Inverted front forks?

[gav]

Personally I'd take any information offered regarding suspension and handling from a TL1000S owner, with a grain of salt. How good is that rotary rear shock, mate? Why does the R1 have underseat exhausts yet Rossi doesnt get it?
AS for a claim that your capable of flexing the front forks enough so theynearly hit the headers? (your forks are bent, if thats the case...)
Its all marketing hype.....

Obviouly your one of these low intelligence types that are name callers to hide the fact their brain on regesters total lack of thought and consequences....okay...my TLs runs ohlins rear shock + robert taylor rebuilt front end with taxxion valves and the correct rate springs for my weight and bikes weight....inside of the tubes is coated with very low drag ceramic coating for less stiction...and low drag ohlins fork seals and dust seals...
So when you remove your foot from your mouth...why have u accused me of posting that I can brake hard enuff to make my front wheel nearly hits the headers??? I didn't post that.....
and yes....it is very very possable with conventional forks
do a rolling stoppie from about 50-60 kmph...and get some one to video tape those conventional forks on your honda....and watch it...you might be very surprised



Ps:underseat exhaust are power robbers common knowledge...

Thanks for your reply, however note that I didnt "quote" you, the flexing forks is another post, funny how these same forks are good enough to run on the WSS stage, AMA and BSB for many years, but not good enough for the road. Yes the forks may flex, but who says this is a bad thing? And why would I feel I had to do a rolling stoppie from 50-60kp/h? You may be aware that alot of the GP and WSBK teams are now trying to dial in controlled flex, but maybe these riders arent as hard on equip as some of the posters on here? Suprising that Suzuki couldnt find fault with rotary rear shock to start with and bin it before it ever made production.
ps Name callers? Me? check my post again sunshine, no name calling necessary

Oh what the hell....

the flex they are after is from the head stock...for feel as the 16.5 inch rim reduces feel...as does 6o profile tyres seen on a few bikes in recent years..
suzuki's problem is they came up with a brillent concept for the TL...but when everything needed to be engineered they ran out of space for a conventional shock linkage...so thats why they had a small diameter spring place along the side of the engine and used the rotary shock for damping...the spring and linkage provided the digressive control required of a road bike and the rotary damper was a damping device for use in a small space so it got the tick...as none of the usual suspension companies had at the time a solution for suzuki...[showa.kyb,etc]...they were aware of its down falls...they tryed to improve it in the tlr...because it has far to much internal friction...so changing direction is a harder task...and they are near imposible to valve correctly...as they can't flow large volumes of oil quick enough to cop with large and or high speed impacts [also know as the blow off effect]
Fork flex is a bad thing as it induces understeer....which is a very bad thing...it causes people to ride off the side of the road into hard objects when they over cook it and freak out....panic....etc....look at the first hard object they see and hit it....
as for the time it takes to filter down to production motorcycles...well we can only guess...my bet is on manifacturing costs...but thats only a guess

wow....quite a heated debate and tomato-throwing......all just on a simple Bling-Factor object

That's so not true. Everyone with half a brain (that's me in) knows that USD forks help to reduce world poverty and make Jessica Simpson want to rub you down with the juice from the musk gland of a Guatamalan lesser spotted tree frog.

I like beer.

Oh. are they supposed to be that way? I thought someone had stuffed up the putting together process. Uh, must go make an apology.

Then I' think I'll work on this brilliant idea I've had. If turning the forks upside down is a good thing, why not extend it and reverse the forks? Put the back wheel (and swing arm) at the front and the front wheel (and forks) at the back, Don't laugh, they laughed at the Earles fork too. And just ask any BMW nut how good they were.

Damn, that thing is ugly.

They are, afterall, a moving billboards. Aren't they?

And the bilboard owners want their bilboard to win the race.

All very nice on the track but for 99.9% of riders on the road

You could just as easily say they probably got updated so the fashion police wouldn't get them

I'd say 100% of road riders, but development comes from the track where factories want that extra 0.1% to win. If it wins on the track people think it will make them faster so they will buy that bike.

USD skrof are better for a bikes handling, but RWU forks are plenty good enough for the majority.

Think about slipper clutches. They have a definate advantage for good racers, but none whatsoever for a road rider "Ooh the back wheel locks when I change down too many gears". Ever heard of a clutch , or sympathy with your gearbox. Yet road bikes are appearing with slipper clutches, just because the racers can utilise that technology.

Simple equasion: (T*Rw)/m=s

T = Technology
Rw = Race wins
m = marketing
s = Sales

bling bling bling....... but can you ride it

front wheel hits the headers??? yes....it is very very possable with conventional forks

[Mental Trousers]

Slipper clutch?? Who needs a slipper clutch?? Just wind the idle up to 2500rpm for zero engine braking

earles were way a head of there time...and is a better system than any forks...same with girder type arrangments on the britten and a triumph factory racer I remeber seeing...and has also been seen on other bikes....the system used on the yamaha gts and bimota tesi is also good [better for braking] but lacks the adjustability of the girder type arrangments...bmw tele lever also has some very good merits....

okay....slipper clutches arn't nessicary at all...your right....but my god they are good...have you every ridden a big V-twin hard???? tip over a v-twin into a corner while using alot of engine braking your will probally end up in the weeds or cause a massive wooble....the have a lot of use for road riders....especially for attacking corners agressivly...

All I can think of here is that there are alot of people arguing against usd forks...that probally havn't got much feel when riding a bike...I can feel the diffderence between rwu and usd...you can hold a far tighter line with usd coz you don't have anywhere near the flex...hence less understeer...mid corner adjustments are far more accurate...

think about it....modern sports bikes of today would beat racer bikes of 5yrs ago around a race track....

Hi everyone,

I am a little bit curious, what are the reasons why some bikes have inverted front forks? Are there any benefits with regards to handling etc? Or is it just bike manufactures trying to be different?

Aside from the good things people have posted, USD forks do apparently have the disadvantage of more total weight. Apparently you have to have a stonger/less bendy (Re: heavier) top of the forks to get the advantage of the less bendy bottom bit. This can push cost up as well as more raw materiels and possibly and extra weld or four for the extra bracing. Or instead 'better' materials (Re: expensive) for construction to not increase the weight.

Apparently.
