Title: Sachs Skyhook Suspension
Post by: SachsGS on November 23, 2012, 05:23:22 PM
Those of you concerned about (quite rightfully) increasing complexity in offroad motorcycles brace your self because things are going to get even more complicated. Move over EFI and DFI because Sachs Suspension has just introduced "Skyhook" technology, a system that mounts sensors (accelerometers) on the sprung and unsprung parts of a motorcycle. The information derived from these sensors is fed into a computer that instantaneously modifies compression and rebound damping to suit terrain at that moment. Apparently it works extremely well. Presently available for street bikes it is only a matter of time before this technology works it's way offroad.

That's sounds pretty cool. How much do you reckon it will cost if they decide to bring it out?

I wonder how much the control module will cost if it craps out...

Am I the only one who thinks that advancing technology is a good thing?

If people didn't keep modernising stuff then we would all still be riding air cooled foopers with girder forks and short travel twin shocks.

I like advancing technology, but there needs to be some limits. The way things are going kids wont/already dont have the same chance to ride and race growing up that kids 10 years ago had. I say that because i beleive with the 4 strokes along with the recession it has already gone to far, and the addition of EFI,traction control, and "skyhook suspension" they will sell boring bikes that do most of the work for you... that we watch go around a track on tv.  Or maybe even worse, all of the above, but battery powered... Electronics on DIRTBIKES should be minimal.  Advance the "hard parts" and keep the rest out of competition.

well, i just think it makes for a more technical rider to understand what his machine is doing and how to correct its faults to better his riding as opposed to having the machine do everything for him. I also go by the premise that not all change is good.

While I agree with some of your points this new suspension and EFI or DI if all done to the same bike would mean that any rider could have a bike thats setup perfectly for every race. Less time setting your bike up means more time riding it.

I used to quite enjoy rebuilding my bikes and generally aintaining and fixing things on them while I was at home but when I got to a track I wanted to ride not mess around with clickers and jetting.

I'm with you, gpnewhouse7 , we should be advancing all the time but we seem to have stalled. Don't be afraid of a few electronics moving in ( so long as they don't clean the fridge out ). Here I go again EFI, is not a bad piece of Tec, fourstrokes have it twostrokes should also. Traction control would help with the fight against fourstrokes, all good stuff and available now. Manufactures aren't interested so what's stopping people like us having a go. There is no reason why a 250 T shouldn't out perform a 450 F with a little electronic help! In this forum is a guy putting a 250 T in a 250 F frame, a real nice job, but we could do so much more. I remember when CDI was thought to be the work of the devil!
In saying that I can't wait for this reed valve "flash in the pan" to finish and we can revert back to Rotary Valve!

with all the technology being incorporated in to modern bikes, I'm surprised there haven't been major advancements in suspension. Different designs, different technology, electronics? etc..... In my mind, a modern,  well tuned motor, in stock form, has plenty of power. Controlling that power and being able to redirect it at a high rate of speed, over varied types of terrain, is the direction I think technology should go. I'll take better suspension over more power any day ....

Average off road rider? Yes. Professional racing? No. Where is the fine line of who actually is doing the riding? The bike or the rider? F1 had this suspension in the early 90's and was removed due to this fact. It will simply allow people to ride faster, and that isn't always a good thing. Modern GP has 135lb(If not lighter) riders on 200hp 1000cc bikes. How? Traction control...

All of the technology is cool, and will make bikes go even faster... even with less skilled riders. Todays bikes are fast enough, take out the "fight" for traction and add "auto adjust suspension" and the tracks will just get more crazy to keep up.  This would both add cost to an already expensive sport, and add more danger for serious injuries when it becomes common for your local track to have 4th gear 160ft quads... like this one



Like i said, more danger for SERIOUS injury. No doubt that some of the technology could help safety, but When you have to go bigger and bigger to push it to the limits it just makes your mistakes that much more serious.

The only reason for tracks getting faster has nothing to do with Technology. The reason you see faster bikes on tracks today is that tracks are flatter to adjust to 4t power characteristics. 4 strokes like flat ground, not rough terrain.  This allows for bigger jumps which at this point is causing a list of injuries and so far even deaths.

i have a 200hp 1000 cc full superbike with out traction control , its a lot of fun to ride

Jumps have been getting bigger and bigger ever since motocross began. Modern bikes can do much larger jumps than the old short travel suspension and they do them more safely. Besides as bikes develop so will the safety gear that is used when riding them.

This would be due to modern suspension. Old bikes can be launched as well. And as for safety gear, sure didn't help Jantz out any...

there are some other videos on youtube , one on board view and yes the jump is big but its not huge and has a safe landing

That's pretty cool technolgy .It would be great to have your suspension  controlled that way.I doubt with the complexity all of it will ever find it's way on to a dirt bike but just like the F1 cars and your family sedan,much of it trickles down eventually,and we are the better for it. 8)

As delivered on a street bike, Sachs Skyhook suspension has four different settings that can be selected for the type of ride/action a rider wants.

 Back around 1997 KTM introduced the PDS system and it was lighter,cheaper,easier to maintain and allowed for a better airbox design (more power). The rate rise in this system was achieved hydraulically rather then mechanically as in a conventional single shock rising rate set up. I wonder if with a system like the Sachs we'll see a rear suspension that is non linkage with programmable electronic/hydraulic rate rise?

Ford, F1 no longer uses this. Matter of fact, not since 93 haha. This was due to some team not being able to afford the added expense, and to keep drivers like michael schumacher from abusing it(Cheating Bastard)

Lol,yeah,I know,maybe I wrote that wrong.I was just referring to F1 technology eventually trickling down to regular autos.It's a test bed for automakers,and has been for years.That doesn't mean regular cars get the exact systems used on F1 cars,but parts thereof and the technology certainly make their way to production lines.

I disagree. I believe every automobile/motorcycle owner should adjust their ignition advance manually with a lever. If it is good enough for a Ford Model T, or an old Indian, it should be good enough for you or those highfalootin perfessional racers.

Electronics are the devil!

Don't forget to retard the ignition when you use the hand crank to fire the beast up.

No they are not , they have only 3 setting that you can change for different conditions , they are not self correcting or does the system have a brain to work out the best setting
