Wheel question

[darrenptalbot]

I've got a choice of two cast rear wheels for my 1100. One has the brake disc attached to the wheel, one has the disc on a 'carrier' that is fixed through the wheel bolts.

Is there an advantage to either method?

I've bought them both, so that's not an issue!

Cheers

What's up with you lot?

Don't get stroppy ! It's too hot for that !

Maybe us watchers are a bit confused by your write up. Why not make it easy on our eyes, and post some pictures of your wheels, and then maybe someone might advise you.

You've discovered my weakness ... How the hell do you post a photo? It's on my phone, but can't upload.....

 

[Ian J Hartley]

If your at a computer, I use the manage attachment under additional options at the foot of the reply page. Allows you to upload one picture per post. Or you could use some of the online services like photo bucket and link to your post.

But from a phone. God knows how you do that. I would love to know myself.

Though in answer to your original question, the differences may well be as simple as one type is easier and cheaper to manufacture than the other. Less machining and all that. Or it might be the designer preferred that style for the bike.

Hopefully someone more knowledgeable than me will be along shortly to advise.

Unless this works .....

 

[darrenptalbot]

Will work on the picture!

I think iI've got one wheel from a k1100 and one from a r1100s .... If that helps?

 

[Ian J Hartley]

Nope

Nice try though

 

[darrenptalbot]

Trying from the iPad ......

 

[darrenptalbot]

Ok, so upside down. Good enough for government work!

The wheel with the insert has the brake disc attached to the insert. There are no attachment points on the wheel casting, unlike .....

The other wheel, which is as the front, with the disc attached to the wheel casting.

 

[Ian J Hartley]

The K1100 wheel has the disc secured through the same holes as the wheel bolts.

The R1100s wheel has the disc mounted on seperate spigots.

I could be wrong, but I think it is nothing more than simplicity of manufacture, and the design of the wheels.

There is a lot more commonality between bikes of the same series (R) than there is across series (R to K). So for the R series they probably went with a different design for the wheels and discs.


I got all this from looking at the parts catalogue before you posted pictures, so most is bollocks. I don't think that wheel is from a K1100. They both look like R1100

I can see why you need advice, on the surface they look like two rear cast wheels from an R1100S. But with different disc mounting.

Can you make out the year of manufacture from the casting impressions. Could be one is earlier than the other and there was a design change mid model range.

Anyway, I'm out of my depth, just hope someone comes along with the answer

They look similar, but no spigots on one wheel. Still, if it works for one bike, should be ok on another!

I'll check once I've put the kids to bed

 

[Ian J Hartley]

There are 4 different part numbers for R1100s rear wheels.

Standard tyre
Standard tyre with ABS
Wide tyre
Wide tyre with ABS

Could be you have one standard and one wide, which may account for different disc mountings.

 

[Ian J Hartley]

You could try this thread, reference wheels. Lots of information concerning differences.

Excellent, thanks

 

[Ian J Hartley]

I'm going to stick my neck out here, but the more I look at the wheel on the right, the more it looks like it's from a K1200 with the ABS speed sensor ring removed.

It's the nearest match I can see from the picture and description. If I'm right, then the reason it's the way it is, is because of the design of the abs ring and speed sensor fitting. The sensor sits in the vertical plane looking down on a pretty substantial cast ABS ring.

If you look it up on the online parts, you will understand what I mean.

 

[darrenptalbot]

I see what you mean.

I guess it's all down to aesthetics then on my choice!

Thanks for the help
