Ok

C'mon lads, I know you don't like listening to my limie accent but you could at least listen when talking about this bike

Hi Tom.
I have an 80XS1100SG. Currently it has the stock 16 in wheel. Exactly what parts do I need to run a 17 in wheel on it? Stock or custom (what dimentions etc.)? How much trouble / time is needed to switch back & forth?

Limie accent!! .......the bike called limie accent?? ..........from a Brit? ......never mind, jokes never my best skill



Brent, as the lads here say, usually going from 17" to 16" is how folk go, do you want the 17" for better gas mileage?

Obviously the wheel, and the steel torque plate from the 17" wheel bikes and their wheel spacers. The caliper and caliper carrier are the same.

If you don't want to use the different steel brake torque plate you can bend yours to fit the swing arm peg and use washers to make sure the caliper bracket fits over the disc centrally.

Here are the different wheels and spacers
This is the Special


The bearing housing on the Standard wheel protrudes further out than the Special wheel bearing housing.

This is Standard




Or you could go the long way round and make up your own parts, heres a combined bracket/torque plate for holding a front caliper on the rear wheel

Brent,

Why the 17" wheel? Is it even OK to run a 130 mm wide tire on a 2.5 in rim? I wouldn't do it.

IIRC the first number in the tire size is the width in mm, and the proper tire size for a standard on the rear is a 130/70-17, so I would have to say that not only is it OK, but pretty much the standard.

I don't think you'll find a tire manufacturer that says it's OK to put their 5 in wide tire on a 2.5 in rim. I'm pretty sure they recommend at least 3 in. IIRC, there are 25.4 mm in an inch. I'm not trying to start something, but I thought it worthy of pointing out.

Actually the ORIGINAL stock tire on the standard was a 4.50, and a 130 is pretty much the same width, but not as tall as the original OEM tire was, so I'm pretty sure your incorrect since Yamaha wouldn't have spec'ed a tire that the tire manufacturers would have considered unsafe, especially on a bike that was taken out and raced on tires of that size. As a matter of fact I believe the rear rim on the goldwing of the same era is about the same width and uses the same size tire. The thing that makes getting a tire that works for our bikes difficult is getting one that can handle the load in the 17 inch size, for some reason a lot of them seem to be rated for a much lower load than is needed for the XS11.

Why? Besides, I just went and measured and it looks like the standard rim is about 3" wide

Hey Marty, you could always talk Brent out of the 17" rear wheel mod and into the 750FD upgrade, the ratios should be pretty close between the two. The 17" rear wheel raises the bike though.

(?) Were you measuring from the inside of the rim, side to side; where bead of the tire sits down into?

[BA80]

I was measuring from the outside because the tire is on but calculating where the inner tire surface contacted. That's why I said ABOUT.

The special wheel is 3", the 17" standard wheel is 2.5".... and the original 4.50H-17 tire is 5.25" wide.

And as I recall the 130/70-17 is about the same width but a little shorter in height. Which is why I say the Marty is mistaken as Yamaha would not have specified the tire they did if there was a problem with that width tire on the standards rim.

[trbig]

That's nuthin'! I've seen kids putting 6" wide tires on 10" wide rims on their cars.. That's so cooolll... lol.

[jetmechmarty]

I'm looking at what the tire manufacturers recommend. Have a look. I guess tires have changed over the years. It's the tire manufacturers that recommend the 3 in rim for the 130 mm tire. I look at that pinched tire and it bothers me.
