250 MotoGP front forks.

[FROSTY]

Can someone explain the front fork set up on the 250 GP bikes.
It looks like they have 2 upside down forks each side .
Whats the idea ?

[R6_kid]

Do you mean like this? If so I think its the Nitrogen canister.

Here's a similiar setup, thought it doesn't specifically say what he extra tube is for, thought it does mention 'completely separated rebound and compression'

USDs are good.
So double the USDs should be twice as good.
Duh!!

[Devil]

Frosty, pretty sure it's an external reservoir like you'd find on a rear shock...

Wierd how something so aesthetically simple is so desireable. Maybe it's the gold?

I mean, I know the magic they would do to any bike they are fitted to, but even just having them mounted on the wall in your living room would be cool.

they prolly cost as much as a whole motorcycle too

Around 25k NZ$. The cartridge inserts are gas charged and the external reservoirs are indeed nitogen filled. Seperate rebound from compression, left leg compression, right leg rebound. Gas pressure 5 bar.
The two works Yamaha MotoGP bikes have total TTX technology in them, no shaft displacement, so they only need a very small internal reservoir to account for oil heat expansion only, that is why they do not have external reservoirs.

nah rob taylor just likes to rip off us hard working kiwis with his exorbitant prices ;) thats why i only buy from overseas.

This is the trouble with forums isnt it! So many uninformed clueless idiots who make sweeping statements. The forks on those 250 MotoGP bikes are specially hand built by the race department at Ohlins,and are very low volume production, use exotic parts and are not available to the general public.
They are FAR removed from the ''Road and Track'' production forks that are available for road bikes.
It would be appropriate that you apologise but Im not holding my breath.
One day you may lose your job due to overseas competition from parasites in predominantly the US, think about it....

I actually think he believed what he was saying, misinformed assumptive soul.

[R6_kid]

Haha, what an interesting turn this thread has taken! I heard somewhere that a set of MotoGP forks is around the $40k mark, though I'm guessing they'd work out some sort of package including technical support in the form of onsite staff (such as you get at some race events from RT) thrown in with the purchase/lease of the technology as surely Ohlins gets to take away any data to further improve their product.

I don't believe your figure of 25 grand. That must be for each fork leg right?

[Robert Taylor]

Of course FGR800 are now an old fork, soon to be 2 model years old and being superceded by TTX technology. The price quoted on that site is obviously either a serious misprint, misleading advertising or that company is running as a charity. The price quoted is a fraction ( and I seriously mean a fraction ) of a distributors ( and not then a sub distributors ) price ex Ohlins.
250 MotoGP forks are a smaller version again with different dimensions, settings etc. They are handbuilt by the race department in usually one small run only and must be ordered well in advance.
Trackside support is an extra that must be paid for. For a MotoGP team to secure the full time support of one Ohlins technician for a season is 100,000 euros plus parts.
Here in NZ we grizzle just at the purchase price and many people think we have huge margins so that we can offer the trackside support we do. The reality is nowhere near as rosy as some would like to think, lucky we genuinely enjoy helping people.

If Ohlins themselves had even 20% margin in those forks Id be surprised. MotoGp technicians have to fly all around the world, be domiciled, be fed, be paid. That means a seperate invoice.

For $30k you'd be hoping to feel like you were riding on a magic carpet!

For now I'm quite happy with the ride improvement provided by $2000 worth of Ohlins rear shock, fork springs and emulators!

[Morcs]

So if we put some of those forks on a hyosung 250, it would be able to compete with the 250 GP bikes?

No, thank goodness.
Buying a set of those forks is but one of the items to get you on the grid as a privateer, plus you will need a spare bike kitted with them as well. 2, maybe 3 TTX shocks and spring options for varying circuits. Access to Ohlins engineers and some sort of contract for service. But then you are not going to get the same stuff as the factory teams. Thats the reality of world championship racing. The budgets to run this sort of stuff exist because there are way more people to make the money go round. Nothing wrong with that.

[gatch]

If possible, can it be explained in the tongue of the common man, what you get for the 25-30k set of forks that you wouldn't in a shiny new set of off the shelf ohlins ?

In a Nut shell you get a complete Factory RSVR Aprilia or a 1098S Ducati the other way you have a pair of forks sitting in your shed :blink: LOL Pretty much you get Very accurate machining & fitting of very expensive materials to near perfect spec , the other you get excellent road/track useable forks that offer you still great feed back & quality at 3/4 of the price . :blink:

[Taz]

If i fit a pair of these fancy forks to my Guzzi then I may just have forks that go up and down!! That'd be a novelty.

Couldn't help but notice whilst watching the GP last night that the Ducati GP9 has something similar with external reserviors.

Thanks for the informative reply Robert, but it was a p/t aimed at hyosungs and chaos rider in particular :woohoo:

Very low volume production, hand built in race department equals much higher price

18 step titanium nitriding / grinding of fork tubes, very slippery action

Gas charged cartridges

Exotic materials

Absolutely no cost compromises

ETC ETC

All of the Ohlins forks have external reservoirs except for the two works Yamahas that have through rod cartridges

Yes I know, when you mention that bike name and Ohlins its akin to mentioning Sue Bradford and Claudia Schiffer in the same sentence.

wow~! he said a funny!

In plain english, for us mortals running fun laps in Pukekohe (not even racing)

a) what difference would I feel comparing a standard ducati fork set and this TTX thingamajig if it is put on and run without setup?

b) what difference would I feel comparing a standard ducati fork set and this TTX thingamajig if it is put on and set up by your excellent skills?

c) do they also have ttx spoon and ttx knife to go with the fork?

d) I need to get my mates some of these forks so they can eat my dust.

a) better than stock.

b) fuckin awesome ! What you thought was the shit will now make you shudder in disgust at how appalling it actually was.

c) anything is possible with enough money.

d) good suspension will not make you fast, but will definitely make a fast rider faster.

You've tried them?

[Robert Taylor]

You've tried them?

Maybe he hasnt but he has answered in p0lain English. Pre-orders being taken now for 2010 production, if you send me a 15k deposit that will get the ball rolling.

[puddy]

Technical support! Of course! Always wondered what the girls were for!

[gatch]

You've tried them?

Unfortunately I haven't, although it is my understanding from talking with various motorcycling enthusiasts that standard suspension on 98% of bikes is rubbish, made to be ADEQUATE for people of average weight and riding style.

Ride to any extremes and you will be amazed at the difference with tuned suspension.. So I'm told..
