RS VS F3 cornering speed?!

[BLUEKNIGHT911]

VSS THEORY

To a degree, yes. If you are pushing the front on entry or getting on the throttle too hard before you exit, VSS will cut your power. It's always a matter of balance. Trail braking on entry is a difficult technique to master. Hitting the apex and opening the throttle - it's all to easy to wind the grip wide open and mess it up. Do that right and you're smooth without noticeable intervention.

IMHO, the Spyder isn't comparable to 99 . ? % of the rest of the vehicles out there. I don't think you have enough time on one YET, to fully realize it's limitations. My 7 + yrs. with 3 different Spyders leads me to believe the VSS is speed sensitive .....SMOOTH isn't something the computer takes into account.............You seem to feel differently and I respect that, perhaps someday we will meet on a road that will challenge our riding abilities...............It will be " EPIC " :thumbup::thumbup::thumbup:..................Mike

I give up, I'm sorry this devolved into a forum fight. You can believe whatever you want to believe - I understand the software behind Bosch Vehicle Stability Systems. It's not a matter of belief on my part.

Depends....

Gonna have to go with how they are set up. Box stock or lightly modified. I notice here most are refering to the feeling and not the speed the op asked about. Considering the whole seating position I can see where the feeling is suggesting the speed. I can not compare as I Have not ryden an F3 nor care to but can say that those I ryde with that have changed over have not picked up any speed in the turns. Again we go back to...test ryde them both and see for yourself...:thumbup:

in here there have no test ride .so i just order a sm6 f3s.

thank you everyone.

Sorry Mike...
The VSS simply takes the inputs from the sensors, and figures out if you're doing something that is leading to an uncontrollable situation. If the yaw, steering angle, wheel SPEED, and others; are pointing to an ugly situation: you get an intervention.
She doesn't shut you down, based solely upon how fast you're going. Smoothness does count! :thumbup:

I have to agree with you Bob drive a smooth corner fast and you,ll have no problems.Watch any type of racing and you,ll soon see that a good driver that run,s a smooth corner will out perform some one thats trying to be to agressive.The G force set by the computer with the sensors and yaw rate will shut you down.

WHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAT

Hey NEWBIE !!!!! I'm not fighting with anyone ...... if you think there is a fight going on ....IT's IN YOUR MIND ......NOT MINE ......and if it's your opinion that SMOOTH fools the VSS , well you need to stop smoking whatever it is your smoking......You can be as smooth as Glass, but at a predetermined limit ( set by the BRP / Bosch engineers ) the VSS is going to be activated.........My understanding of the VSS is now verified by the NEW 2017 F-3 S model.........Mike :thumbup:

The Bosch VSS system takes inputs from the wheel speed sensors, the yaw sensor, the steering angle sensor and passenger presence switch.
The inputs from these six sensors are used to construct an internal model of the vehicle that is updated with blinding speed.

The passenger presence switch is used to determine, in a broad way, the CoG (center of gravity)

The steering angle sensor (sas) determines where the driver is intending for the vehicle to go.
Also, the difference in speed between the two front wheels based on the sas can be applied to the internal model.

The yaw sensor sends information from which the practical adhesion limit of the vehicle is calculated.

When this internal model shows that something bad is going to/or has happened it uses the braking system independently to bring the vehicle back into control as well as the ecu to manipulate power.
It knows it is in control when the internal model is deemed stable

Without this system the Spyder would be a very dangerous vehicle to drive.
Test drivers who have driven it without the VSS have said it was like piloting a lawn dart.
The system does not react to absolute speed.

Thank you, for that easily understood explanation.:clap: :firstplace: :2thumbs:

I wish that I could have said it, half as well as you did! pps:

The passenger switch is used to determine in a broad way the CoG (center of gravity)

From the steering angle sensors it knows what the difference in speed between the two front wheels should be and what the drive wheel should be be turning at.

It also uses the steering angle sensor to determine where the driver is intending for the vehicle to go.

The Yaw sensor sends information from which the practical adhesion limit of the vehicle is calculated and if the vehicle is about to go into an unsupportable drift.

The inputs from these 6 sensors are used to construct an internal model of the vehicle that is updated with blinding speed.

:agree:This is what I attempted to explain and failed to communicate in my posts yesterday.

Test ride both

I've got both, I think the F3 is faster around curves, because you feel more secure. The RS, you sit on top of it and the force is trying to knock you off of it. The F3 you sit more in to it in regards to seating positions. Just my .02

I test rode both and preferred the F3-t for the ride position. (Came off a 2008 GS so like the forward lean position) You have to ride them and see what you prefer, it's a lot of money to drop with out comparison shopping. Seeing what the OP wrote I will have to agree with that.
