Single sided swing arms?

I think they look awesome. 'speshly on MVs, and 916s and the like.

The radial speed at the bearing maybe higher compared to a conventional smaller OD layout and have been known to lock up on Ducati's

...they were mainly for endurance racing on bikes like the Elf ????

Sounds like a fun spectator sport.

Will endeavour to pop in and say 'Hi' and have a beer to rid me of all further thoughts of the Hart v Dworkin jurisprudence debate. (Sorry to continue the thread hijacking...)

Is a production run from 1994 to 2002 a mere flirtation??

This is one of the modern classics you're talking about - can't have been all bad...

Weight. They weigh more than a conventional swingarm to maintain torsional stiffness and therefore create more unsprung weight making the suspension work harder. Also the lateral stiffness of racing bikes is now factored in as suspension, and it is harder to engineer a SSSA with adjustable or different lateral stiffness.

I've had two bikes with SSSAs and the best thing about them was being able to put the bike on a stand and remove the rear wheel to get a new tyre fitted, without screwing up your chain adjustmnet

They are great for rear wheel cleaning as well for those with out a center stand.

A friend wanted to fit a VFR400 SS swingarm to a FZR400. The VFR one weighs a ton - must by twice as much as the Fizzer one. Lots of unsprung weight which is bad

some are worth their pitfalls & some aren't. intended purpose equates to preference of choice. not keen on them myself but this RSV mille is tasty with a single. the flying kiwi team used one in the bike

Well why don't you own one of them then ya twit!

Your vifferari looks choice!

I've always like the single swingarm look...on any bike. Ducati 916 being a old favourite!

Pretty much been covered,but I still gotta add my two cents

Very heavy and flexi (even with all that extra weight),but won't place any more stress on bearings and frame than any other design (unless the wheel has a big offset),hard to Imagine,but think about it,the contact point of the tyre is still in the same position in comparison to the swingarm pivot and wheel bearings (if the wheel is offset correctly)so the stresses will be the same.The only part that suffers is the arm itself.

**Sketchy_Racer** · 29th October 2005, 07:24

heres my one cent,

having the weight of the swingarm may help to balance the bike out eg the bike may have to much weight on the right side so, they put all the swingarm weight to one side making a perfectly balanced bike.

but then there are all the down falls stated in previous posts, but they still look awesome!
