Monster swingarm options

[dunlop0_1]

Is there an aluminium option for the early hoop type monsters?
Been scanning fleabay without any luck.

851 - think Paul Payne may have one tucked away....

[Jolley]

Yep, 851 is what I ran on mine last year. Usually come up on eBay for £100-140.

Try to get the wheel spindle with it though, as it is slightly longer.

[dunlop0_1]

Thanks gents.

[bradders]

defo on the spindle! and sliders...and adjusters...in fact get everything you can

Been on the search on here about swingarms and still couldnt find my answer so. Would a 900 aluminium monster swingarm fit my 583 dd racer??

[skidlids]

Yes Richard providing its from the 900 aircooled Monster and I think the one I spotted on ebay yesterday is the right one for the earlier models with the suspension hoop
I have noticed many Monster owners discribing the S4 model as a 900 and that one uses the later arm as its the 916 watercooled engine

Cheers, well dont tell everyone where it is, my bikes going on a diet after her weighing a 172kgs at snetterton with only about a liter of fuel.lol

3 on Ebay at the moment that I have seen
The one in the USA has everything with it, loop rocker, spindles, end plates, adjuster blocks, rear caliper, rear Master
There is another in Italy and then the one in the UK that has had an offer made on it

Well one I've put bid on is uk one. Shouldnt need anything else, right? loop is same right? If not i know a man who has one :)

Just unpacked one and put it in the garage. The one from Italy appears to have all the bits but he wantsm a lot for it although he will haggle. Might be worth a try.

Mine weighed about that in first season. Think I knocked about 12-15kg off it by the end of the second season... Swingarm, fueltank, wheels and battery were the biggest savers (along with realizing I didn't need 12+ litres of fuel!!)

My B bike was hugely overweight at some point. :D

Oh right do you want to sell it? :D

Must have been the chain under the seat champ ;)

Soon as I can its going on the bike. Hopefully in time for Oulton. I am not sure its value for money in the weight reducing stakes.

It isn't just the weight... It is a swinging weight. My rear was much more stable after the switch (probably because the swingarm wasn't slowing the reaction of the rear suspension so much).

That makes sense about the swinging weight. Never thought of that.

If I can stabilise my rear I will be very happy :lol:

Sprung vs Unsprung weight, innit.

Removing mass from rotating components - wheels, brake disks, sprockets, chain, tyres (where allowed) - has a much better effect as it reduces the energy required to rotate them so in theory you should get better acceleration, improved handling (due to lower centrifugal forces), etc.

Thanks,
never thought of that. So if you swapped twin dosc for single disc with the same stopping performance then you wouls not only get the weight advantage but it is also a benefit as its the unsprung (I think) weight.

Thats made me happier about buying the swingng arm!

which is why I went 1 disc - 5kg off was worth doing!

Before considering Alloy arms, I was considering disc weights a few years back as Bradders says its worth doing

I had already given up on the single disc option so couldn't save as much weight as Paul mentions. So I went to twin discs.

Prior to 2008 we had to use OEM discs from any production Ducati and there was some weight savingss to be had here, with the heaviest discs being those that were fitted as standard to the 600 Monsters and Supersports where as discs from later (say post 1999) were lighter

In 2008 I altered the rules so instead of the calipers being Free and the Discs OEM, I swapped it so the Calipers had to be OEM from a Production Ducati and Discs were free. Opening it up to after market discs such as EBCs, Braking, Galfer etc.

Andy Pike tells me his Armstrong Discs not only saved weight but also perform very well, the same could be said of the Braking Waveys that I run on one of my sets of wheels

[bradders]

have to say I'm enjoying the twin set up and not finding the limits (hence I'm too slow!) wheeas the single disc was on/off so much easier to find the limits!!
