GL1100I on a diet?

Postby lake_harley » Sun Jan 31, 2010 1:03 pm



I just can't seem to stand the idea of leaving well enough alone. To me light weight translates to better performance, handling, etc.. Has anyone made any effort to reduce the weight of their GL1100I? At 650-ish Lbs. I would think there are ways to shed 25# or more but quite honestly after looking the bike over I can't see any significant areas to be addressed. There are ways I can see to lose some weight but the cost and effort would add up and I don't think it would end up saving very much weight. I do want to leave the bike fully dressed. Is there any potential of savings in the fairing, as it seems rather heavy? I'll probably take out the radio, since the exhaust and wind are the only music I need :D

You might have better luck know what kind of gas mileage you get and only filling half the tank. It seems quite large to me, very nicely located. I haven't had my bike very long, but I haven't seen any extra weight. Unless like you said, you start removing things that are expected.

The radio/accessories, air compressor/gauges for the air shocks (I just bought and re-installed one in my bike). Maybe remove the fake tank, and replace with some custom bended aluminum/sheet metal to make it look nice again. There is so little. Maybe some extra metal, if you have the rack ontop of the trunk or bags. The center stand. What else?

You'd be surprised with that fuel tank - I often wish it was twice the size. In and around town, I get around 120 miles out of a tank. On the highway, I can approach 160. I'd love it to get twice that before having to find a gas station.

Thanks for the replies and discussion. I had another GL1100 a couple years ago and traded it off, mainly because of the weight. I'm about 5'10" and 155# and it was a struggle to move it around. I don't really recall it feeling all that top heavy or anything but any reduction of weight would make it just a little bit easier to back it out of a parking spot, roll out of the garage, etc. Don't even suggest I buy a newer Gold Wing with reverse......I'd quit riding motorcycles first.

I have had problems backing my GL1100 before, and I am now very careful to park so that I can always pull out forwards. At least until I move to a 1500. :)

I had found the newer GW a bit "bulky", and didn't know if I could handle them.

Then I went from my Honda CM400T to an ACE Tourer 1100, which I found had plenty of power. Got very used to it over the last 15K Kms, even 2-UP riding. I bought my GL1100A for winter riding (collector bike/insurance {lower rates}) so I could enjoy, so my wife and I could enjoy some rides when we had good weather, along with a second bike for summer rides with my brother (no bike). So far, I've found the GW satisfactory. it doesn't compare with the cruiser, it's different, but it is nice for the both of us, and we are over the weight limit.

If you're only 150#, I don't know WHY you would find this bike lacking. I would think that any lack of power is due to the age of the bike, so if you had it fully tuned, you wouldn't be able to do anything better than that. A little bit of weight reduction I don't think would do much.

Good luck, and keep us informed.

You should also keep in mind that the 1100 loves revs. Lug it down at 2500-3000 RPM, and it will accelerate like a slug, and vibrate as it does so. Rev it up higher well into the power band and it will just fly. Don't be afraid of revving that 1100 cc's up into the 6,000 and 7,000 rpm ranges - it's quite happy there!

I'm not concerned about power or acceleration. My interest would be to make the bike a bit easier to manuver/back up for a scrawny guy like me.

Ok, this is VERY nice to know, and that must be why they gave you a tack with the bike, so you can follow your RPMs better.

OK, that makes sense, now we know why you want to do this. If you can't remove weight, what do you all think adding weight on the bottom of the bike? Maybe 10# of lead by the kick stand?

Honestly, I don't think the bike is that difficult to maneuver at slow speeds, once you get used to it. When I first got my 1100, I was coming from an extremely maneuverable and light 400-lb GSX-R750. I'm not afraid to admit that the weight of the 1100 intimidated and at times scared me. I felt like I was riding a truck, and anything below 5 mph, I stopped and walked it around.

A few years down the road, an MSF ERC course under my belt, and I'm quite comfortable riding my 1100 slow right to the point where it is about to fall over. I will U-turn in just about any road without hesitation and without putting my feet down. The bike is actually extremely maneuverable, with the center of gravity very low thanks to the horizontally opposed engine. I can fling it around twisties almost like a sport bike. And I'm not the biggest guy - 6 foot, around 175 lbs.

Last summer we had a 4th of July parade in our neighborhood, and I rode behind with my wife on back, at walking speed, for about a mile and a half. I wouldn't have been able to do that when I first got the bike. It just takes practice.

The only thing that I do hate is moving the thing around by foot in parking lots and so on, especially pushing it up inclines. Adding weight to the bottom is going to make this even worse. So as I said previously, I make a point of always parking in a way that I don't have to push it out by foot.
