haha yeah that was so funny! Everyone was down there having a look, myself included!
The explaination Sam gave me was pretty convincing and it certainly seemed like a good idea to be able to flick a switch to change between 2 settings. The new shock for the ZX10 sounds even better!

How do these servo's know the current location? GPS? Its actually pretty simple to do!
Could they remove the clickers and work very accurately between the clickers to somewhat more accurately tune the suspension? By moving the needle valves accurately?

Brake lever and throttle sensors. Grab brake and gett oodles of compression damping at the front, let it go and it softens up. Give it some jandle and the rebound winds off at the back.
There are a multitude of in veterans that would take some time to map, but simple enough.
Tilt sensors/speed sensors if you wanna get stupidly complicated. Even a gyro. Once you know the data they send, you could quite easily make an adjustment for it.

Would you like me to organise some of those instead?

GPS was used with the Yamaha WSBK bikes yes, but the signal has to be very clear. You also dont want the opposition moving the position beacons!
The needle valves are moved exceptionally accurately. More will follow of how this all works after I return from Stockholm mid October

Short answer...YES!

You are not as silly as you look Drew! Add to that throttle position, rate of change of throttle position, gear selected, acceleration etc. The point is much of that info is already there in current and upcoming oem original fitted ECUs / input signals and its just a matter of piggybacking another black box into the ECU, much like a dynojet power commander.
Technolgy is there to be embraced.

We had a great test with new Ohlins TTX25 gas cartridges at VMCC round 3. We had a set fitted into the BMWs of Sloan Frost and also Dion Sellers. In Dions case we were able to assist him in faciliatating a sale of his old cartridges to another BMW rider and he got a great return on them.While these two bikes were clearly going to run at the front anyway it was a comparison against the NIX30 cartridges that they had both been previously running and were in fact very happy with. Sloan is NZ#3 in NZSBK and the riders who finished ahead of him ( Robbie and Andrew ) also run our Ohlins equipment and solid trackside backup.
We had basically installed these cartridges at the bone stock standard settings that Ohlins deliver them with as we didnt want to second guess. Straight away Sloan reported that compared to his beloved NIX30s brake dive support was noticeably better but also the feel and feedback he was getting from the front end was at a new and higher level. Also through turn 2 which is treacherous with abrupt bumps the front end railed through and absorbed the bumps much more nicely. Dions comments concurred exactly with Sloans but I expected with Dion that because his riding style is a little different that he would soon enough ask for a slightly higher oil level to stop bottoming out, that proved to be the case
We had a plan beyond that because we had run a set on our suspension dyno and had a shim stack setting change that would yield even more brake dive support. This we applied to both Dions and Sloans forks at the same time, but we also deliberately returned Dions oil level back to the standard setting. Both riders reported an even further improvement with no negative side effects whatsoever. After these changes Sloan rattled off a number of laps in the mid 6s and that was pretty good considering he hasnt done a lot of racing recently, the bike is brand new and track temperature didnt climb above 16 celsius. We did no work with the rear but know we need to as there was a little bit of pumping on corner exit to solve, but thats going to be easy and we have also firmly established a direction.
Dions previous best lap ever on that bike was a high 7 in the middle of summer with fresh tyres and a hot grippy track. Yesterday he easily rattled off a 7.3.
The other factor that was very encouraging is that revalve time was only about 2 minutes longer than it would have taken with the NIX30s. Again like the NIX system the left leg is totally compression and the right leg is totally rebound. The cartridge rod can be removed with the forks still in the bike, all you need to do is to quickly remove the top cap, spring and preload spacer and then with a special tool remove the top cartridge cap and rod assembly as a sub unit. Take it to the bench and valve it. Then reinstall with an extra compressive holding tool and clip that when released automatically resets the dividing gas piston to its correct static position.
Ohlins have really thought about that AND CLEARLY RECOGNISE THAT IF A SETTING CHANGE IS REQUIRED FOR DIFFERENT CIRCUITS AND CONDITIONS IT SHOULD BE ABLE TO BE ACCOMPLISHED VERY QUICKLY. We figure that we could if required do one fork in as little as 10 minutes. Compare that to a competing brand where relatively its an absolute nightmare. You have to in the case of that product remove the fork, then remove the cartridge, then you require a whole raft of tools to remove a sub assembly to access the shim stacks, then change and rebleed, reassemble and refit to the bike . You can imagine that takes an enormous amount more time, and that time just may not be available. So you may have a set of forks that could in fact be made to work better but its too intimidating to make changes. Moreover anyone that sells ANY product and says ''its perfect out of the box and you will never have to make changes'' is deluding you and himself. ''Setting banks'' of alternative settings exist for our product and for other products ( we have seen for other products ), the reason they exist is to provide alternative settings to suit different scenarios and much depends on the tenacity of the suspension engineer to insist on getting the best out of it. They might work pretty damn good out of the box, but might they be able to work even better???? We could say our TTX25 cartridges out of the box were perfect and if we had not made a setting change Sloan and Dion would still have gone away ecstatic with their new equipment. BUT, we did insist on making a change and that yielded a further improvement. Moreover, we are not engaged in any other trackside activities that takes away valuable time from the absolute focus of all that we do, suspension.
That change we had previously dyno tested so we were by no means ''flying blind'', we would perhaps sound a little ''arrogant'' in saying this but we knew pretty much exactly what the riders were going to say. We have spent $35k on this new suspension dyno and thus far its money well spent. ( Not only for racing ) No other motorcycle focused suspension company in New Zealand has the committment to invest in lifting the game so much.
In terms of performance and the ability to make setting changes very very quickly ( dont understimate that ) Ohlins TTX25 are very clearly top of the tree. Moreover they are a true GAS PRESSURISED cartridge.
