richie moore qustion

Hello , does anyone know why i cant get on to the moorespeed website. And when ive tried ringing the number does not exist. Has he gone bump or sumat ?

 

[Shurv]

Richie's an engineer,not a computer wizard, he probably hasn't realised it's down.

Just spent a long time looking around his site.

Under Useful Links, he includes "BMW GS owners Club"



Moved cursor over the link and it comes up with www.ukgser.com

The very same! I did the GS Challenge in Leydsorp RSA with him as my buddy on his 663, see pic.
Sadly that was the last run of that great event as one rider was tragically killed on day 2.

do you reckon theres much advantage to fitting a r1100 gs paralever to a r100gs like hpn does, if so what is it ? other than very slightly longer giving a little more travel.

 

[Beemerboff]

From a dynamic viewpoint there is none - a paralever acts like a infinitely long swinging arm anyway.

But as a tool to extract a great deal of money from the fashion concious or the gullible they seem to perform excellently.

 

[Shurv]

Isn't the paralever arm heavier than a mono one? If you want to go tubeless then a para arm is a good idea,other than that, get an extended mono. 50mm is sufficient unless you are extremely lanky or want to do serious off roading.

I have got the 1100 swing arm and bevel box fitted to mine
It it is a fair bit lighter has a decent rear brake
The drivshaft is replaced with the 1100 one so no problems there anymore
Suspension is in a different league

I would say the overall difference is like night and day.... A massive improvement

Mine does do some proper off roading

And has the scars to prove it

thanks for the info chaps, id love to do the monolever conversion but the cost makes me want to try something different and cheaper ie the gs 1100 paralever way , still cant get why it so much better than the r100gs paralever susspension according to some , other than the fact that the shock is mounted diferently. Is there much differance in length.

1100 swing arm mod is far more expensive and complex than a monolever conversion

 

[Canuck]

So I've heard... but if you are interested in the 1100 get in touch and I may know of a man who may have a spare part or two hanging around if you do it yourself, or are not interested in shipping it to HPN.

I think this depends on what bike you start with and what you want to get out of the mods.

You are right if you start with a monolever g/s.

If you are starting with an airhead paralever, then piecing together all the monolever rear, to then have further work to extend it - comes out quite expensive/time consuming.

While the 1100/1150 rears are "relatively" cheap and easy to find, will require no extension work should be a reasonably easy bolt on.

However there are a discussions on ADVRider that highlight problems with rear wheel offsets.

This route also gives the option of fitting a rear disk brake.

From my understanding of other threads the 1100/1150 rear length equate to approximately a mono + 100mm or GS para + 50mm. Which means that you have a tall badass dirtbike, which may or may not be what you are looking for.


I am piecing together the bits for a R1150 rear onto an 80GS para, on the above thesis- but am yet to start the work so there is hope value in the comments above.....

The seller is a little vague and it is not clear just how HPN the bike is but this might be worth pursuing: http://cgi.ebay.fr/BMW-GS-80-R-1983-type-HPN-/170919055011?pt=JG_FR_Motos&hash=item27cb91cea3

The 1100 rear end is very easy and cheap apart from the offset needed to bring the rear wheel in line. I can't remember exactly how far out of line it ends up but I seem to remember its around 100mm which is a hell of a lot. There's a company in the states that will redrill the spoke mountings to get the angle right and I think there's a Dutch company that can also do it. You will need the adapter for the airhead gearbox output flange to allow the 1100 driveshaft to fit.

Being completely honest. Unless you need a full on rally bike why would you need more than a paralver back end with a decent shock?

Not many people have tried a well sorted 1100 rear end
Take my word for it there's no comparison

It's easy to extend the swing arm and driveshaft
The 1100 rear needs a whole lot of parts to be fabricated
Thats why you see so few

I messed about with an 1100 rear end in a project bike a couple of years ago.

Apart from the gearbox adapter at 300 Euros there were two main stumbling blocks:- The top shock mount and rear wheel offset everything else was pretty much just a bolt on with a few minor parts to be made.

The rear wheel offset was the biggie

The bike does end up very tall. Garry H had a lovely 1100 rear end converted Airhead a few years ago, he kindly let me sit on it. I was riding an 1150GSA at the time. Garry's bike made my GSA feel like a light weight moped. It was a serious bit of kit though but not for the feint hearted especially if you were going to ride it off road.

There must be a limit to how much the rim can be offset before the tyre hits the shaft housing. Even on GarryH's bike the wheel still appears to be off the centreline.

I understand that the 1100 paralever is preferable to the 1150's which is shorter.

You have to fit a narrower rim and tyre and even then it isn't possible to remove all of the offset. It's all compromise. You also loose the battery mounting position and the tool box.

Garrys picture shows just how much it's pulled over.

I would have liked to get my hands on an 1150 swinging arm to have tried the two side by side. I think the 1150 has more offset which may make it a better solution. even though it is slightly shorter. The big advantage with the 1100 rear end is that the torque arm fits straight into the para GS machines torque mount and it all lines up with the 1100 parts.
