017.

And here for the sound is an old video of the 4-1 on the dyno, muffled by the ventilation hooked to the muffler, fans in the room, and small indoor concrete room itself- but still sounds good. Better soon on the 4-4-

good looking bike....and great HP/TQ gains too....
25 LBS weight reduction is undoubtedly attainable...at (around) 5 LBS per HP, that's the equivalent of gaining 5 HP without getting into the motor. It all comes down to power to weight ratio.....and what you want your motorcycle to be.
