Certainly a wider track width (centerline of bike tire to centerline of sidecar tire) creates a more stable rig. What track widths are you running? And what wheelbase?
Is there maybe a rule of thumb ratio between track width and wheelbae here?
My presnt track width is 60" on a K100 (CAN'T REMEMBER THE WHEELBASE OF THE BIKE ) _________________ Claude Stanley

In a story in a Dutch bikemagazine I found the following facts. I hope the conversion to inches and lb is done right.
1 inch = 25.4 mm
1 lb (UK) = 0.4536 kg. Can't find a "USA or Canada lb" (Btw is that called pound and is with or without a "s" if it is more then one?)
GTS1000-SideBike MegaComete:
track width: 1345 mm 529.5''
wheelbae: 1540 mm 606.3''
Caster frontwheel (trail) adjustable between 0-40 mm 0-1.575''
Caster sidecarwheel (trail) adjustable (sorry no numbers)
Lead sidecarwheel 445 mm 175.2''
Camber sidecar and front wheel adjustable
Toe-in sidecar wheel adjustable
left steering effect 5 degrees
right steering effect 10 degrees but the steering effect is adjustable
Compleet turn left: 9500 mm 3740''
Compleet turn right: 6400 mm 2520''

sidecarmaniac,
Would the information you listed for your GTS1000-SideBike Mega Comete, also be the same for a 1993 GTS and a 1998 SideBike Mega Comete?
I noticed that in the picture looking down into the sidecar, you have seat belts. Were they a factory option, or did you install them yourself?
If they were a factory option, about how much in US dollers did the kit cost?
Did you have to modify the seat in any way for the belts?

But one of the dealers uses still the same technical numbers today. When I've to replace something I alway's measures distances from the part to some fixed point. I also try to count the turns from or to a maximum adjustment point. Both, GTS and MegaComete are not produced anymore.

Bruce | I've done it by myself. Bought universal sets from the carshop. Not automatic adjustable ones because the drum/spring units are to big. I did use metal plates behind the mountingpoints wide enough to prevent breaking out of the polyester in case of an emergency. Used also nuts that don't come off. There was no need to modify the seat. I placed the belts for my sons. For an average adult the position of these belts is to low now. But soon, because the boys keep growing, I've to move the upper mounting points a bit upwards.
By our law a helmet is needed for sidecar passengers, the belts are not needed. Imho for kids the belts are more important. _________________ www.sidecarmaniac.nl |

John,
Thank you for posting the specifications on the GTS / Mega Comete and for the information on your seat belt installation.

Had the tape measure out last week end and measured the track on my rig. I measured from outside of tire to out side of tire, so subtract probaly 6 or 7 inches for tire width. Track is 61 inches, out side to out side (or 55 more or less centerline to centerline.)
Also measured the toe in, I'd never measured it before and ifgured if its working don't screw with it, anyhow toe in is 3 inches, guess that explains why sidecar tires wear so fast. _________________ Mike Currin

Using a Vermont tapemeasure in a snow covered cold barn I came up with 55" track width from centerline of rear motorcycle tire to centerline of sidecar tire. Now that could change if I measure under warmer circumstances. _________________ Larry Miller

FJR/RDS Track width 60" OD (probably 51-52 inches center line) and Wheelbase 65.25 centerline.
That looks like 5 inches longer then the GTS. _________________ Corret me if I'm wrong, everyone else does! |
