Hi vital. I'm wondering why nobody brought this op before. What is the ( gas springs ) on the right side off the bike. Never seen this before. Can somebody explain.
Thanks.

Looks like a component of a data logger for chassis/suspension testing. It records the movement of the chasis while the rider puts in laps. If the rider reports a troubled area (whoops, cornering, etc.) the team can repeat that section on a suspension dyno with different suspension settings until they find a setting that seems to have made a positive change. They'll test the new setting with rider at the track and verify if it was a good or bad change. In theory, this is a much faster route than troubleshooting only at the track.

Not sure why it would be on the bike during a photo or video shoot... Maybe it's something Honda will be keeping on the bike permanently for more data recording/telemetry. Maybe it's not even what I'm describing, but it sure looks like it.

This video I produced for FC shows a little bit of similar testing.

In other words, its probably a displacement transducer, not a gas strut/spring.

Yes thats a linear potentiometer used to measure travel....as the rod moves in and out the resistance changes( between 0-5volts usually) and the software is calibrated to translate to a displacement...Penny amd Giles is a typical manufacture.

So the team can either validate what the rider is feeling or tell them they're full of shit? I like it.

I have a Showa 5.3 spring from Japan in this same color (candy apple red ), in "like new" condition, if anyone is interested.

All I know is that shock and spring are almost enough of a reason to get a Honda! That's bike porn!

Which suspension companies us this hi tech setup? Anyone besides Factory Connection?

I doubt they can really tell you much from it, "yes it went all the way down" "no it didn't" "yes it did" "no it didn't"

damn a 5.5 is my normal rate for a Honda, mind you the 2017 suspension has changed so that MIGHT alter what I would normally use ... I would be interested in how you went about getting it I didnt know the average Joe Bloggs could get these!

They can use this shock position data and (through some math) can see shock velocities, accelerations, etc. The data can't replace a rider's feedback, but if they can find correlations between the data and the rider's comments they can make more informed decisions about what settings to change and then quantify whether or not the change gave the desired result (through more data logging and rider feedback).

A lot of that back and forth is what has gotten many riders completely lost in their setup!

Yeah it does...looks like anodized candy Apple red...if there is such a thing.

data is all cool and fancy but totally worthless if the rider is "not comfortable" on the bike, "not used" to the bike.
just saying

Data is there as a tool, some people are good at interpreting that data other prefer the 'seat of their pants feel' ...so yes I agree with your statement

I said data can't replace a rider's feedback, it is used in addition to rider feedback. It is a tool so that (hopefully) the team can learn more about what the bike is doing when a rider gives certain feedback, if they can learn those trends it gives them more knowledge about how to make setup changes. That way, on race day after practice if the rider comes in and says the bike is doing XYZ the engineers/mechanics have a better chance at moving the setup in the right direction on the first try. Do they always get it right? Hell no. That's racing, that's what separates motorsports from stick and ball sports.

Data is a tool and it's only as good as the person interpreting it. I would like to think at HRC the engineers are pretty good at what they do and if they didn't get meaningful information from it they wouldn't waste their time. Not all teams have the personnel to make it useful.

velocity vs. time graphs is very useful. I work daily with airplane hydraulics. And i use this stuff often.
